description: In this letter, we report our observation of an extraordinarily rich phase diagram of a LaScO$_3$/SrTiO$_3$ heterostructure. Close to the superconducting transition temperature, the system hosts a superconducting critical point of the Infinite-randomness type characterized by an effective dynamical exponent $νz$ that diverges logarithmically. At lower temperatures, we find the emergence of a magnetic field-tuned metallic phase that co-exists with a quantum Griffiths phase (QGP). Our study reveals a previously unobserved phenomenon in 2D superconductors -- an unanticipated suppression of the QGP below a crossover temperature in this system. This concealment is accompanied by the destruction of the superconducting quantum critical point signaled by a power-law divergence (in temperature) of the effective dynamical exponent. These observations are entirely at odds with the predictions of the infinite-randomness scenario and challenge the very concept of a vanishing energy scale associated with a quantum critical point. We develop and discuss possible scenarios like smearing of the phase transition that could plausibly explain our observations. Our findings challenge the notion that QGP is the ultimate ground state in two-dimensional superconductors.

description: Topological transitions in bubbling half-BPS Type IIB geometries with SO(4) x SO(4) symmetry can be decomposed into a sequence of n elementary transitions. The half-BPS solution that describes the elementary transition is seeded by a phase space distribution of fermions filling two diagonal quadrants. We study the geometry of this solution in some detail. We show that this solution can be interpreted as a time dependent geometry, interpolating between two asymptotic pp-waves in the far past and the far future. The singular solution at the transition can be resolved in two different ways, related by the particle-hole duality in the effective fermion description. Some universal features of the topology change are governed by two-dimensional Type 0B string theory, whose double scaling limit corresponds to the Penrose limit of AdS_5 x S^5 at topological transition. In addition, we present the full class of geometries describing the vicinity of the most general localized classical singularity that can occur in this class of half-BPS bubbling geometries.

description: Conversion to particularly animal-friendly stabling (PAFS) is one of the programs for which Swiss farmers receive direct payments from the government. This conversion to PAFS is analysed within a structural equation model in order to 1) review the link between intention to convert and observed conversion behavior, 2) prove the influence of personal experience on changing attitudes and norms, after having converted. The behavior model encompasses three theoretical constructs which influence the Behaviour: Attitude toward PAFS and Subjective Norm regarding PAFS, which both affect Intention to perform PAFS. Lastly, Intention influences the Behavior, i.e. observed conversion to PAFS. These variables are available for two time points, so one can differentiate between Conversion1 and Conversion and so on. In addition, Behavior influences Attitude 2 and Subjective Norm of the second time point so one can investigate if there is any effect of personal experience on these variables. All in all the models have good fit, but results cannot be seen as supporting the underlying theory. At least the results indicate the weakness of the Theory of Reasoned Action regarding the intention-behavior-relation, which has already shown in other behavior domains. But also the effect of personal experience on attitudes and subjective norm cannot be confirmed.

description: We propose a method for enantio-detection of chiral molecules based on a cavity-molecule system, where the left- and right-handed molecules are coupled with a cavity and two classical light fields to form cyclic three-level models. Via the cavity-assisted three-photon processes based on the cyclic three-level model, photons are generated continuously in the cavity even in the absence of external driving to the cavity. However, the photonic fields generated from the three-photon processes of left- and right-handed molecules differ with the phase difference π according to the inherent properties of electric-dipole transition moments of enantiomers. This provides a potential way to detect the enantiomeric excess of chiral mixture by monitoring the output field of the cavity.

Há um pouco mais de cinco anos, os Pankararu Opará, reivindicam da FUNAI, a regularização de uma Reserva Indígena, isto porque, para este Povo, trata-se de um território considerado o mais sagrado, próximo às antigas Cachoeiras Sagradas submersas após a construção da hidrelétrica de Itaparica, que naufragou a gruta dos padres, entre outros lugares de rituais realizados pelos antepassados da Nação Pankararu. O estudo com base etnográfica e revisão bibliográfica através da Nova Cartografia Social do Povo Pankararu Opará (2022) e dos estudos, sobre a ontologia fenomenológica pensado a partir de Foucault (2007), Sartre (1997), entre outros autores clássicos, vem a possibilitar caminhos em torno da multiculturalidade, na sustentabilidade simbiótica que promova o equilíbrio dos ecossistemas e da vida humana. O Rio São Francisco ou Rio Opará, na cultura dos Povos Originários, é considerado mais que uma divindade, é o Rio que cria e recria os elementos da vida, e a vida humana como parte integrante dele, tornando-se guardiões. É nesta cosmologia, que os enunciados do Rio com um ente, aparecem na ritualidade xamânica do Pajé Jaguriçá, tornando-se um ser personificado, detentor de direitos.

description: We study perturbations of non-recurrent parameters in the exponential family. It is shown that the set of such parameters has Lebesgue measure zero. This particularly implies that the set of escaping parameters has Lebesgue measure zero, which complements a result of Qiu from 1994. Moreover, we show that non-recurrent parameters can be approximated by hyperbolic ones.

Longitudinal follow-up of pediatric human immunodeficiency virus infection

Publisher: name: University of British Columbia

description: This longitudinal follow-up study was undertaken to document the clinical history of virologic parameters in HIV-infected children, including the evolution of resistance to the antiretroviral agents zidovudine and lamivudine. The effect of differing therapeutic regimens on these parameters was studied. Nine pediatric patients from the Oak Tree Clinic in Vancouver were evaluated. Serial CD4 cell counts, plasma viral loads and all combinations of antiviral therapy were recorded from the time of diagnosis. Results showed that eight out of nine patients received either single or double drug combinations as initial therapy and the remaining patient was started on a triple combination therapy regimen. At last follow-up, the median viral load was 2,415 copies/mL and the median CD4 count was 765 cells/μL. The median change in viral load from baseline was -53,180 copies/mL and CD4 count was +54 cells/μL. For the entire observation period, only four cases achieved undetectable plasma viral loads. Of these four, there is only one case of durable suppression, this being the only patient to start on a triple drug regimen. Sequencing showed that 7/9 patients carried isolates that were AZT resistant. Of the two patients with susceptible isolates, one is on triple therapy and the other remains on dual therapy (including AZT) with a viral load of 16,000 copies/mL. There were six cases of 3TC resistance, with three patients carrying susceptible isolates. Of these three, one is no longer on the drug and another is the maximally suppressed, receiving triple combination therapy as the initial regimen. Studies in adults have shown that dual combination therapy is inadequate in suppressing viral replication and preventing the evolution of drug resistance and disease progression. It is during the developmental stages of childhood that adequate antiretroviral therapy will have its greatest impact in minimizing the neurodevelopmental effects of HIV disease. Thus, triple combination regimens must be selected to achieve maximal virologic containment and minimize the development of antiretroviral resistance.

description: We use particle tracking velocimetry to study Eulerian and Lagrangian second-order statistics of superfluid $^4$He grid turbulence. The Eulerian energy spectra at scales larger than the mean distance between quantum vortex lines behave classically with close to Kolmogorov-1941 scaling and are almost isotropic. The Lagrangian second-order structure functions and frequency power spectra, measured at scales comparable with the intervortex distance, demonstrate a sharp transition from nearly-classical behavior to a regime dominated by the motion of quantum vortex lines. Employing the homogeneity of the flow, we verify a set of relations that connect various second-order statistical objects that stress different aspects of turbulent behavior, allowing a multifaceted analysis. We use the two-way bridge relations between Eulerian energy spectra and second-order structure functions to reconstruct the energy spectrum from the known second-order velocity structure function and vice versa. The Lagrangian frequency spectrum reconstructed from the measured Eulerian spectrum using the Eulerian-Lagrangian bridge differs from the measured Lagrangian spectrum in the quasi-classical range which calls for further investigation.

description: Theoretical models suggest that decisions about diet, weight and health status are endogenous within a utility maximisation framework. In this paper, we model these behavioural relationships in a fixed-effect panel setting using a simultaneous equation system, with a view to determining whether economic variables can explain the trends in calorie consumption, obesity and health in OECD countries and the large differences among countries. The empirical model shows that progress in medical treatment and health expenditure mitigates mortality from diet-related diseases, despite rising obesity rates. While the model accounts for endogeneity and serial correlation, results are affected by data limitations.

description: A separable quantum state shared between parties $A$ and $B$ can be symmetrically extended to a quantum state shared between party $A$ and parties $B_1,\ldots ,B_k$ for every $k\in\mathbf{N}$. Quantum states that are not separable, i.e., entangled, do not have this property. This phenomenon is known as "monogamy of entanglement". We show that monogamy is not only a feature of quantum theory, but that it characterizes the minimal tensor product of general pairs of convex cones $\mathsf{C}_A$ and $\mathsf{C}_B$: The elements of the minimal tensor product $\mathsf{C}_A\otimes_{\min} \mathsf{C}_B$ are precisely the tensors that can be symmetrically extended to elements in the maximal tensor product $\mathsf{C}_A\otimes_{\max} \mathsf{C}^{\otimes_{\max} k}_B$ for every $k\in\mathbf{N}$. Equivalently, the minimal tensor product of two cones is the intersection of the nested sets of $k$-extendible tensors. It is a natural question when the minimal tensor product $\mathsf{C}_A\otimes_{\min} \mathsf{C}_B$ coincides with the set of $k$-extendible tensors for some finite $k$. We show that this is universally the case for every cone $\mathsf{C}_A$ if and only if $\mathsf{C}_B$ is a polyhedral cone with a base given by a product of simplices. Our proof makes use of a new characterization of products of simplices up to affine equivalence that we believe is of independent interest.

We show that GEM can be described by the dynamic formation of polaritons in k-space. This picture highlights the flexibility and robustness with regards to the external control of the storage process. Our results also show that, as GEM is a frequency-encoding memory, it can accurately preserve the shape of signals that have large time-bandwidth products, even at moderate optical depths. At higher optical depths, we show that GEM is a high fidelity multi-mode quantum memory.

description: Agricultural land use does not only concern farmers, but also has a large number of social and environmental effects. Consequently, it is to be assumed that farmers have to use financial resources as well as labour in order to provide these services. Using the nonparametric method of Data Envelopment Analysis (DEA), we calculated the economic as well as the ecological efficiencies of farms and examined whether farms are able to succeed in combining ecological and economic efficiency. In addition to this analysis, we studied the driving factors of the respective efficiencies. The study was carried out in four typical production regions in Bavaria which vary in their proportions of grassland as well as their yield potential; thus, the study regions reflect a gradient of agricultural land use which is typical for Southern Germany. In all regions, a farm survey was conducted covering a total of 122 farmers.

description: In this work, we studied the slow-roll approximation of cosmic inflation within the context of $f(R,T)$ gravity, where $R$ is the scalar curvature, and $T$ is the trace of the energy-momentum tensor. By choosing a minimal coupling between matter and gravity, we obtained the modified slow-roll parameters, the scalar spectral index ($n_s$), the tensor spectral index ($n_{\textrm{T}}$), and the tensor-to-scalar ratio ($r$). We computed these quantities for a general power-law potential, Natural & Quartic Hilltop inflation, and the Starobinsky model, plotting the trajectories on the $(n_s,r)$ plane. We found that one of the parameters of Natural/Hilltop models is non-trivially modified. Besides, if the coupling is in the interval $-0.5 < α< 5.54$, we concluded that the Starobinsky-like model predictions are in good agreement with the last Planck measurement, but with the advantage of allowing a wide range of admissible values for $r$ and $n_{\textrm{T}}$.

description: This study examines whether there is spatial integration between and within paddy markets in the North and South of Vietnam. The empirical model developed uses estimates of transfer costs to generalize Ravallion's model of spatial market integration to allow for threshold effects. A sequential testing strategy is used to test for market segmentation, the number of thresholds, long-run integration, informational efficiency, and the 'Law' of One Price within an error-correction framework. We find no threshold effects and weak evidence of paddy market integration between northern and southern Vietnam. There is, however, evidence of both threshold effects and stronger market integration within the Red and Mekong River deltas. Whenever price spreads exceeds their thresholds at least 60% percent of price changes are transmitted between regional markets within a month. Nonetheless, the instantaneous version of the 'Law' of One Price only holds for a few regimes and market pairs. These results suggest that national level policies cannot be relied upon to stabilize or support paddy prices in Vietnam. Instead, policies need to be designed with the specific production, consumption and marketing characteristics of northern and southern Vietnam in mind.

description: This paper reports the findings from a discrete choice experiment study designed to estimate the economic benefits associated with rural landscape improvements in Ireland. Using a mixed logit model, the panel nature of the dataset is exploited to retrieve willingness to pay values for every individual in the sample. This departs from customary approaches in which the willingness to pay estimates are normally expressed as measures of central tendency of an a priori distribution. In a different vein from analysis conducted in previous discrete choice experiment studies, this paper uses random effects models for panel data to identify the determinants of the individual-specific willingness to pay estimates. In comparison with the standard methods used to incorporate individual-specific variables into the analysis of discrete choice experiments, the analytical approach outlined in this paper is shown to add considerably more validity and explanatory power to welfare estimates

description: This paper discusses the X-ray halo around the Swift gamma-ray burst GRB 050724 (z=0.258), detected by the Swift X-Ray Telescope. The halo, which forms a ring around the fading X-ray source, expands to a radius of 200" within 8 ks of the burst exactly as expected for small-angle X-ray scattering by Galactic dust along the line of sight to a cosmologically distant GRB. The expansion curve and radial profile of the halo constrain the scattering dust to be concentrated at a distance of D = 139 +/- 9 pc (from Earth) in a cloud/sheet of thickness delta-D < 22 pc. The halo was observed only out to scattering angles of 200", for which the scattering is dominated by the largest grains, with a maximum size estimated to be a_max ~ 0.4-0.5 um. The scattering-to-extinction ratio was estimated to be tau_scat/A_V > 0.022; this is a lower limit to the true value because contribution from smaller grains, which scatter to larger angles, was not directly observed. The line-of-sight to the GRB passes close to the Ophiuchus molecular cloud complex, which provides a plausible site for the scattering dust.

description: Models of gravitational decoherence are not commonly applied to ultra-relativistic systems, including photons. As a result, few quantum optical tests of gravitational decoherence have been developed. In this paper, we generalize the gravitational decoherence model of Anastopoulos and Hu (arXiv:1305.5231) to photons. In this model, decoherence originates from a bath of stochastic gravitational perturbations, possibly of fundamental origin. We derive a master equation for general states of the electromagnetic (EM) field; the only free parameter is a noise temperature $Θ$ of the gravitational fluctuations. We find that interference experiments with long baselines, accessible in near-future experiments, can, in principle, lead to strong constraints in $Θ$.

description: Bishop's measure theory (BMT) is an abstraction of the measure theory of a locally compact metric space $X$, and the use of an informal notion of a set-indexed family of complemented subsets is crucial to its predicative character. The more general Bishop-Cheng measure theory (BCMT) is a constructive version of the classical Daniell approach to measure and integration, and highly impredicative, as many of its fundamental notions, such as the integration space of $p$-integrable functions $L^p$, rely on quantification over proper classes (from the constructive point of view). In this paper we introduce the notions of a pre-measure and pre-integration space, a predicative variation of the Bishop-Cheng notion of a measure space and of an integration space, respectively. Working within Bishop Set Theory (BST), and using the theory of set-indexed families of complemented subsets and set-indexed families of real-valued partial functions within BST, we apply the implicit, predicative spirit of BMT to BCMT. As a first example, we present the pre-measure space of complemented detachable subsets of a set $X$ with the Dirac-measure, concentrated at a single point. Furthermore, we translate in our predicative framework the non-trivial, Bishop-Cheng construction of an integration space from a given measure space, showing that a pre-measure space induces the pre-integration space of simple functions associated to it. Finally, a predicative construction of the canonically integrable functions $L^1$, as the completion of an integration space, is included.
A comparison of glottalized resonants in Sänčatän and St’át’imcets
Creators: name: Caldecott, Marion Gerda
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is a comparison of the glottalized resonants in Sancaean and St'at'imcets, two Salish languages. The Licensing by Cue hypothesis as proposed by Steriade (1997) accounts for the distribution of glottalized resonants based on their phonetic cues. The goal of this thesis is to apply the Licensing by Cue hypothesis to the glottalized resonants in Sancaean and St'at'imcets, and evaluate its success in accounting for these two languages. Sancaean is a North Straits, Coast Salish language which does not permit glottalized resonants word-initially. St'at'imcets is an Interior Salish language which allows glottalized resonants word-initially but only in a particular morphological context. Licensing by Cue suggests that glottalized resonants do not occur word initially because of a lack of a supportive context for cues. The distribution of resonants glottalized as a part of a morphological process, namely the actual in Sancaean and the inchoative in St'at'imcets, should also be governed by the same phonetic factors. This thesis first examines the glottal timing of glottalized resonants in both languages. Preliminary phonetic evidence is given for glottalized resonants in Sancaean, which confirm that glottalization is attracted to stress. In contrast, in St'at'imcets, it is perceived that glottalization is repulsed by stress. Modifications are proposed, which enable the hypothesis to account for the timing of glottal events. It is argued, however, that even after such modification, the Licensing by Cue hypothesis is not sufficient to account for the distribution of non-derived glottalized resonants. The same is shown to be true for derived glottalized resonants. The distribution of glottalized resonants is governed by the interaction of three levels of constraints: phonetic constraints, which determine glottal timing, and phonological and morphological constraints, which govern the distribution of glottalised resonants. Also briefly discussed in this thesis are issues related to the relationship between /ʡ/ and glottalized resonant, whether [cg] or [creak] should be used to characterise glottalised resonants, and the Proto-Salish morpheme for the imperfective. Based on the research presented in this thesis, it is concluded that Sancaean and St'at'imcets glottalised resonants do not show strong support for a hypothesis which argues for a strong phonetic presence in phonology. While a cue-based approach can account for the phonetic timing of glottal events for glottalized resonants, segment distribution is determined by phonological and morphological constraints.
Taxation Concessions As Instruments Of Agricultural Policy

description: Economists have rarely considered the implications of taxation systems for the agricultural sector. Management specialists and accountants have usually approached the issue from the perspective of how farmers and landowners can avoid it. Little has been written on the extent to which the special treatments that agriculture commonly receives in national tax systems impact on the sector and its performance. This paper considers these broader issues and builds on an inventory of tax treatments compiled for the OECD by one of the authors. Tax concessions can act as forms of support to incomes and wealth accumulation, though the identification and quantification of this support present fundamental conceptual difficulties and practical problems. Taxes are often advocated as instruments of environmental policy, and these may have income implications. Concessions given by capital taxes, in particular, constrain structural adjustment. Differential tax treatments can also impact on patterns of international trade by distorting comparative advantage, as perceived by farm operators. Some of these effects are of major importance to agricultural adjustment and to policy. This paper examines the main issues involved in achieving a more adequate understanding of the tax treatments applied to agriculture.

Recently, e-prop was proposed as a causal, local, and efficient practical alternative to these algorithms, providing an approximation of the exact gradient by radically pruning the recurrent dependencies carried over time. Here, we derive RTRL from BPTT using a detailed notation bringing intuition and clarification to how they are connected. Furthermore, we frame e-prop within in the picture, formalising what it approximates. Finally, we derive a family of algorithms of which e-prop is a special case.

description: Markov processes with stochastic resetting towards the origin generically converge towards non-equilibrium steady-states. Long dynamical trajectories can be thus analyzed via the large deviations at Level 2.5 for the joint probability of the empirical density and the empirical flows, or via the large deviations of semi-Markov processes for the empirical density of excursions between consecutive resets. The large deviations properties of general time-additive observables involving the position and the increments of the dynamical trajectory are then analyzed in terms of the appropriate Markov tilted processes and of the corresponding conditioned processes obtained via the generalization of Doob's h-transform. This general formalism is described in detail for the three possible frameworks, namely discrete-time/discrete-space Markov chains, continuous-time/discrete-space Markov jump processes and continuous-time/continuous-space diffusion processes, and is illustrated with explicit results for the Sisyphus Random Walk and its variants, when the reset probabilities or reset rates are space-dependent.

description: Worldwide production of biodiesel is growing at a rapid pace. Arguably, the European Union (EU) is the global leader in biodiesel production, but the United States has recently expanded its production. The growth of the biodiesel industry in both regions has been fueled by a series of government-provided financial incentives. However, the timing of the growth and incentive provisions, the nature of the main incentives, and the market conditions differ across regions. This article provides a comparative analysis of the EU and U.S. biodiesel industries, highlighting market and policy aspects that are leading to a rapid but distinct growth.
Sourced Friedmann equations with holographic energy density

Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We reexamine cosmological applications of the holographic energy density in the framework of sourced Friedmann equations. This framework is suitable because it can accommodate a macroscopic interaction between holographic and ordinary matter naturally. In the case that the holographic energy density decays into dust matter, we propose a microscopic mechanism to generate an accelerating phase. Actually, the cosmic anti-friction arisen from the decay process induces acceleration. For examples, we introduce two IR cutoffs of Hubble horizon and future event horizon to test this framework. As a result, it is shown that the equations of state for the holographic energy density are determined to be the same negative constants as those for the dust matter.

Effects of medium-induced $ρ-ω$ meson mixing on the equation of state in isospin-asymmetric nuclear matter

description: We reexamine effects of the $ρ-ω$ meson mixing mediated by nucleon polarizations on the symmetry energy in isospin-asymmetric nuclear matter. Taking into account the rearrangement term neglected in previous studies by others, we evaluate the $ρ-ω$ mixing angle in a novel way within the Relativistic Mean-Field Models with and without chiral limits. It is found that the symmetry energy is significantly softened at high densities contrary to the finding in earlier studies. As the first step of going beyond the lowest-order calculations, we also solve the RPA equation for the $ρ-ω$ mixing. In this case, it is found that the symmetry energy is not only significantly softened by the $ρ-ω$ mixing at supra-saturation densities, similar to the lowest-order $ρ-ω$ mixing, but interestingly also softened at subsaturation densities. In addition, the softening of the symmetry energy at subsaturation densities can be partly suppressed by the nonlinear self-interaction of the $σ$ meson.

Too Smart for Their Own Good! Complexity, Capacity and Credence in Trade Negotiations

description: Multilateral trade negotiations are, by design, becoming increasingly complex. The current degree of complexity limits the ability to assess the effects of a potential agreement and inhibits the transparency needed to reach an agreement. Despite the considerable recent efforts at capacity building in developing countries, the additional complexity has outstripped the ability to build capacity. This article draws upon New Institutional Economics to examine the effects of complexity on trade negotiations. The conclusion is that the rational decision of many countries may be to opt for no agreement.

Then we introduce the resulting notions of the diffeological Fisher distance, the diffeological Hausdorff--Jeffrey measure and explain their role in classical and Bayesian nonparametric estimation problems in statistics.

description: The North China Plain is the country's granary: most of wheat and maize is supplied by this region in the northeast of China. Intensity of agricultural production has risen sharply in the last decades and the negative environmental effects like water scarcity, salinization and nitrate contamination have been widely acknowledged. In the wake of the country's rapid economic development it becomes at the same time more and more urgent to narrow the gap between the well-being of the urban and rural population. In order to better understand the paths that lead to this present dilemma, this paper provides a historical overview of the development of the land and water markets and the rural financial system. It highlights the linkages and reciprocal restraints between these three sectors and gives some conclusions and policy recommendations on how to proceed in order to further a more sustainable development in the North China Plain. Apart from literature review, data from an original farm household survey, conducted by the authors, is used to substantiate the arguments put forth in this paper.

Ring Exchange and Phase Separation in the Two-dimensional Boson Hubbard model

description: We present Quantum Monte Carlo simulations of the soft-core bosonic Hubbard model with a ring exchange term K. For values of K which exceed roughly half the on-site repulsion U, the density is a non-monotonic function of the chemical potential, indicating that the system has a tendency to phase separate. This behavior is confirmed by an examination of the density-density structure factor and real space images of the boson configurations. Adding a near-neighbor repulsion can compete with phase separation, but still does not give rise to a stable normal Bose liquid.

Runtime Analysis for the NSGA-II: Provable Speed-Ups From Crossover

description: Very recently, the first mathematical runtime analyses for the NSGA-II, the most common multi-objective evolutionary algorithm, have been conducted. Continuing this research direction, we prove that the NSGA-II optimizes the OneJumpZeroJump benchmark asymptotically faster when crossover is employed. Together with a parallel independent work by Dang, Opris, Salehi, and Sudholt, this is the first time such an advantage of crossover is proven for the NSGA-II. Our arguments can be transferred to single-objective optimization. They then prove that crossover can speed up the $(μ+1)$ genetic algorithm in a different way and more pronounced than known before. Our experiments confirm the added value of crossover and show that the observed advantages are even larger than what our proofs can guarantee.

Estimate of the Hadronic Production of the Doubly Charmed Baryon $Ξ_{cc}$ under GM-VFN Scheme

description: Hadronic production of the doubly charmed baryon $Ξ_{cc}$ ($Ξ^{++}_{cc}$ and $Ξ^{+}_{cc}$) is investigated under the general-mass variable-flavor-number (GM-VFN) scheme. The gluon-gluon fusion mechanism and the intrinsic charm mechanisms, i.e. via the sub-processes $g+g\to(cc)[^3S_1]_{\bar 3}+\bar{c}+\bar{c}$, $g+g\to(cc)[^1S_0]_6+\bar{c}+\bar{c}$; $g+c\to (cc)[^3S_1]_{\bar 3}+\bar{c}$, $g+c\to (cc)[^1S_0]_6+\bar{c}$ and $c+c\to (cc)[^3S_1]_{\bar 3}+g$, $c+c\to (cc)[^1S_0]_6+g$, are taken into account in the investigation, where $(cc)[^3S_1]_{\bar 3}$ (in color {\bf $\bar 3$}) and $(cc)[^1S_0]_6$ (in color {\bf 6}) are two possible $S$-wave configurations of the doubly charmed diquark pair $(cc)$ inside the baryon $Ξ_{cc}$. Numerical results for the production at hadornic colliders LHC and TEVATRON show that both the contributions from the doubly charmed diquark pairs $(cc)[^1S_0]_6$ and $(cc)[^3S_1]_{\bar 3}$ are sizable with the assumption that the two NRQCD matrix elements are equal, and the total contributions from the `intrinsic' charm mechanisms are bigger than those of the gluon-gluon fusion mechanism. For the production in the region of small transverse-momentum $p_t$, the intrinsic mechanisms are dominant over the gluon-gluon fusion mechanism and they can raise the theoretical prediction of the $Ξ_{cc}$ by almost one order.
