Hard pion and prompt photon at RHIC, from single to double inclusive production
Creators: name: Arleo, Francois
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Single pion and prompt photon large transverse momentum spectra in p-p and Au-Au collisions are computed in perturbative QCD at RHIC energy, s^1/2 = 200 GeV. Next-to-leading order calculations are discussed and compared with p-p scattering data. Subsequently, quenching factors are computed to leading order for both pions and photons within the same energy loss model. The good agreement with PHENIX preliminary data allows for a lower estimate of the energy density reached in central Au-Au collisions, epsilon > 10 GeV/fm^3. Double inclusive photon-pion production in p-p and Au-Au collisions is then addressed. Next-to-leading order corrections prove rather small in p-p scattering. In Au-Au collisions, the quenching of momentum-correlation spectra is seen to be sensitive to parton energy loss processes, which would help to understand how the fragmentation dynamics is modified in nuclear collisions at RHIC.

subject: Seattle

description: World conflicts largely stem from a lack of understanding among people. Ignorance between cultures often breeds separation and, at times, hostility. In response to this lack of interaction between people, this thesis explores the potential that exists at nodes of convergence. The international airport provides a lens for this exploration. At its core, the airport terminal is a mechanism for movement. Its purpose has traditionally been to capture, filter, and organize people as they progress towards their destination. This thesis takes advantage of the condition of the airport to promote an agenda of fostering human interaction. The design will focus on the journey of the individual as a means of enhancing the collective experience.

description: What concepts about movement & the body can architects learn from the discipline of dance?  By analyzing architecture through the lens of dance, much is to be learned from the way bodies move through and interact with space.  I believe dancers are more in-tune with their bodies and context.  Through a series of dance and movement related exercises, I will demonstrate how analyzing choreography in architecture can lead to a better understanding of human-spatial relationships.  These findings will influence design in order to heighten architectural experiences.  This thesis serves as a model for cross-disciplinary work in the dance and architecture fields; it uses architecture as a tool to improve the well-being of the body

description: A two-stage approach is used to estimate sensitivity of corn, wheat, and soybean yields to changes in prices and land idled. Estimated elasticity of demand for fertilizer per acre with respect to expected output price equals 0.47, 0.10, and 0.82 for corn, wheat, and soybeans. Upper estimates of the elasticity of yield with respect to fertilizer equals +0.58, +0.29, and +0.16 for corn, wheat, and soybeans. Yields are found to be quite insensitive to price changes. Fertilizer demands and yields are insensitive to land idled under farm programs.

description: We present the design and characterization of a cryogenic phonon-sensitive 1-gram Si detector exploiting the Neganov-Trofimov-Luke effect to detect single-charge excitations. This device achieved 2.65(2)~eV phonon energy resolution when operated without a voltage bias across the crystal and a corresponding charge resolution of 0.03 electron-hole pairs at 100~V bias. With a continuous-readout data acquisition system and an offline optimum-filter trigger, we obtain a 9.2~eV threshold with a trigger rate of the order of 20~Hz. The detector's energy scale is calibrated up to 120~keV using an energy estimator based on the pulse area. The high performance of this device allows its application to different fields where excellent energy resolution, low threshold, and large dynamic range are required, including dark matter searches, precision measurements of coherent neutrino-nucleus scattering, and ionization yield measurements.

description: We present and discuss a detailed derivation of a new analytical method that systematically improves the convergence of path integrals of a generic $N$-fold discretized theory. We develop an explicit procedure for calculating a set of effective actions $S^{(p)}$, for $p=1,2,3,...$ which have the property that they lead to the same continuum amplitudes as the starting action, but that converge to that continuum limit ever faster. Discretized amplitudes calculated using the $p$ level effective action differ from the continuum limit by a term of order $1/N^p$. We obtain explicit expressions for the effective actions for levels $p\le 9$. We end by analyzing the speedup of Monte Carlo simulations of two different models: an anharmonic oscillator with quartic coupling and a particle in a modified Pöschl-Teller potential.

description: Whether or not privatization facilitates rural development depends upon what rural development means. In practice, rural development often is the result of a struggle between rent defenders and rent seekers. A positivist concept of rural development is proposed, and the institutions of public choice are examined to determine how they might influence privatization decisions. The conclusion is that whether or not privatization improves efficiency of adjustment in rural economies depends upon the specifics of political deals required to achieve a particular act of privatization.

Subjects: subject: Architecture

description: The car oriented society in the United Sates causes a lack for the pedestrian, air pollution, traffic congestion and an increased cost for transportation. The suburban sprawl and underdeveloped suburban areas contributes to monotony.

There is a need for a thorough rethinking of the suburban areas, especially near light rail and transit oriented development opportunity zones.  This thesis evaluates the Prince George Plaza area, to show how much more design and urban oriented space thinking could help further, in essence a more pedestrian friendly precinct with mixed use and higher density development, along with significant parking and infrastructure transforming can make a dramatic difference.

The thesis explores has three primary scales of concern: a master plan of the context, a multi-block precinct within the master plan, and a proposed  building within that precinct. With creative design thinking and a rigorous “pay forward” approach, I will seek to demonstrate how design thinking can provide transformative promise and development returns to a compromised nearby neighborhood.

description: The international PEN collaboration aims to obtain the branching ratio for the pion electronic decay $π^+ \to e^+ν_e(γ)$, aka $π_{e2}$, to a relative precision of $5\times 10^{-4}$ or better. The PEN apparatus comprises a number of detection systems, all contributing vital information to the PEN event reconstruction. This paper discusses the design, performance, and Monte Carlo simulation of the mini time projection chamber (mTPC) used for pion, muon, and positron beam particle tracking. We also review the use of the extracted trajectory coordinates in the analysis, in particular in constructing observables critical for discriminating background processes, and in maximizing the fiducial volume of the target in which decay event vertices can be accepted for branching ratio extraction without introducing bias.

description: Public space is vital to urban society because it lies at the center of social and cultural life, however today the internet acts as a new centrality where interaction and socialization occur in a new invisible setting. Today both physical and digital public space serve as a vital interface for civic engagement and public participation, yet there is much content that often only remains significant on the internet. This thesis seeks to both strengthen the significance of our online public interactions and enliven the urban public realm by translating digital cultures into the urban environment, giving content the ability to flow between both worlds. This hypothesis will be tested through the redesign of Pershing Square in Downtown, Los Angeles, CA.

It has been shown that the data can be reproduced reasonably well assuming a deconfined state of thermalized quarks and gluons with initial temperature more than the transition temperature for deconfinement inferred from lattice QCD. The value of the initial temperature depends on the equation of state of the evolving matter. The sensitivities of the results on various input parameters have been studied. The effects of the modifications of hadronic properties at non-zero temperature have been discussed.

FOUR DECADES OF INVESTIGATING RACE AND POVERTY

The Chicago Reporter is a small nonprofit news organization founded in 1972 to use investigative and data-driven journalism to uncover and highlight racial and economic disparities in Chicago. It is written for local elites who can implement reforms. Its stories have prompted changes, and it has trained a diverse group of journalists in the process. But it never has built a broad readership or developed a business plan that doesn’t rely on charity. The question of this thesis is: How has the Chicago Reporter survived for four decades? A review of its history and interviews with its publishers found the Reporter still exists because it has a base at a stable nonprofit, and its reporting on race and poverty draws support from a core group of funders, leaders, and academics. Yet its singular focus has limited expansion, and its recent move to an all-digital operation poses challenges for its future.
Spatial Distribution of Forest Ecosystem Service Benefits in Germany: A Multiple Benefit-Transfer Model

description: We investigate the economic benefits of fundamental forest ecosystem services (FES) for the population in Germany at national level in monetary terms and estimate the spatial distribution of these benefits at county level. Specifically, we consider the benefits of timber production, of global climate protection due to carbon sequestration, of recreation for local residents, and of services for nature protection and landscape amenity. Combining information from official statistics and data from valuation studies that are compatible with economic demand theory, we identify spatial drivers of FES benefits and derive generic valuation functions for each of the services. Using a Geographic Information System, these valuation functions are applied to the conditions in the Local Administrative Units (municipalities), resulting in Benefit Function Transfer estimates for each service and each municipality. Afterwards, results are aggregated to NUTS-3 level (counties) and mapped. Aggregate annual benefits of timber production to society as a whole, of climate protection and of recreation services together exceed the ten billion Euro mark—far more than what is reflected in market statistics. Scenarios illustrate the potential for enhancing nature protection benefits particularly by restoring forest biodiversity, as measured by an avifaunistic indicator. The spatial analysis reveals distinct distributional patterns for each of the services. We conclude that a spatially explicit valuation for an entire country is possible even with limited data, which can help policy makers improve the institutional setting in a way that the protection and use of the forests become more sustainable and efficient. After pointing at several caveats, we finally suggest various possibilities for further model development.

description: Silicon quantum dot qubits must contend with low-lying valley excited states which are sensitive functions of the quantum well heterostructure and disorder; quantifying and maximizing the energies of these states are critical to improving device performance. We describe a spectroscopic method for probing excited states in isolated Si/SiGe double quantum dots using standard baseband pulsing techniques, easing the extraction of energy spectra in multiple-dot devices. We use this method to measure dozens of valley excited state energies spanning multiple wafers, quantum dots, and orbital states, crucial for evaluating the dependence of valley splitting on quantum well width and other epitaxial conditions. Our results suggest that narrower wells can be beneficial for improving valley splittings, but this effect can be confounded by variations in growth and fabrication conditions. These results underscore the importance of valley splitting measurements for guiding the development of Si qubits.

description: Four-dimensional $\mathcal{N}=4$ supersymmetric Yang-Mills theory, at a point on the Coulomb branch where $SU(N)$ gauge symmetry is spontaneously broken to $SU(N-1)\times U(1)$, admits BPS solitons describing a spherical shell of electric and/or magnetic charges enclosing a region of unbroken gauge symmetry. These solitons have been proposed as gauge theory models for certain features of asymptotically flat extremal black holes. In the 't Hooft large $N$ limit with large 't Hooft coupling, these solitons are holographically dual to certain probe D3-branes in the $AdS_5 \times S^5$ solution of type IIB supergravity. By studying linearised perturbations of these D3-branes, we show that the solitons support quasinormal modes with a spectrum of frequencies sharing both qualitative and quantitative features with asymptotically flat extremal black holes.

An explicit scheme for multifluid magnetohydrodynamics

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: When modeling astrophysical fluid flows, it is often appropriate to discard the canonical magnetohydrodynamic approximation thereby freeing the magnetic field to diffuse with respect to the bulk velocity field. As a consequence, however, the induction equation can become problematic to solve via standard explicit techniques. In particular, the Hall diffusion term admits fast-moving whistler waves which can impose a vanishing timestep limit. Within an explicit differencing framework, a multifluid scheme for weakly ionised plasmas is presented which relies upon a new approach to integrating the induction equation efficiently. The first component of this approach is a relatively unknown method of accelerating the integration of parabolic systems by enforcing stability over large compound timesteps rather than over each of the constituent substeps. This method, Super Time Stepping, proves to be very effective in applying a part of the Hall term up to a known critical value. The excess of the Hall term above this critical value is then included via a new scheme for pure Hall diffusion.

description: This thesis will explore new alchemies of architecture, urban planning and real estate development to remedy failing American malls and their urban contexts. The focus of this thesis is to build a toolbox of urban, architecture, and landscape strategies to diagnose and heal malls in economically distressed areas. As people move back into cities, malls are becoming vestiges of suburban sprawl and an ethos that has failed us. Once numbering roughly 1,500 nationwide, the number of regional malls is projected to dwindle to little over 300 in the coming decades. With the national decline of the specialized mall format, there is an opportunity to hypothesize about the future of these failing malls. I will investigate specialty and commodity retail to understand the history of the retail industry and its effect on our urban evolution. By studying the rise of shopping malls and the isolation of retail in America I will make a case for more appropriate place-making that encourages more balanced, sustainable and resilient urbanism. These strategies will be applied to Marley Station Mall, located in Anne Arundel County, Maryland.

description: We investigate the diffusive shock acceleration in the presence of the non-resonant streaming instability introduced by Bell (2004). The numerical MHD simulations of the magnetic field amplification combined with the analytical treatment of cosmic ray acceleration permit us to calculate the maximum energy of particles accelerated by high-velocity supernova shocks. The estimates for Cas A, Kepler, SN1006, and Tycho historical supernova remnants are given. We also found that the amplified magnetic field is preferentially oriented perpendicular to the shock front downstream of the fast shock. This explains the origin of the radial magnetic fields observed in young supernova remnants.

description: The accuracy of quantum dynamics simulation is usually measured by the error of the unitary evolution operator in the operator norm, which in turn depends on certain norm of the Hamiltonian. For unbounded operators, after suitable discretization, the norm of the Hamiltonian can be very large, which significantly increases the simulation cost. However, the operator norm measures the worst-case error of the quantum simulation, while practical simulation concerns the error with respect to a given initial vector at hand. We demonstrate that under suitable assumptions of the Hamiltonian and the initial vector, if the error is measured in terms of the vector norm, the computational cost may not increase at all as the norm of the Hamiltonian increases using Trotter type methods. In this sense, our result outperforms all previous error bounds in the quantum simulation literature. Our result extends that of [Jahnke, Lubich, BIT Numer. Math. 2000] to the time-dependent setting. We also clarify the existence and the importance of commutator scalings of Trotter and generalized Trotter methods for time-dependent Hamiltonian simulations.

description: A computational linear stability analysis of spiral waves in a reaction-diffusion equation is performed on large disks. As the disk radius R increases, eigenvalue spectra converge to the absolute spectrum predicted by Sandstede and Scheel. The convergence rate is consistent with 1/R, except possibly near the edge of the spectrum. Eigenfunctions computed on large disks are compared with predicted exponential forms. Away from the edge of the absolute spectrum the agreement is excellent, while near the edge computed eigenfunctions deviate from predictions, probably due to finite-size effects. In addition to eigenvalues associated with the absolute spectrum, computations reveal point eigenvalues. The point eigenvalues and associated eigenfunctions responsible for both core and far-field breakup of spiral waves are shown.

description: More than 1,400 golf facilities in the United States have closed permanently since 2001, part of a natural supply correction, as well as a reflection of the fluctuating interest in the game. Through their design, golf courses inherently preserve a singular form of open, green space. In their most dynamic form, they are culturally integral landscapes with vibrant ecosystems that provide wildlife habitat. They represent some of the largest ‘undeveloped’ spaces in United States’ cities. Each golf course closing represents a single patch of many that, with sound design, could be woven together through a common purpose, like a landscape quilt. Through a site-specific analysis, the resulting design proposal for Wakefield Wildlife Reservation is a new type of landscape for the city of Westminster, MD, serving as an example for future projects. It will provide valuable habitat and dynamic recreational space, while expressing site and regional history.

We show how such signatures can be established through a heavy Higgs portal in the presence of both leptonic and hadronic decays of the sneutrinos. We finally illustrate how the Yukawa parameters of the latter can be extracted from fitting kinematical quantities pertaining to the corresponding two displaced vertices, thereby characterising the dynamics of the underlying mechanism of neutrino mass generation. We show our numerical results for the case of both the current and High-Luminosity LHC.

description: The town of Orbetello, located near the ancient port of Cosa in Tuscany, has, for many years, benefited from the seasonal influx of domestic tourism.  However, uneven expansion in the town’s industrial sector, as well as seasonal overuse of the land’s natural resources, has negatively impacted the lagoon and its delicate ecosystem. Most recently, in the summer of 2015, over two hundred tons of fish were lost overnight due to increasing temperatures, lack of oxygen, and most likely, poor water-interchange between the lagoon and the Tyrrhenian . The continuous loss of this precious ecological and economic asset is, of course, devastating for an economy so reliant on its harvest.

With these extremely delicate natural, economic, and historical conditions, the need for responsive design becomes increasingly important.  The focus of this thesis will be on the urban and architectural design interventions that could aid the Orbetello region, through the reclaiming of local ecology, reuse of historic structures, and linking of urban zones in the downtown area. This document will serve as a study on how the models of pescatourism and ecotourism can be applied to the fishing industry, both as a regenerative tools, and as an economic devices.

description: The gravitational waves (GW) emitted during the coalescence of supermassive black holes (SMBHs) in the mass range 10^4-10^7 M_sun will be detectable out to high redshifts with LISA. We calculate the size and orientation of the three-dimensional error ellipse in solid angle and redshift within which the LISA event could be localized using the GW signatures alone. We take into account uncertainties in LISA's measurements of the luminosity distance and direction to the source, in the background cosmology, in weak gravitational lensing magnification due to inhomogeneities along the line of sight, and potential source peculiar velocities. We find that weak lensing errors exceed other sources of uncertainties by nearly an order of magnitude. Under the plausible assumption that BH mergers are accompanied by gas accretion leading to Eddington-limited quasar activity, we then compute the number of quasars that would be found in a typical LISA error volume, as a function of BH mass and redshift. We find that low redshifts offer the best opportunities to identify quasar counterparts to cosmological standard sirens, and that the LISA error volume will typically contain a single near-Eddington quasar at z=1. This will allow a straightforward test of the hypothesis that BH mergers are accompanied by bright quasar activity and, if the hypothesis proves correct, will guarantee the identification of a unique quasar counterpart. This would yield unprecedented tests of the physics of SMBH accretion, and offer an alternative method to precisely constrain cosmological parameters [abridged].

description: Reaction-diffusion waves have long been used to describe the growth and spread of populations undergoing a spatial range expansion. Such waves are generally classed as either pulled, where the dynamics are driven by the very tip of the front and stochastic fluctuations are high, or pushed, where cooperation in growth or dispersal results in a bulk-driven wave in which fluctuations are suppressed. These concepts have been well studied experimentally in populations where the cooperation leads to a density-dependent growth rate. By contrast, relatively little is known about experimental populations that exhibit density-dependent dispersal. Using bacteriophage T7 as a test organism, we present novel experimental measurements that demonstrate that the diffusion of phage T7, in a lawn of host E. coli, is hindered by steric interactions with host bacteria cells. The coupling between host density, phage dispersal and cell lysis caused by viral infection results in an effective density-dependent diffusion coefficient akin to cooperative behavior. Using a system of reaction-diffusion equations, we show that this effect can result in a transition from a pulled to pushed expansion. Moreover, we find that a second, independent density-dependent effect on phage dispersal spontaneously emerges as a result of the viral incubation period, during which phage is trapped inside the host unable to disperse. Additional stochastic agent-based simulations reveal that lysis time dramatically affects the rate of diversity loss in viral expansions. Taken together, our results indicate both that bacteriophage can be used as a controllable laboratory population to investigate the impact of density-dependent dispersal on evolution, and that the genetic diversity and adaptability of expanding viral populations could be much greater than is currently assumed.

description: We present the results of a recently conducted mm-experiment at the IRAM 30m telescope. We searched in two QSO hosts for the HCN(J=1-0) line emission tracing the dense regions of gas. Our goal is to probe the HCN-CO line ratio in QSO hosts for the first time and to compare the results with recent findings of quiescent galaxies. These findings indicate a strong correlation between the star formation efficiency and the HCN-CO line ratio over several orders of magnitudes in infrared luminosities.

description: A correlation between the angle of multiple scattering and the ionization energy loss for relativistic electrons in an amorphous medium is computed by solving the combined transport equation. The correlation is found to be the most pronounced at deflection angles larger than typical, reflecting the underlying single-scattering kinematical correlation, but is also sizable at typical deflection angles, where the width of the angular distribution increases with the increase of the energy loss. The mean energy loss as a function of the deflection angle is calculated. It grows quadratically both at small and at large angles, but the proportionality coefficient at large angles is greater than at small ones.

description: We have studied the magnetoresistance (TMR) of tunnel junctions with electrodes of La2/3Sr1/3MnO3 and we show how the variation of the conductance and TMR with the bias voltage can be exploited to obtain a precise information on the spin and energy dependence of the density of states. Our analysis leads to a quantitative description of the band structure of La2/3Sr1/3MnO3 and allows the determination of the gap delta between the Fermi level and the bottom of the t2g minority spin band, in good agreement with data from spin-polarized inverse photoemission experiments. This shows the potential of magnetic tunnel junctions with half-metallic electrodes for spin-resolved spectroscopic studies.

description: We study the effects of a modest V+A admixture strength in $b\tou$ current in the decay $B \toρl ν$. We have shown that the decay rate, lepton forward-backward distribution asymmetry $A_{FB}$ and polarization ratio are sensitive to the admixture. Future experimental studies of the decay at BaBar and BELLE could clarify the chirality of $b\to u$ current and might reveal hints for New Physics with right-handed quark currents.

description: We discuss a computer implementation of a recursive formula to calculate correlation functions of descendant states in two-dimensional CFT. This allows us to obtain any $N$-point function of vacuum descendants, or to express the correlator as a differential operator acting on the respective primary correlator in case of non-vacuum descendants. With this tool at hand, we then study some entanglement and distinguishability measures between descendant states, namely the Rényi entropy, trace square distance and sandwiched Rényi divergence. Our results provide a test of the conjectured Rényi QNEC and new tools to analyse the holographic description of descendant states at large $c$.

Channel noise and synchronization in excitable membranes

description: Using a stochastic generalization of the Hodgkin–Huxley model, we consider the influence of intrinsic channel noise on the synchronization between the spiking activity of the excitable membrane and an externally applied periodic signal. For small patches, i.e., when the channel noise dominates the excitable dynamics, we find the phenomenon of intrinsic coherence resonance. In this case, the relatively regular spiking behavior is practically independent of the applied external driving; therefore no synchronization occurs. Synchronization takes place, however, only for sufficiently large ion channel assemblies. The neuronal signal processing is thus likely rooted in the collective properties of optimally large assemblies of ion channels.
