description: Planckian Interacting Dark Matter (PIDM) is a minimal scenario of dark matter assuming only gravitational interactions with the standard model and with only one free parameter, the PIDM mass. PIDM can be successfully produced by gravitational scattering in the thermal plasma of the Standard Model sector after inflation in the PIDM mass range from TeV up to the GUT scale, if the reheating temperature is sufficiently high. The minimal assumption of a GUT scale PIDM mass can be tested in the future by measurements of the primordial tensor-to-scalar ratio. While large primordial tensor modes would be in tension with the QCD axion as dark matter in a large mass range, it would favour the PIDM as a minimal alternative to WIMPs. Here we generalise the previously studied scalar PIDM scenario to the case of fermion, vector and tensor PIDM scenarios, and show that the phenomenology is nearly identical, independent of the spin of the PIDM. We also consider the specific realisation of the PIDM as the Kaluza Klein excitation of the graviton in orbifold compactifications of string theory, as well as in models of monodromy inflation and in Higgs inflation. Finally we discuss the possibility of indirect detection of PIDM through non-perturbative decay.

The emergence of the galactic stellar mass function from a non-universal IMF in clusters

description: We investigate how a single generation galactic mass function (SGMF) depends on the existence of variations in the initial stellar mass functions (IMF) of stellar clusters. We show that cluster-to-cluster variations of the IMF lead to a multicomponent SGMF where each component in a given mass range can be described by a distinct power-law function. We also show that a dispersion of $\approx 0.3$ M$_{\odot}$ in the characteristic mass of the IMF, as observed for young Galactic clusters, leads to a low mass slope of the SGMF that matches the observed Galactic stellar mass function even when the IMFs in the low mass end of individual clusters are much steeper.

description: We have simulated the SU(4) lattice gauge theory coupled to dynamical fermions in the fundamental and two-index antisymmetric (sextet) representations simultaneously. Such theories arise naturally in the context of composite Higgs models that include a partially composite top quark. We describe the low-lying meson spectrum of the theory and fit the pseudoscalar masses and decay constants to chiral perturbation theory. We infer as well the mass and decay constant of the Goldstone boson corresponding to the non-anomalous U(1) symmetry of the model. Our results are broadly consistent with large-Nc scaling and vector-meson dominance.

B_d and B_s mixing: mass and width differences and CP violation
Creators: name: Nierste, Ulrich
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: B-B-bar mixing involves three physical parameters: the magnitudes of the off-diagonal elements of the mass and decay matrices and their relative phase. They are related to the mass and width differences between the mass eigenstates and to the CP asymmetry in flavour-specific decays, a_fs. Introducing a new operator basis I present new, more precise theory predictions for the width differences in the B_s and B_d systems: in the Standard Model one finds Delta Gamma_s = 0.088 +/- 0.017 ps^{-1} and Delta Gamma_d = (26.7 +5.8/-6.5) * 10^{-4} ps^{-1}. Updates of the mass differences Delta M_d and Delta M_s and of a_{fs}^d and a_{fs}^s are also presented. Then I discuss how various present and future measurements can be combined to constrain new physics. The extraction of a new CP phase phi_s^Delta from data on a_{fs}^s also profits from our new operator basis. Confronting our new formulae with D0 data we find that sin phi_s^Delta deviates from zero by 2 sigma.

The Correlation Function of Rich Clusters of Galaxies in CDM-like Models

description: We use ensembles of high-resolution CDM simulations to investigate the shape and amplitude of the two point correlation function of rich clusters. The standard scale-invariant CDM model with $Ω=1$ provides a poor description of the clustering measured from the APM rich cluster redshift survey, which is better fitted by models with more power at large scales. The amplitudes of the rich cluster correlation functions measured from our models depend weakly on cluster richness. Analytic calculations of the clustering of peaks in a Gaussian density field overestimate the amplitude of the N-body cluster correlation functions, but reproduce qualitatively the weak trend with cluster richness. Our results suggest that the high amplitude measured for the correlation function of richness class $R \geq 2$ Abell clusters is either an artefact arising from incompleteness in the Abell catalogue, or an indication that the density perturbations in the early universe were very non-Gaussian.

description: Invasive species can indirectly affect native species by modifying parasite–host dynamics and disease occurrence. This scenario applies to European coastal waters where the invasive Pacific oyster (Magallana gigas) co-introduced the parasitic copepod Mytilicola orientalis that spills over to native blue mussels (Mytilus edulis) and other native bivalves. In this study, we investigated the impact of M. orientalis infections on blue mussels by conducting laboratory experiments using controlled infections with larval stages of the parasitic copepod. As the impact of infections is likely to depend on the mussels’ food availability, we also tested whether potential adverse effects of infection on mussels intensify under low food conditions. Blue mussels that were experimentally infected with juvenile M. orientalis had a significantly lower body condition (11–13%) compared with uninfected mussels after nine weeks of infection. However, naturally infected mussels from a mixed mussel and oyster bed did not significantly differ in body condition compared with uninfected mussels. Contrary to effects on mussel condition, we did not find an effect of experimental infections on clearance rates, shell growth or survival of blue mussels and no clear sign of exacerbating effects of food limitation. Our study illustrates that invasive species can indirectly affect native species via parasite co-introductions and parasite spillover. The results of this study call for the integration of such parasite-mediated indirect effects of invasions in impact assessments of invasive species.
La scuola di Astra Zarina a Civita di Bagnoregio. Una sfida contro l’abbandono
Creators: name: Attili, Giovanni

Year: 2019

description: The residential school imagined by Astra Zarina in Civita di Bagnoregio, in the mid seventies, has been a collective learning laboratory that, for more than 30 years, led to a massive knowledge production on the territorial fragility of Civita and, at the same time, to identify unprecedented planning visions. Most of all, it contributed to a revitalisation of a village that was on the brim of social atrophy. In those years Civita, in fact, was a rural village that had been threateningly abandoned because of the industrialisation processes and the consequent abandonment of countryside, primary source for the survival of its community. The political and sociological imagination of Astra and the active involvement of the dwellers who had not left the town, progressively, brought Civita into a new life cycle.

description: We examine the 10\m\ emission of the central regions of 281 spiral galaxies, after having compiled all ground-based, small-aperture ($\sim$5") broad-band photometric observations at ł$\sim$10\m\ (N magnitudes) published in the literature. We evaluate the compactness of the $\sim$10\m\ emission of galaxy nuclei by comparing these small-beam measures with the large-beam IRAS 12\m\ fluxes. In the analysis of different subsets of objects, we apply survival analysis techniques in order to exploit the information contained in ``censored'' data (i.e., upper limits on the fluxes). Seyferts are found to contain the most powerful nuclear sources of mid-infrared emission, which in $\sim$1/3 of cases provide the bulk of the emission of the entire galaxy; thus, mid-infrared emission in the outer disc regions is not uncommon in Seyferts. The 10\m\ emission of Seyferts appears to be unrelated to their X-ray emission. HII region-like nuclei are stronger mid-infrared sources than normal nuclei and LINER nuclei (whose level of emission is not distinguishable from that of normal nuclei). Interacting objects have, on average, greater 10\m\ luminosities than non-interacting ones and exhibit more compact emission. Early-type spirals have stronger and more compact 10\m\ emission than late-type ones. Barred spirals are brighter at $\sim$10\m\ than unbarred systems, essentially because they more frequently contain HII region-like nuclei. The results of our detailed comparison between the behaviour of various categories of objects stress that the 10\m\ emission of spiral nuclei is closely linked to the (predominantly non-thermal synchrotron) radio

description: The determined abundances of primordial $^4He$ and $^7Li$ provide a basis with which to test the standard model of big bang nucleosynthesis in conjunction with the other two light element isotopes $D$ and $^3He$, also produced in the big bang. Overall, consistency in the standard big bang nucleosynthesis model is best achieved for a baryon-to-photon ratio of typically $3 \times 10^{-10}$ for which the primordial value of $D$ is five times greater than the present observed abundance and about three times greater than the pre-solar value. We consider various models for the chemical evolution of the Galaxy to test the feasibility for the destruction of D without the overproduction of $^3He$ and overall metallicity. Models which are capable of achieving this goal include ones with a star formation rate proportional to the gas mass fraction or an exponentially decreasing star formation rate. We discuss the effect of parameters that govern the initial mass function and of surviving fractions of $^3He$ in stars between one and three solar masses.

description: We explore the sensitivity of weak lensing observables to the expansion history of the universe and to the growth of cosmic structures, as well as the relative contribution of both effects to constraining cosmological parameters. We utilize ray-tracing dark-matter-only N-body simulations and validate our technique by comparing our results for the convergence power spectrum with analytic results from past studies. We then extend our analysis to non-Gaussian observables which cannot be easily treated analytically. We study the convergence (equilateral) bispectrum and two topological observables, lensing peaks and Minkowski functionals, focusing on their sensitivity to the matter density $Ω_m$ and the dark energy equation of state $w$. We find that a cancelation between the geometry and growth effects is a common feature for all observables, and exists at the map level. It weakens the overall sensitivity by up to a factor of 3 and 1.5 for $w$ and $Ω_m$, respectively, with the bispectrum worst affected. However, combining geometry and growth information alleviates the degeneracy between $Ω_m$ and $w$ from either effect alone. As a result, the magnitude of marginalized errors remain similar to those obtained from growth-only effects, but with the correlation between the two parameters switching sign. These results shed light on the origin of cosmology-sensitivity of non-Gaussian statistics, and should be useful in optimizing combinations of observables.

Positive parity pentaquark towers in large Nc QCD

description: We construct the complete set of positive parity pentaquarks, which correspond in the quark model to {\bar s} q^{Nc+1} states with one unit of orbital angular momentum L=1. In the large Nc limit they fall into the K=1/2 and K=3/2 irreps (towers) of the contracted SU(4)c symmetry. We derive predictions for the mass spectrum and the axial couplings of these states at leading order in 1/Nc. The strong decay width of the lowest-lying positive parity exotic state is of order O(1/Nc), such that this state is narrow in the large Nc limit. Replacing the antiquark with a heavy antiquark {\bar Q} q^{Nc+1}, the two towers become degenerate, split only by O(1/mQ) hyperfine interactions. We obtain predictions for the strong decay widths of heavy pentaquarks to ordinary baryons and heavy H(*)_{\bar Q} mesons at leading order in 1/Nc and 1/mQ.

Le nuove sfide tecnologiche e le principali risposte della politica industriale

description: Il lavoro analizza nella prima parte il Piano Nazionale Impresa 4.0, presentato nel settembre 2016 dal Ministro dello Sviluppo economico, evidenziandone le linee direttrici, le finalità e le principali misure che hanno avuto attuazione nelle tre successive leggi di bilancio 2017-2019. Successivamente si forniscono alcune stime sull’impatto del Piano sotto il profilo macroeconomico e in relazione ai giudizi espressi da un campione di imprese sulla base di un’indagine qualitativa svolta dall’ISTAT. Infine, si presentano i principali risultati di un’indagine realizzata dal MET per conto del MiSE, tra il mese di ottobre 2017 e il mese di febbraio del 2018, su un campione di circa 23.700 imprese rappresentativo dell’industria in senso stretto e dei servizi alla produzione, sul tema Impresa 4.0. L’indagine consente un confronto tra le caratteristiche delle imprese 4.0 (utilizzatrici di almeno una tecnologia 4.0 nel triennio 2015-2017), di quelle che hanno in programma di adottare nei prossimi anni almeno una tecnologia 4.0 e di quelle tradizionali (non coinvolte nel processo di digitalizzazione) evidenziando, in particolar modo, il dinamismo virtuoso e le migliori performance delle imprese 4.0. La cosiddetta quarta rivoluzione industriale sta avendo e sempre più avrà un impatto senza precedenti per le imprese italiane, modificandone radicalmente il consolidato paradigma competitivo che negli scorsi decenni ha visto l’Italia primeggiare tra i Paesi avanzati in termini di flessibilità e contenimento del costo dei fattori produttivi. Per competere a livello internazionale e presidiare le catene del valore globale, le nostre imprese sono chiamate a un salto tecnologico a livello sistemico, indipendentemente dal settore economico e dalla dimensione. Come in tutti i grandi processi di innovazione, si aprono dunque opportunità ma anche numerosi rischi, sia sotto il profilo della competitività che soprattutto in termini di ricadute sul mercato del lavoro, con un processo che se non adeguatamente governato può portare al paventato effetto di sostituzione manodopera-robot e che, in ogni caso, richiederà profondi mutamenti nelle competenze dei lavoratori. La parte conclusiva del lavoro, proprio a partire da queste riflessioni, si interroga sulle modifiche che è necessario apportare alle politiche industriali a sostegno dell’innovazione, tenendo presente che le misure generali e automatiche del Piano Nazionale Impresa 4.0 dovrebbero essere destinate prioritariamente alle imprese di micro e piccole dimensioni, finora meno coinvolte. Non meno importante, peraltro, sembrerebbe la necessità di consolidare il percorso di accrescimento delle competenze digitali, sviluppando anche una maggiore interazione tra il mondo scolastico e della ricerca con il mondo produttivo al fine di facilitare il trasferimento tecnologico.

description: We present a new possibility for achieving doublet-triplet splitting naturally in supersymmetric SO(10) grand unified theories. It is based on a missing partner mechanism which is realized with the 126 + 126-bar Higgs superfields. These Higgs fields, which are also needed for generating Majorana right-handed neutrino masses, contain a pair of color triplets in excess of weak doublets. This feature enables us to remove the color triplets from the low energy spectrum without fine-tuning. We give all the needed ingredients for a successful implementation of the missing partner mechanism in SO(10) and present explicit models wherein the Higgs doublet mass is protected against possible non-renormalizable corrections to all orders. We also show how realistic fermion masses can be generated in this context.

description: Let $F_2$ be the binary field and $Z_{2^r}$ the residue class ring of integers modulo $2^r$, where $r$ is a positive integer. For the finite $16$-element commutative local Frobenius non-chain ring $Z_4+uZ_4$, where $u$ is nilpotent of index $2$, two weight functions are considered, namely the Lee weight and the homogeneous weight. With the appropriate application of these weights, isometric maps from $Z_4+uZ_4$ to the binary spaces $F_2^4$ and $F_2^8$, respectively, are established via the composition of other weight-based isometries. The classical Hamming weight is used on the binary space. The resulting isometries are then applied to linear block codes over $Z_4+uZ_4$ whose images are binary codes of predicted length, which may or may not be linear. Certain lower and upper bounds on the minimum distances of the binary images are also derived in terms of the parameters of the $Z_4+uZ_4$ codes. Several new codes and their images are constructed as illustrative examples. An analogous procedure is performed successfully on the ring $Z_8+uZ_8$, where $u^2=0$, which is a commutative local Frobenius non-chain ring of order $64$. It turns out that the method is possible in general for the class of rings $Z_{2^r}+uZ_{2^r}$, where $u^2=0$, for any positive integer $r$, using the generalized Gray map from $Z_{2^r}$ to $F_2^{2^{r-1}}$.

description: The DustPedia project is capitalising on the legacy of the Herschel Space Observatory, using cutting-edge modelling techniques to study dust in the 875 DustPedia galaxies - representing the vast majority of extended galaxies within 3000 km s$^{-1}$ that were observed by Herschel. This work requires a database of multiwavelength imagery and photometry that greatly exceeds the scope (in terms of wavelength coverage and number of galaxies) of any previous local-Universe survey. We constructed a database containing our own custom Herschel reductions, along with standardised archival observations from GALEX, SDSS, DSS, 2MASS, WISE, Spitzer, and Planck. Using these data, we performed consistent aperture-matched photometry, which we combined with external supplementary photometry from IRAS and Planck. We present our multiwavelength imagery and photometry across 42 UV-microwave bands for the 875 DustPedia galaxies. Our aperture-matched photometry, combined with the external supplementary photometry, represents a total of 21,857 photometric measurements. A typical DustPedia galaxy has multiwavelength photometry spanning 25 bands. We also present the Comprehensive & Adaptable Aperture Photometry Routine (CAAPR), the pipeline we developed to carry out our aperture-matched photometry. CAAPR is designed to produce consistent photometry for the enormous range of galaxy and observation types in our data. In particular, CAAPR is able to determine robust cross-compatible uncertainties, thanks to a novel method for reliably extrapolating the aperture noise for observations that cover a very limited amount of background. Our rich database of imagery and photometry is being made available to the community

description: The coupling between defects in diamond and a superconducting microwave resonator is studied in the nonlinear regime. Both negatively charged nitrogen-vacancy and P1 defects are explored. The measured cavity mode response exhibits strong nonlinearity near a spin resonance. Data is compared with theoretical predictions and a good agreement is obtained in a wide range of externally controlled parameters. The nonlinear effect under study in the current paper is expected to play a role in any cavity-based magnetic resonance imaging technique and to impose a fundamental limit upon its sensitivity.

description: Il lavoro analizza l’andamento del valore di mercato dei derivati delle banche italiane utilizzando i conti finanziari e proponendo un confronto internazionale. Per il periodo che va dal primo trimestre del 2001 al terzo trimestre del 2008 è stata, inoltre, ottenuta una stima del valore di mercato sfruttando la continuità della serie dei valori nozionali presenti nelle segnalazioni di vigilanza. L’analisi dell’andamento dei derivati bancari nei principali paesi mostra come il loro valore sia significativamente diminuito a seguito della crisi finanziaria. Alla fine del 2015 l’ammontare dei derivati all’attivo delle istituzioni finanziarie monetarie in rapporto al totale delle attività finanziarie risultava in Italia pari al 4 per cento, valore nettamente inferiore a quello di Regno Unito, Germania e Francia.

description: Existing studies have revealed a paradoxical phenomenon in public goods games, wherein destructive agents, harming both cooperators and defectors, can unexpectedly bolster cooperation. Building upon this intriguing premise, our paper introduces a novel concept: constructive agents, which confer additional benefits to both cooperators and defectors. We investigate the impact of these agents on cooperation dynamics within the framework of public goods games. Employing replicator dynamics, we find that unlike destructive agents, the mere presence of constructive agents does not significantly alter the defective equilibrium. However, when the benefits from constructive agents are outweighed by the damage inflicted by destructive agents, the addition of constructive agents does not affect the ability of destructive agents to sustain cooperation. In this scenario, cooperators can be maintained through a cyclic dominance between cooperators, defectors, and destructive agents, with constructive agents adding complexity but not fundamentally changing the equilibrium. Conversely, if the benefits from constructive agents surpass the harm caused by destructive agents, the presence of constructive agents nullifies the ability of destructive agents to foster cooperation. Our results highlight the nuanced role of constructive agents in cooperation dynamics, emphasizing the necessity of carefully assessing incentive balances when encouraging cooperation.

description: Several simple mergers between model galaxy clusters containing a mixture of gas and dark matter are examined, testing the coupling of the gas to the underlying collisionless material. The gas is shocked, irreversibly dissipating the energy fed into it by the collisionless component and forms a resolved constant-density core. For the dark matter, however, admixture of phase space vacuum is not very efficient and a constant-density core is not produced. In the final state the central gas has little residual kinetic energy, indicating that streaming motions do not help to support the gas.

description: We study the effect of theoretical and parametric uncertainties on the ability of future Higgs coupling measurements at the International Linear Collider (ILC) to reveal deviations from the Standard Model (SM). To quantify the impact of these uncertainties we plot Delta chi^2 = 25 contours for the deviations between the SM Higgs couplings and the light Higgs couplings in the mh-max benchmark scenario of the Minimal Supersymmetric Standard Model (MSSM). We consider the theoretical uncertainties in the SM Higgs decay partial widths and production cross section and the parametric uncertainties in the bottom and charm masses and the strong coupling alpha_s. We find that the impact of the theoretical and parametric uncertainties is moderate in the first phase of ILC data-taking (500 fb-1 at 350 GeV centre-of-mass energy), reducing the "reach" in the CP-odd MSSM Higgs mass M_A by about 10% to ~500 GeV, while in the second phase (1000 fb-1 at 1000 GeV) these uncertainties are larger than the experimental uncertainties and reduce the reach in M_A by about a factor of two, from ~1200 down to ~600 GeV. The bulk of the effect comes from the parametric uncertainties in m_b and alpha_s, followed by the theoretical uncertainty in Gamma_b.

description: A fundamental question for edge detection in noisy images is how faint can an edge be and still be detected. In this paper we offer a formalism to study this question and subsequently introduce computationally efficient multiscale edge detection algorithms designed to detect faint edges in noisy images. In our formalism we view edge detection as a search in a discrete, though potentially large, set of feasible curves. First, we derive approximate expressions for the detection threshold as a function of curve length and the complexity of the search space. We then present two edge detection algorithms, one for straight edges, and the second for curved ones. Both algorithms efficiently search for edges in a large set of candidates by hierarchically constructing difference filters that match the curves traced by the sought edges. We demonstrate the utility of our algorithms in both simulations and applications involving challenging real images. Finally, based on these principles, we develop an algorithm for fiber detection and enhancement. We exemplify its utility to reveal and enhance nerve axons in light microscopy images.
