description: By means of first-principles calculations, various properties of SrRuO3 are investigated, focusing on its lattice dynamical properties. Despite having a Goldschmidt tolerance factor very close to 1, the phonon dispersion curves of the high-temperature cubic phase of SrRuO3 show strong antiferrodistortive instabilities. The energetics of metastable phases with different tilt patterns are discussed, concluding that the coupling of oxygen-rotation modes with anti-polar Sr motion plays a key role in stabilizing the Pnma phase with respect to alternative rotation patterns. This not only explains the ground state of SrRuO3 but also contributes to rationalize why most ABO3 perovskites exhibit an orthorhombic ground state. The zone-center phonon modes of the Pnma phase have been computed, from which we propose partial reassignment of available experimental data. The full dispersion curves have also been obtained, constituting benchmark results for the interpretation of future measurements and providing access to thermodynamical properties.

THREE-DIMENSIONAL SCAFFOLDS FOR IN VITRO CULTURE OF FELINE OOCYTES.

description: The cumulus-denuded oocytes (CDOs) are not commonly involved in the assisted reproductive techniques (ARTs), as the absence of their surrounding cumulus cells negatively affects their maturational and developmental competence in vitro. In some cases these gametes could represent an interesting option for widening the germinal pool of high value individuals with very precious genetic material and could be the only genetic source when the selected cumulus-oocyte complexes (COCs, grade I) are cryopreserved. Therefore, enriched culture conditions to improve the CDOs in vitro full competence should be adopted. The innovative three-dimensional (3D) scaffolds, derived from the bioengineering and nanotechnology research, ensure the optimal culture conditions to maintain the cells physiological conformation and behavior as in the in vivo environment. In this thesis, the association of 3D barium alginate microcapsules with competent COCs was used to improve the in vitro performances of domestic cat CDOs. The results showed that the 3D BA microcapsules are suitable systems for the in vitro culture of feline oocytes, as their viability and in vitro maturation rates and embryonic development were similar to those obtain in the traditional 2D system. The enriched co-culture condition did not improve the in vitro competence of CDOs, as their full maturational (TI-MII) rates and late embryo stages (morulae and blastocysts) were similar to those of the CDOs cultured separately or to those of the COCs control. However, the presence of CDOs in the co-culture with COCs improved significantly the in vitro developmental rates of the high competence oocytes, presumably for the paracrine action of some specific oocyte-secreted factors (OSFs). A better knowledge of the expression profiles of potential oocyte quality markers, as the OSFs, and how they could differ from COCs and CDOs in the 3D and 2D systems could help the design of the optimal enriched culture conditions for the domestic cat low competence oocytes.

LA CONFISCA DI PREVENZIONE E L'AMMINISTRAZIONE GIUDIZIARIA DI COMPLESSI AZIENDALI
Creators: name: TIANI, ELISABETTA

description: This research aims to examine the prevention measures set against criminal and Mafia organizations and their economic expressions in the Italian system. When Mafia acts like an economic operator or business it is necessary to neutralize its power and the consequent negative effects on the legal society and market. In recent years, the Legislator is realizing that the best way to reach prevention is to attack the illegal properties of Mafia and remove the basis for their development. It is possible to use the same negative prevention measures (preventive seizure, confiscation and legal administration ? articles 20, 24 and 34 D.lgs. nr. 159/2011) like instruments to reach positive prevention through a rehabilitation procedure for criminal companies and their re-integration to the legal marketplace. That action could create huge benefits for the people in terms of legality perception, welfare, employment, legal and free competition, etc. and promote an economic upturn of the legal business system. Despite this, our positive prevention model does not currently work whenever prevention measures are directed to the assets of companies. Confiscated companies very often collapse and default. Therefore our research investigates about the causes of this failure and, at the same time, looks for the factors that led to success in rare cases of restored companies. The job also analyses the latest works and studies on reform carried out by specialized commissions (led by Garofoli, Fiandaca, Bindi and Gratteri) and under ongoing discussion in Parliament with bills nr. 2134/2015, 1687/2014 and 1138/2013: they all seem to dedicate greater importance to the positive prevention policies. At the end, the results of the research allow the Author to propose some considerations in a future perspective about the renovation of the system of prevention against Mafia companies. The real goal of any effective prevention should be to develop the clout of recovered companies to improve the welfare of society and market. In order to do that, State should attack Mafia companies as dynamic and dangerous subject and not consider them as a collection of goods: the danger is connected to how they are managed by criminal people. Further to that, we might also conceive the prevention system to directly attack the companies as autonomous from their Mafia-connected owners.

description: We consider a class of continuous time Markov chains on a compact metric space that admit an invariant measure strictly positive on open sets together with absorbing states. We prove the joint large deviation principle for the empirical measure and flow. Due to the lack of uniform ergodicity, the zero level set of the rate function is not a singleton. As corollaries, we obtain the Donsker-Varadhan rate function for the empirical measure and a variational expression of the rate function for the empirical flow.
Beamforming approaches toward detecting the 21-cm global signal from Cosmic Dawn with radio array telescopes

description: The formation of the first stars and galaxies during 'Cosmic Dawn' is thought to have imparted a faint signal onto the 21-cm spin temperature from atomic Hydrogen gas in the early Universe. Observationally, an absorption feature should be measurable as a frequency-dependence in the sky-averaged (i.e. global) temperature at meter wavelengths. This signal should be separable from the smooth -- but orders of magnitude brighter -- foregrounds by jointly fitting a log-polynomial and absorption trough to radiometer spectra. A majority of approaches to measure the global 21-cm signal use radiometer systems on dipole-like antennas. Here, we argue that beamforming-based methods may allow radio arrays to measure the global 21-cm signal. We simulate an end-to-end drift-scan observation of the radio sky at 50--100 MHz using a zenith-phased array, and find that the complex sidelobe structure introduces a significant frequency-dependent systematic. However, the λ/D evolution of the beam width with frequency does not confound detection. We conclude that a beamformed array with a median sidelobe level around 50 dB below the main beam may offer an alternative method to measure the global 21-cm signal. This level is achievable by arrays with O(10^5) antennas.

description: Infinite Leslie matrices, introduced by Demetrius forty years ago are mathematical models of age-structured populations defined by a countable infinite number of age classes. This article is concerned with determining solutions of the discrete dynamical system in finite time. We address this problem by appealing to the concept of kneading matrices and kneading determinants. Our analysis is applicable not only to populations models, but to models of self-reproducing machines and self-reproducing computer programs. The dynamics of theses systems can also be described in terms of infinite Leslie matrices.uation.

description: We propose a novel renormalization scheme for the hadronic operators. The renormalization factor of the operator in this scheme is normalized by the correlation function at tree level in coordinate space. If we focus on the pseudo scalar operator, then its renormalization factor is related to the mass renormalization factor of the fermion through the partially conserved axial-vector current (PCAC) relation. Using the renormalization factor for the pseudo scalar operator in our scheme, we obtain the mass anomalous dimension of the SU(3) gauge theory coupled to N_f=12 massless fundamental fermions, which has an infrared fixed point (IRFP). The mass anomalous dimension at the IRFP is estimated as gamma_m^*= 0.044_{-0.024}^{+0.025} (stat.)_{-0.032}^{+0.057} (syst.).

description: The increased availability of time series genetic variation data from experimental evolution studies and ancient DNA samples has created new opportunities to identify genomic regions under selective pressure and to estimate their associated fitness parameters. However, it is a challenging problem to compute the likelihood of nonneutral models for the population allele frequency dynamics, given the observed temporal DNA data. Here, we develop a novel spectral algorithm to analytically and efficiently integrate over all possible frequency trajectories between consecutive time points. This advance circumvents the limitations of existing methods which require fine-tuning the discretization of the population allele frequency space when numerically approximating requisite integrals. Furthermore, our method is flexible enough to handle general diploid models of selection where the heterozygote and homozygote fitness parameters can take any values, while previous methods focused on only a few restricted models of selection. We demonstrate the utility of our method on simulated data and also apply it to analyze ancient DNA data from genetic loci associated with coat coloration in horses. In contrast to previous studies, our exploration of the full fitness parameter space reveals that a heterozygote advantage form of balancing selection may have been acting on these loci.

description: The Mermin-Wagner theorem states that long-range magnetic order does not exist in one- or two-dimensional (2D) isotropic magnets with short-ranged interactions. The theorem has been a milestone in magnetism and has been driving the research of recently discovered 2D van der Waals (vdW) magnetic materials from fundamentals up to potential applications. In such systems, the existence of magnetic ordering is typically attributed to the presence of a significant magnetic anisotropy, which is known to introduce a spin-wave gap and circumvent the core assumption of the theorem. Here we show that in finite-size 2D vdW magnets typically found in lab setups (e.g., within millimetres), short-range interactions can be large enough to allow the stabilisation of magnetic order at finite temperatures without any magnetic anisotropy for practical implementations. We demonstrate that magnetic ordering can be created in flakes of 2D materials independent of the lattice symmetry due to the intrinsic nature of the spin exchange interactions and finite-size effects in two-dimensions. Surprisingly we find that the crossover temperature, where the intrinsic magnetisation changes from superparamagnetic to a completely disordered paramagnetic regime, is weakly dependent on the system length, requiring giant sizes (e.g., of the order of the observable universe ~10$^{26}$ m) in order to observe the vanishing of the magnetic order at cryogenic temperatures as expected from the Mermin-Wagner theorem. Our findings indicate exchange interactions as the main driving force behind the stabilisation of short-range order in 2D magnetism and broaden the horizons of possibilities for exploration of compounds with low anisotropy at an atomically thin level.

description: We develop a fully continuous model for colloidal suspensions with hydrodynamic interactions. The Navier Stokes Phase Field Crystal (NS-PFC) model combines ideas of dynamic density functional theory with particulate flow approaches and is derived in detail and related to other dynamic density functional theory approaches with hydrodynamic interactions. The derived system is numerically solved using adaptive finite elements and used to analyse colloidal crystallization in flowing environments demonstrating a strong coupling in both directions between the crystal shape and the flow field. We further validate the model against other computational approaches for particulate flow systems for various colloidal sedimentation problems.

description: We propose to study the lattice-symmetry protection of Majorana zero bound modes in topological crystalline superconductors (SCs). With an induced $s$-wave superconductivity in the $(001)$-surface of the topological crystalline insulator Pb$_{1-x}$Sn$_x$Te, which has a C$_4$ rotational symmetry, we show a new class of 2D topological SC with four Majorana modes obtained in each vortex core, while only two of them are protected by the cyclic symmetry. Furthermore, applying an in-plane external field can break the four-fold symmetry and lifts the Majorana modes to finite energy states in general. Surprisingly, we show that even the C$_4$ symmetry is broken, two Majorana modes are restored exactly one time whenever the in-plane field varies $π/2$, i.e. $1/4$-cycle in the direction. This novel phenomenon has a profound connection to the four-fold cyclic symmetry of the original crystalline SC and uniquely demonstrates the lattice-symmetry protection of the Majorana modes. We further generalize these results to the system with generic C$_{2N}$ symmetry, and show that the symmetry class of the topological crystalline SC can be demonstrated by the $2N$ times of restoration of two Majorana modes when the external symmetry-breaking field varies one cycle in direction.

description: Let $K$ be an algebraically closed field of null characteristic and $p(z)$ a Hilbert polynomial. We look for the minimal Castelnuovo-Mumford regularity $m_{p(z)}$ of closed subschemes of projective spaces over $K$ with Hilbert polynomial $p(z)$. Experimental evidences led us to consider the idea that $m_{p(z)}$ could be achieved by schemes having a suitable minimal Hilbert function. We give a constructive proof of this fact. Moreover, we are able to compute the minimal Castelnuovo-Mumford regularity $m_p(z)^{\varrho}$ of schemes with Hilbert polynomial $p(z)$ and given regularity $\varrho$ of the Hilbert function, and also the minimal Castelnuovo-Mumford regularity $m_u$ of schemes with Hilbert function $u$. These results find applications in the study of Hilbert schemes. They are obtained by means of minimal Hilbert functions and of two new constructive methods which are based on the notion of growth-height-lexicographic Borel set and called ideal graft and extended lifting.

description: Given a principal fibre bundle with structure group $S$, and a fibre transitive Lie group $G$ of automorphisms thereon, Wang's theorem identifies the invariant connections with certain linear maps $ψ\colon \mathfrak{g}\rightarrow \mathfrak{s}$. In the present paper, we prove an extension of this theorem which applies to the general situation where $G$ acts non-transitively on the base manifold. We consider several special cases of the general theorem, including the result of Harnad, Shnider and Vinet which applies to the situation where $G$ admits only one orbit type. Along the way, we give applications to loop quantum gravity.

description: Given sufficient training data on the source domain, cross-domain few-shot learning (CD-FSL) aims at recognizing new classes with a small number of labeled examples on the target domain. The key to addressing CD-FSL is to narrow the domain gap and transferring knowledge of a network trained on the source domain to the target domain. To help knowledge transfer, this paper introduces an intermediate domain generated by mixing images in the source and the target domain. Specifically, to generate the optimal intermediate domain for different target data, we propose a novel target guided dynamic mixup (TGDM) framework that leverages the target data to guide the generation of mixed images via dynamic mixup. The proposed TGDM framework contains a Mixup-3T network for learning classifiers and a dynamic ratio generation network (DRGN) for learning the optimal mix ratio. To better transfer the knowledge, the proposed Mixup-3T network contains three branches with shared parameters for classifying classes in the source domain, target domain, and intermediate domain. To generate the optimal intermediate domain, the DRGN learns to generate an optimal mix ratio according to the performance on auxiliary target data. Then, the whole TGDM framework is trained via bi-level meta-learning so that TGDM can rectify itself to achieve optimal performance on target data. Extensive experimental results on several benchmark datasets verify the effectiveness of our method.

Localized standard versus reduced formula and genus one local Gromov-Witten invariants

Publisher: name: arXiv

Subjects: subject: Algebraic Geometry (math.AG)
subject: FOS: Mathematics

description: For local Calabi-Yau manifolds which are total spaces of vector bundle over balloon manifolds, we propose a formal definition of reduced Genus one Gromov-Witten invariants, by assigning contributions from the refined decorated rooted trees. We show that this definition satisfies a localized version of the standard versus reduced formula, whose global version in the compact cases is due to A. Zinger. As an application we prove the conjecture in a previous article on the genus one Gromov-Witten invariants of local Calabi-Yau manifolds which are total spaces of concave splitting vector bundles over projective spaces. In particular, we prove the mirror formulae for genus one Gromov-Witten invariants of $K_{\mathbb{P}^{2}}$ and $K_{\mathbb{P}^{3}}$, conjectured by Klemm, Zaslow and Pandharipande. In the appendix we derive the modularity of genus one Gromov-Witten invariants for the local $\mathbb{P}^{2}$ as a consequence of the results on Ramanujan's cubic transformation. Inspired by the localized standard versus reduced formula, we show that the ordinary genus one Gromov-Witten invariants of Calabi-Yau hypersurfaces in projective spaces can be computed by virtual localization after the contribution of a genus one vertex is replaced by a modified one.

description: Motivated by recent cold atom experiments in optical lattices, we consider a lattice version of the Landau-Zener problem. Every single site is described by a Landau-Zener problem, but due to particle tunnelling between neighboring lattice sites this onsite single particle Landau-Zener dynamics couples to the particle motion within the lattice. The lattice, apart from having a dephasing effect on single site Landau-Zener transitions, also implies, in the presence of a confining trap, an inter-site particle flow induced by the Landau-Zener sweeping. This gives rise to an interplay between intra- and inter-site dynamics. The adiabaticity constrain is therefor not simply given by the standard one; the Hamiltonian rate of change relative to the gap of the onsite problem. In experimentally realistic situations, the full system evolution is well described by Franck-Condon physics, e.g. non-adiabatic excitations are predominantly external ones characterized by large phononic vibrations in the atomic cloud, while internal excitations are very weak as close to perfect onsite transitions take place.

description: Following previous work, we distinguish between genuine $N$-partite entanglement and full $N$-partite inseparability. Accordingly, we derive criteria to detect genuine multipartite entanglement using continuous variable (position and momentum) measurements. Our criteria are similar but different to those based on the van Loock-Furusawa inequalities, which detect full $N$-partite inseparability. We explain how the criteria can be used to detect the genuine $N$-partite entanglement of continuous variable states generated from squeezed and vacuum state inputs, including the continuous variable Greenberger-Horne-Zeilinger state, with explicit predictions for up to $N=9$$ $. This makes our work accessible to experiment. For $N=3$, we also present criteria for tripartite Einstein-Podolsky-Rosen (EPR) steering. These criteria provide a means to demonstrate a genuine three-party EPR paradox, in which any single party is steerable by the remaining two parties.

description: We study the kinematics of emission lines that arise from many physical processes in NGC 6153 based upon deep, spatially-resolved, high resolution spectra acquired with the UVES spectrograph at the ESO VLT. Our most basic finding is that the plasma in NGC 6153 is complex, especially its temperature structure. The kinematics of most emission lines defines a classic expansion law, with the outer part expanding fastest (normal nebular plasma). However, the permitted lines of \ion{O}{1}, \ion{C}{2}, \ion{N}{2}, \ion{O}{2}, and \ion{Ne}{2} present a constant expansion velocity that defines a second kinematic component (additional plasma component). The physical conditions imply two plasma components, with the additional plasma component having lower temperature and higher density. The [\ion{O}{2}] density and the [\ion{N}{2}] temperature are anomalous, but may be understood considering the contribution of recombination to these forbidden lines. The two plasma components have very different temperatures. The normal nebular plasma appears to be have temperature fluctuations in part of its volume (main shell), but only small fluctuations elsewhere. The additional plasma component contains about half of the mass of the N$^{2+}$ and O$^{2+}$ ions, but only $3-5$\% of the mass of H$^+$ ions, so the two plasma components have very different chemical abundances. We estimate abundances of $12+\log(\mathrm O^{2+}/\mathrm H^+)\sim 9.2$\,dex and $\mathrm{He}/\mathrm H\sim 0.13$. Although they are all complications, multiple plasma components, temperature fluctuations, and the contributions of multiple physical processes to a given emission line are all part of the reality in NGC 6153, and should generally be taken into account.

description: Suppose that $F(x)\in\mathbb{Z}[[x]]$ is a Mahler function and that $1/b$ is in the radius of convergence of $F(x)$. In this paper, we consider the approximation of $F(1/b)$ by algebraic numbers. In particular, we prove that $F(1/b)$ cannot be a Liouville number. If $F(x)$ is also regular, we show that $F(1/b)$ is either rational or transcendental, and in the latter case that $F(1/b)$ is an $S$-number or a $T$-number.

Subjects: subject: Combinatorics (math.CO)

description: We present a determinantal formula for the steady state probability of each state of the TASEP (Totally Asymmetric Simple Exclusion Process) with open boundaries, a 1D particle model that has been studied extensively and displays rich combinatorial structure. These steady state probabilities are computed by the enumeration of Catalan tableaux, which are certain Young diagrams filled with $α$'s and $β$'s that satisfy some conditions on the rows and columns. We construct a bijection from the Catalan tableaux to weighted lattice paths on a Young diagram, and from this we enumerate the paths with a determinantal formula, building upon a formula of Narayana that counts unweighted lattice paths on a Young diagram. Finally, we provide a formula for the enumeration of Catalan tableaux that satisfy a given condition on the rows, which corresponds to the steady state probability that in the TASEP on a lattice with $n$ sites, precisely $k$ of the sites are occupied by particles. This formula is an $α /\ β$ generalization of the Narayana numbers.

description: Η κατασκευή μιας οδοντικής αποκατάστασης βασίζεται τόσο σε κλινικά όσο και εργαστηριακά στάδια. Για την επιτυχία όμως μιας τέτοιας αποκατάστασης, η οποία θα αναπληρώσει και θα αποκαταστήσει τον εκλιπόντα ιστό-δόντι, εναρμονισμένη πλήρως με το στοματογναθικό περιβάλλον απαιτείται η καταγραφή της σχέσης των δυο γνάθων αλλά και η καταγραφή των δοντιών του ενός οδοντικού τόξου με τους ανταγωνιστές του. Οι καταγραφές αυτές γίνονται από τον κλινικό ιατρό με ψηφιακά η αναλογικά μέσα και έπειτα αποστέλλονται στο οδοντικό εργαστήριο. Είτε τα στοιχεία έχουν προέλθει από ψηφιακά είτε από αναλογικά μέσα πρέπει να γίνει η ανάρτηση αυτών σε αρθρωτήρα. Ο αρθρωτήρας είναι ένα όργανο το οποίο είναι ικανό να αναπαράγει την σχέση των γνάθων και τις κινήσεις της κάτω γνάθου. Κάτω από αυτό το πρίσμα ο οδοντικός τεχνολόγος έχει στην κατοχή του μια προσομοίωση της λειτουργίας του στοματογναθικού συστήματος του εκάστοτε ασθενή. Όπως και η αποτύπωση έτσι και οι αρθρωτήρες διατίθενται σε αναλογική και ψηφιακή μορφή. Οι μηχανικοί αρθρωτήρες υστερούν στην ακριβή αναπαράσταση των κινήσεων της κάτω γνάθου καθώς δεν είναι δυνατόν να παρέχουν χρονοεξαρτώμενες μυϊκές κινήσεις κατά την διάρκεια του μασητικού κύκλου. Παράλληλα, δημιουργούνται και πολλά λάθη λόγω της μακράς διαδικασίας τα οποία ελαττώνουν την ακρίβεια της τελικής αποκατάστασης. Τα όρια των μηχανικών αρθρωτήρων δημιούργησαν την ανάγκη για εύρεση νέων μεθόδων αναπαράστασης του στοματογναθικού συστήματος αλλά και καταγραφής. Αυτή η ανάγκη οδήγησε στην ανακάλυψη του εικονικού αρθρωτήρα, ο οποίος έχει την δυνατότητα λεπτομερέστερης καταγραφής των γνάθων και αναπαραγωγής των κινήσεων. Την αποτελεσματικότητα των εικονικών αρθρωτήρων έρχονται να συμπληρώσουν νέα τεχνολογικά μέσα καταγραφής τόσο ενδοστοματικά όσο και εξωστοματικά αλλά και τα σύγχρονα συστήματα CAD-CAM. Ωστόσο ακόμα και τα πιο εξελιγμένα ψηφιακά μέσα αποτύπωσης και αναπαραγωγής του στοματογναθικού συστήματος χρήζουν βελτίωσης.

Constraining the Little Higgs model of Schmaltz, Stolarski, and Thaler with recent results from the LHC

description: In this paper, we use the latest Higgs measurements from ATLAS and CMS to constrain the parameter space of the model of Schmaltz, Stolarski and Thaler, a Little Higgs model with two Higgs doublets, which we will refer to as the BLH model. We account for all production and decay modes explored at ATLAS and CMS in two scenarios: a general case, which assumes the $h_0$ state is light ($m_{h_0} \approx 125$ GeV) and the masses of the other neutral scalars ($H_0$ and $A_0$) are allowed to vary, and a case with a near-degeneracy between the masses of the $h_0$ and $A_0$ and, for some choices of parameters, the $H_0$ states. The near-degeneracy scenario can result in an enhanced diphoton rate, as measured by ATLAS, but is largely ruled out by a combination of the $h_0 \rightarrow τ^+τ^-$ and the heavy $H_0 \rightarrow W^+W^-$ measurements. In the general case, we find large regions of parameter space that are in better agreement with either the ATLAS or CMS results than is the SM. However, a significantly enhanced diphoton rate is only possible through large contributions to the $h_0 γγ$ effective coupling from charged Higgs bosons in a region of parameter space that borders on violation of perturbativity in the scalar sector.

Cold gas mass measurements for the era of large optical spectroscopic surveys

description: Gas plays an important role in many processes in galaxy formation and evolution, but quantifying the importance of gas has been hindered by the challenge to measure gas masses for large samples of galaxies. Datasets of direct atomic and molecular gas measurements are sufficient to establish simple scaling relations, but often not large enough to quantify three-parameter relations, or second order dependencies. As an alternative approach, we derive here indirect cold gas measurements from optical emission lines using photoionization models for galaxies in the SDSS main galaxy sample and the PHANGS-MUSE survey. We calibrate the gas surface density measurements using xCOLD GASS and PHANGS-ALMA molecular gas measurements to ensure our measurements are reliable. We demonstrate the importance of taking into account the scale-dependence of the relation between optical depth ($τ_V$) and gas surface density ($Σ_{gas}$) and provide a general prescription to estimate $Σ_{gas}$ from $τ_V$, metallicity and the dust-to-metal ratio, at any arbitrary physical resolution. To demonstrate that the indirect cold gas masses are accurate enough to quantify the role of gas in galaxy evolution, we study the mass-metallicity relation (MZR) of SDSS galaxies and show that as a third parameter, gas mass is better than SFR at reducing the scatter of the relation, as predicted by models and simulations.

Probing Lorentz Invariance Violation with Neutrino Factories
Creators: name: Rossi-Torres, F.
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this article we show the modification in the number of neutrino events ($ν_μ+\barν_μ$) caused by Lorentz Invariant Violation (LIV), $σ=5\times 10^{-24}$ and $10^{-23}$, in neutrino oscillation for a neutrino factory at a distance of 7500 km. The momentum of the muons can vary from 10-50 GeV and we consider $2\times 10^{20}$ decays per year. The modifications in the number of events caused by this $σ$ LIV parameter could be a strong signal of new physics in a future neutrino factory.
