Chiral symmetry restoration in static-light mesons: chiral restoration theorem, the quark running mass m(k) and first chiral restoration signals in the lattice QCD spectra
P. Bicudo
Chiral symmetry restoration high in the hadron spectra is expected but it remains to be confirmed both in lattice QCD computations and in experiments. Recently, a theorem was deriv…
Binary pulsars as dark-matter probes
Paolo Pani
During the motion of a binary pulsar around the Galactic center, the pulsar and its companion experience a wind of dark-matter particles that can affect the orbital motion through…
Dynamical system analysis for nonminimal torsion-matter coupled gravity
Sante Carloni, Francisco S. N. Lobo, Giovanni Otalora +1
In this work, we perform a detailed dynamical analysis for the cosmological applications of a nonminimal torsion-matter coupled gravity. Two alternative formalisms are proposed, wh…
Topological invariants for phase transition points of one-dimensional topological systems
Linhu Li, Chao Yang, Shu Chen
We study topological properties of phase transition points of two topologically non-trivial classes (D and DIII) in one dimension by assigning a Berry phase defined…
AWAKE, The Advanced Proton Driven Plasma Wakefield Acceleration Experiment at CERN
E. Gschwendtner, E. Adli, L. Amorim +88
The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) aims at studying plasma wakefield generation and electron acceleration driven by proton bunches. It is a…
The sensitivity of R_pA to color recombination effects
Korinna Christina Zapp, Guilherme Milhano, Urs Achim Wiedemann
In hadronization models with color recombination, partons are allowed to regroup into color singlet structures that are different from those determined by the perturbative parton s…
Laser absorption via QED cascades in counter propagating laser pulses
Thomas Grismayer, Marija Vranic, Joana L. Martins +2
A model for laser light absorption in electron-positron plasmas self-consistently created via QED cascades is described. The laser energy is mainly absorbed due to hard photon emis…
Analytic self-force calculations in the post-Newtonian regime: eccentric orbits on a Schwarzschild background
Seth Hopper, Chris Kavanagh, Adrian C. Ottewill
We present a method for solving the first-order field equations in a post-Newtonian (PN) expansion. Our calculations generalize work of Bini and Damour and subsequently Kavanagh et…
Vacuum decay in an interacting multiverse
S. Robles-Pérez, A. Alonso-Serrano, C. Bastos +1
We examine a new multiverse scenario in which the component universes interact. We focus our attention to the process of "true" vacuum nucleation in the false vacuum within one sin…
Bell operator and Gaussian squeezed states in noncommutative quantum mechanics
Catarina Bastos, Alex E. Bernardini, Orfeu Bertolami +2
One examines putative corrections to the Bell operator due to the noncommutativity in the phase-space. Starting from a Gaussian squeezed envelop whose time evolution is driven by c…
Bifurcations analysis of the twist-Fréedericksz transition in a nematic liquid-crystal cell with pre-twist boundary conditions: the asymmetric case
Fernando P. da Costa, Maria Isavel Méndez, João T. Pinto
In the paper [Eur. J. of Appl. Math. \textbf{20}, (2009) 269--287] by da Costa et al. the twist-Fréedericksz transition in a nematic liquid crystal one-dimensional cell of lenght $…
Rôle of the pion electromagnetic form factor in the timelike transition
G. Ramalho, M. T Pena, J. Weil +2
The magnetic dipole form factor () is described here within a new covariant model that combines the valence quark core together with the pion cloud…
Study on Coulomb explosions of ion mixtures
E. Boella, B. Peiretti Paradisi, A. D'Angola +2
The paper presents a theoretical work on the dynamics of Coulomb explosion for spherical nanoplasmas composed by two different ion species. Particular attention has been dedicated…
Persistent Homology and String Vacua
Michele Cirafici
We use methods from topological data analysis to study the topological features of certain distributions of string vacua. Topological data analysis is a multi-scale approach used t…
Sub-jet structure as a discriminating quenching probe
Xiaoming Zhang, Liliana Apolinário, José Guilherme Milhano +1
In this work, we propose a new class of jet substructure observables which, unlike fragmentation functions, are largely insensitive to the poorly known physics of hadronization. We…
Radiating black holes in Einstein-Maxwell-dilaton theory and cosmic censorship violation
Pedro Aniceto, Paolo Pani, Jorge V. Rocha
We construct exact, time-dependent, black hole solutions of Einstein-Maxwell-dilaton theory with arbitrary dilaton coupling, . For this theory arises as the four-dimension…
Sequencing BPS Spectra
Sergei Gukov, Satoshi Nawata, Ingmar Saberi +2
This paper provides both a detailed study of color-dependence of link homologies, as realized in physics as certain spaces of BPS states, and a broad study of the behavior of BPS s…
The generation of magnetic fields by the Biermann battery and the interplay with the Weibel instability
K. M. Schoeffler, N. F. Loureiro, R. A. Fonseca +1
An investigation of magnetic fields generated in an expanding bubble of plasma with misaligned temperature and density gradients (driving the Biermann battery mechanism) is perform…
Leading-order determination of the gluon polarisation from semi-inclusive deep inelastic scattering data
C. Adolph, M. Aghasyan, R. Akhunzyanov +217
Using a novel analysis technique, the gluon polarisation in the nucleon is re-evaluated using the longitudinal double-spin asymmetry measured in the cross section of semi-inclusive…

Eugeny Babichev, Richard Brito, Paolo Pani
We consider generic linear perturbations of a nonbidiagonal class of static black-hole solutions in massive (bi)gravity. We show that the quasinormal spectrum of these solutions co…
