Magnetized QCD phase diagram: critical end points for the strange quark phase transition driven by external magnetic fields
Pedro Costa, Márcio Ferreira, Constança Providência
In this work we examine possible effects of an external magnetic field in the strongly interacting matter phase diagram. The study is performed using the Polyakov-Nambu-Jona-Lasini…
The effects of explicit chiral symmetry breaking multiquark interactions on the spin 0 and 1 meson nonets: the ruling of the vector mesons
Jorge Morais, Brigitte Hiller, Alexander A. Osipov
We have recently extended the scalar-pseudoscalar sector of a generalized NJL Lagrangian that includes all NLO non derivative interactions in Nc counting (including explicit symmet…
Relativistic particle in a box: Klein-Gordon vs Dirac Equations
Pedro Alberto, Saurya Das, Elias C. Vagenas
The problem of a particle in a box is probably the simplest problem in quantum mechanics which allows for significant insight into the nature of quantum systems and thus is a corne…
Finite temperature gluon propagator in Landau gauge: non-zero Matsubara frequencies and spectral densities
Paulo J. Silva, Orlando Oliveira, David Dudal +1
We report on the lattice computation of the Landau gauge gluon propagator at finite temperature, including the non-zero Matsubara frequencies. Moreover, the corresponding Källén-Le…
Hyperons in hot dense matter: what do the constraints tell us for equation of state?
M. Fortin, M. Oertel, C. Providência
For core-collapse and neutron star merger simulations it is important to have at hand adequate equations of state, describing the underlying dense and hot matter as realistically a…
Thermodynamics of general flat space and boson star quasi-local systems
Yan Peng, Jianjun Fang, Shuangxi Yi +1
We study thermodynamics of flat space/boson star systems enclosed in a scalar reflecting box with Stckelberg mechanism. We also disclose effects of model parameters on tr…
On the Bose symmetry and the left- and right-chiral anomalies
J. S. Porto, A. R. Vieira, A. L. Cherchiglia +2
It is generally assumed that in order to preserve Bose symmetry in the left- (or right-chiral) current it is necessary to equally distribute the chiral anomaly between the vectoria…
Warm unstable asymmetric nuclear matter: critical properties and the density dependence of the symmetry energy
N. Alam, H. Pais, C. Providência +1
The spinodal instabilities in hot asymmetric nuclear matter and some important critical parameters derived thereof are studied using six different families of relativistic mean-fie…
A general framework to diagonalize vector--scalar and axial-vector--pseudoscalar transitions in the effective meson Lagrangian
Jorge Morais, Brigitte Hiller, Alexander A. Osipov
A new mathematical framework for the diagonalization of the nondiagonal vector--scalar and axial-vector--pseudoscalar mixing in the effective meson Lagrangian is described. This pr…
To , or not to : Recent developments and comparisons of regularization schemes
C. Gnendiger, A. Signer, D. Stöckinger +16
We give an introduction to several regularization schemes that deal with ultraviolet and infrared singularities appearing in higher-order computations in quantum field theories. Co…
Effect of strong magnetic fields on the crust-core transition and inner crust of neutron stars
Jianjun Fang, Helena Pais, Sagar Pratapsi +3
The Vlasov equation is used to determine the dispersion relation for the eigenmodes of magnetized nuclear and neutral stellar matter, taking into account the anomalous magnetic mom…
Reply to "Comment on 'Lattice Gluon and Ghost Propagators, and the Strong Coupling in Pure SU(3) Yang-Mills Theory: Finite Lattice Spacing and Volume Effects' "
Anthony G. Duarte, Orlando Oliveira, Paulo J. Silva
The quenched gluon and ghost propagator data published in [1] is reanalysed following the suggestion of [2] to resolve the differences between the infrared data of the simulations.…
Light Clusters and Pasta Phases in Warm and Dense Nuclear Matter
Sidney S. Avancini, Márcio Ferreira, Helena Pais +2
The pasta phases are calculated for warm stellar matter in a framework of relativistic mean-field models, including the possibility of light cluster formation. Results from three d…
Approximate dual representation for Yang-Mills SU(2) gauge theory
R. Leme, O. Oliveira, G. Krein
An approximate dual representation for non-Abelian lattice gauge theories in terms of a new set of dynamical variables, the plaquette occupation numbers (PONs) that are natural num…
Masses of the lowest spin-0 and spin-1 meson nonets: explicit symmetry breaking effects
Jorge Morais, Brigitte Hiller, Alexander A. Osipov
We extend a known multi-quark three-flavor Lagrangian of the Nambu-Jona-Lasinio type, which includes a set of effective interactions proportional to the current quark masses, to in…
