Hard-core Radius of Nucleons within the Induced Surface Tension Approach
K. A. Bugaev, A. I. Ivanytskyi, V. V. Sagun +9
In this work we discuss a novel approach to model the hadronic and nuclear matter equations of state using the induced surface tension concept. Since the obtained equations of stat…
Can dark matter drive electroweak symmetry breaking?
Catarina Cosme, João G. Rosa, Orfeu Bertolami
We consider the possibility of an oscillating scalar field accounting for dark matter and dynamically controlling the spontaneous breaking of the electroweak symmetry through a Hig…
Gauge covariant approach to the electroweak interactions of mesons in the Nambu-Jona-Lasinio model with spin-1 states
A. A. Osipov, B. Hiller, P. M. Zhang
An extended Nambu-Jona-Lasinio (NJL) model with chiral group and spin-0 and spin-1 four quark interactions is used to develop the gauge covariant approach to the…
Hadronic electroweak current and mixing
A. A. Osipov, B. Hiller, P. M. Zhang
It is found that in presence of electroweak interactions the gauge covariant diagonalization of the axial-vector -- pseudoscalar mixing in the effective meson Lagrangian leads to a…
Heavy quarkonia: the beauty and the beasts
George Rupp, Eef van Beveren
New enhancements in the charmonium and bottomonium spectra observed since 2003 are very briefly reviewed. Special attention is paid to (formerly ) owing to…
Exploring the Quark-Gluon Vertex with Slavnov-Taylor Identities and Lattice Simulations
Orlando Oliveira, T. Frederico, W. de Paula +1
The soft gluon limit of the longitudinal part of the quark-gluon vertex is studied by resorting to non-perturbative approaches to Quantum Chromodynamics (QCD). Based on a Slavnov-T…
The Quark-Gluon Vertex and the QCD Infrared Dynamics
O. Oliveira, W. de Paula, T. Frederico +1
The Dyson-Schwinger quark equation is solved for the quark-gluon vertex using the most recent lattice data available in the Landau gauge for the quark, gluon and ghost propagators,…
Net baryon-number fluctuations in magnetized quark matter
Márcio Ferreira, Pedro Costa, Constança Providência
The kurtosis and skewness of net baryon-number fluctuations are studied for the magnetized phase diagram of three-flavor quark matter within the Polyakov extended NambuJona-Lasi…
The presence of a critical end point in the QCD phase diagram from the net-baryon number fluctuations
Márcio Ferreira, Pedro Costa, Constança Providência
The net-baryon number fluctuations for three-flavor quark matter are computed within the Polyakov extended NambuJona-Lasinio model. Two models with vanishing and nonvanishing ve…
Thermodynamical properties of strongly interacting matter in a model with explicit chiral symmetry breaking interactions
J. Moreira, J. Morais, B. Hiller +2
We analyse the effects of the light and strange current quark masses on the phase diagram of QCD at finite temperature and vanishing baryonic chemical potential, computing the spee…
Multiple critical end points in magnetized three flavor quark matter
Márcio Ferreira, Pedro Costa, Constança Providência
The magnetized phase diagram for three-flavor quark matter is studied within the Polyakov extended Nambu--Jona-Lasinio model. The order parameters are analyzed with special emphasi…
Spontaneous magnetization under a pseudovector interaction between quarks in high density quark matter
M. Morimoto, Y. Tsue, J. da Providencia +2
Spontaneous magnetization and magnetic susceptibility originated from the pseudovector-type four-point interaction between quarks are calculated in quark matter with zero temperatu…
