Charmonium and D mesons in hadronic matter
(2010-12-14)
We discuss two aspects of charmonium in medium. First, we present results of a recent study that compares the phenomenology of charmonium spectroscopy using smooth and sudden string breaking potentials. Next, we present ...
Mass dependence of the deconfinement and chiral restoration critical temperatures in nonlocal SU(2) Polyakov-Nambu-Jona-Lasinio models
(American Physical Society, 2013-01)
In the framework of nonlocal SU(2) chiral quark models with Polyakov loop, we analyze the dependence of the deconfinement and chiral restoration critical temperatures on the explicit chiral symmetry breaking driven by the ...
Chiral-symmetry restoration in clustered hadronic matter
(Springer, 2003-11-01)
Chiral-symmetry restoration is usually discussed in the context of quark matter, a system of deconfined quarks. However, many systems like stable nuclei and neutron stars have quarks confined within nucleons. In the present ...

Meson phenomenology and phase transitions in nonlocal chiral quark models
(IOP Publishing, 2015-07)
We study the features of nonlocal chiral quark models that include wave function renormalization. Model parameters are determined from meson phenomenology, considering different nonlocal form factor shapes. In this context ...

Strong magnetic fields in nonlocal chiral quark models
(American Physical Society, 2017-12)
We study the behavior of strongly interacting matter under a uniform intense external magnetic field in the context of nonlocal extensions of the Polyakov-Nambu-Jona-Lasinio model. A detailed description of the formalism ...
Decoupling of quark condensate from the effective nucleon mass at high density (ϱ) and temperature (T)
(1995-11-16)
It is found that the quark condensate 〈qq〉, instead of decreasing at high ρ{variant}, as commonly expected, starts to increase after a certain density (∼ 1.5ρ{variant}0 - in standard relativistic nuclear matter models. ...
