We investigate the properties of scalar and pseudo-scalar mesons at finite temperature and quark chemical potential in the framework of the Nambu–Jona-Lasinio (NJL) model coupled to the Polyakov loop… (More)

We consider ratios of elastic ν(ν̄)–proton cross sections measured by the Brookhaven BNL–734 experiment and use them to obtain the neutral current (NC) over charged current (CC) neutrino–antineutrino… (More)

Quark Gluon Plasma transport coefficients for heavy quarks and QQ pairs are computed through an extension of the results obtained for a hot QED plasma by describing the heavy-quark propagation in the… (More)

The original B. Pontecorvo idea of neutrino oscillations is discussed. Neutrino mixing and basics of neutrino oscillations in vacuum and in matter are considered. Recent evidences in favour of… (More)

The temporal pseudoscalar meson correlation function in a QCD plasma is investigated in a range of temperatures exceeding T c and yet of experimental interest. Only the flavour-singlet channel is… (More)

The finite momentum meson spectral function (MSF) in the pseudoscalar channel is evaluated, adopting for the fermionic propagators HTL expressions. The different contributions to the meson spectral… (More)

Following the basic prescriptions of the relativistic Tsallis’ non-extensive thermostatistics, we investigate from a phenomenological point of view the relevance of non-extensive statistical effects… (More)

We present a model for quark matter with a density dependent quark– quark (confining) potential, which allows to describe a deconfinement phase transition as the system evolves from a low density… (More)

The meson screening mass in the pseudoscalar channel is calculated from the momentum dependent meson spectral function, using HTL fermionic propagators. A careful subtraction procedure is required to… (More)
