Probing the QCD vacuum with an abelian chromomagnetic field: A study within an effective model
Leonardo Campanelli, Marco Ruggieri
We study the response of the QCD vacuum to an external abelian chromomagnetic field in the framework of a non local Nambu-Jona Lasinio model with the Polyakov loop. We use the Latt…
Neutral quark matter in a Nambu-Jona Lasinio model with vector interaction
H. Abuki, R. Gatto, M. Ruggieri
We investigate the three flavor Nambu-Jona Lasinio model of neutral quark matter at zero temperature and finite density, keeping into account the scalar, the pseudoscalar and the K…
On the neutrality issue in the Polyakov-loop NJL model
H. Abuki, M. Ciminale, R. Gatto +1
We elucidate how the color neutrality is harmed in the Polyakov Nambu-Jona Lasinio (PNJL) model at finite density within the adopted mean field approximation. Also we point out how…
Phase diagram and pion modes of the neutral Nambu-Jona Lasinio model with the Polyakov loop
M. Ruggieri
I discuss recent results obtained by our group within the Nambu-Jona Lasinio model with the Polyakov loop. I focus on the two flavor version of the model, discussing the phase diag…
A diagrammatic derivation of the meson effective masses in the neutral color-flavor-locked phase of Quantum Chromodynamics
Marco Ruggieri
We offer a diagrammatic derivation of the effective masses of the axial flavor excitations in the electrical and color neutral CFL phase of QCD. In particular we concentrate on the…
Neutrino emission from compact stars and inhomogeneous color superconductivity
R. Anglani, M. Mannarelli, G. Nardulli +1
We discuss specific heat and neutrino emissivity due to direct Urca processes for quark matter in the color superconductive Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) phase of Quantum…
