Mesons, baryons and the confinement/deconfinement transition

V. Tomas Mari Surkau, Urko Reinosa

We identify an observable that could operate as a probe of the quark versus hadron content of a bath of quarks and gluons at finite temperature and chemical potential. To this purp…

Deconfinement transition within the Curci-Ferrari model -- Renormalization scale and scheme dependences

V. Tomas Mari Surkau, Urko Reinosa

We analyze the confinement/deconfinement transition of pure Yang-Mills theories within the framework of the center-symmetric Landau gauge supplemented by a Curci-Ferrari mass term…

Interplay between the chiral and deconfinement transitions from a Curci-Ferrari-based Polyakov loop potential

V. Tomas Mari Surkau, Urko Reinosa

We couple the two-flavor Nambu--Jona-Lasinio model to a gluonic background corresponding to the gauge-field expectation value in the center-symmetric Landau gauge. Low-energy featu…

SU() confinement and color -ality

V. Tomas Mari Surkau, Urko Reinosa

In a recent work, we have argued that the net quark number gained by a bath of quarks and gluons upon bringing an external static quark probe, while being equal to in the high…

Scenario for quark confinement from infrared safe Yang-Mills dynamics

Marcela Peláez, Urko Reinosa, Julien Serreau +2

We revisit the non-Abelian dipole problem in the context of a simple semiclassical approach that incorporates some essential features of the infrared sector of Yang-Mills theories…

Using net quark number gain to probe the phases of QCD

V. Tomas Mari Surkau, Urko Reinosa

We discuss an observable that probes the content of a QCD medium at finite temperature and chemical potential, the net quark number gain. It is the response of the thermal bath to…
