Excluded-volume model for quarkyonic matter II: Three-flavor shell-like distribution of baryons in phase space

Dyana C. Duarte, Saul Hernandez-Ortiz, Kie Sang Jeong

We extend the excluded-volume model of isospin symmetric two-flavor dense quarkyonic matter [Phys. Rev. C 101, 035201 (2020)] including strange particles and address its implicatio…

Fluctuating temperature and baryon chemical potential in heavy-ion collisions and the position of the critical end point in the effective QCD phase diagram

Alejandro Ayala, Saul Hernandez-Ortiz, Luis A. Hernandez +2

We use the linear sigma model with quarks to locate the critical end point in the effective QCD phase diagram accounting for fluctuations in temperature and quark chemical potentia…

Excluded-volume model for quarkyonic Matter: Three-flavor baryon-quark Mixture

Dyana C. Duarte, Saul Hernandez-Ortiz, Kie Sang Jeong

The single-flavor excluded-volume model based on the effective size of baryons reproduces the hard-soft density evolution of the equation of state (EoS) required by the recent stud…

Magnetic field-dependence of the neutral pion mass in the linear sigma model coupled to quarks: The weak field case

Alejandro Ayala, Ricardo L. S. Farias, S. Hernandez-Ortiz +3

We compute the neutral pion mass dependence on a magnetic field in the weak field approximation at one-loop order. The calculation is carried out within the linear sigma model coup…

Thermo-magnetic evolution of the QCD strong coupling

Alejandro Ayala, C. A. Dominguez, Saul Hernandez-Ortiz +4

We study the one-loop gluon polarization tensor at zero and finite temperature in the presence of a magnetic field, to extract the thermo-magnetic evolution of the strong coupling…

Thermal corrections to the gluon magnetic Debye mass

Alejandro Ayala, Jorge David Castaño-Yepes, C. A. Dominguez +5

We compute the gluon polarization tensor in a thermo-magnetic environment in the strong magnetic field limit at zero and high temperature. The magnetic field effects are introduced…
