Massive cold hybrid stars in a modified Polyakov-Nambu-Jona-Lasinio model
Sk Md Adil Imam, Pedro Costa, Mariana Dutra +3
We propose a modified Polyakov-loop Nambu--Jona-Lasinio (mPNJL) model in which the Polyakov potential is given by an explicit dependence on the quark chemical potential, allowing i…
A new approach to the 3-momentum regularization of the in-medium one and two fermion line integrals with applications to cross sections in the Nambu--Jona-Lasinio model
Renan Câmara Pereira, João Moreira, Pedro Costa +1
We propose the 3-momentum sphere intersection regularization applied to the one and two fermion line integrals at finite temperature and chemical potential. The quark-antiquark pol…
Building models of quarks and gluons with an arbitrary number of colors using Cartan-Polyakov loops
Renan Câmara Pereira, Pedro Costa
In this work we introduce the concept of Cartan-Polyakov loops, a special subset of Polyakov loops in the fundamental representation of the group, with charges $…
Evaluation of the potential of a gamma-ray observatory to detect astrophysical neutrinos through inclined showers
Jaime Alvarez-Muñiz, Ruben Conceição, Pedro J. Costa +2
We assess the capabilities of a ground-based gamma-ray observatory to detect astrophysical neutrinos with energies in the to range. The identifica…
The strange critical endpoint and isentropic trajectories in an Extended PNJL Model with Eight Quark Interactions
Renan Câmara Pereira, João Moreira, Pedro Costa
In this work, we explore the possible existence of several critical endpoints in the phase diagram of strongly interacting matter using an extended PNJL model with 't Hooft determi…
Functional renormalization group study of the critical region of the quark-meson model with vector interactions
Renan Câmara Pereira, Rainer Stiele, Pedro Costa
The critical region of the two flavour quark-meson model with vector interactions is explored using the Functional Renormalization Group technique, a non-perturbative method that t…
Aspects of isentropic trajectories in chiral effective models
Rainer Stiele, Wanda Maria Alberico, Andrea Beraudo +4
The evolution of the fireball in heavy ion collisions is an isentropic process, meaning that it follows a trajectory of constant entropy per baryon in the phase diagram of the stro…
