Density screening effects in the NJL model: Chiral condensate, speed of sound, and the Critical End Point

Alejandro Rosas Díaz, Alfredo Raya, C. A. Vaquera Araujo +1

The phase diagram of Quantum Chromodynamics (QCD) remains a central topic in high-energy physics. At high temperature and low baryochemical potential, the chiral transition is expe…
