Phase diagram of chiral 2-flavor QCD based on an effective approach
Edgar López-Contreras, José Antonio García-Hernández, Elías Natanael Polanco-Euán +1
Despite intense experimental and theoretical research, the QCD phase diagram at finite baryon density remains to a large extent unexplored. From the theoretical side, the obvious n…
The 3d O(4) model as an effective approach to the QCD phase diagram
Edgar López-Contreras, José Antonio García-Hernández, Elías Natanael Polanco-Euán +1
The QCD phase diagram is one of the most prominent outstanding puzzles within the Standard Model. Various experiments, which aim at its exploration beyond small baryon density, are…
Conjecture about the QCD phase diagram
José Antonio García-Hernández, Edgar López-Contreras, Elías Natanael Polanco-Euán +1
We present a phase diagram study of the O(4) model as an effective theory for 2-flavor QCD. In the chiral limit, both theories perform spontaneous symmetry breaking with isomorphic…
