O áxion em condições extremas: matéria de quarks quente e magnetizada, meios densos e estrelas compactas
(Universidade Federal de Santa Maria, 2023-07-31)
We investigate the phase diagram of quantum chromodynamics by means of the Nambu-
Jona-Lasinio effective model, including the axion - a particle which emerges as a solution
of the strong charge-parity (CP) problem and ...
Termodinâmica e transições de fase existentes na matéria de quarks com desbalanceamento quiral
(Universidade Federal de Santa Maria, 2023-07-01)
In this dissertation, we have used effective models, such as the Nambu-Jona-Lasinio (NJL)
and the Polyakov–Nambu–Jona-Lasinio (PNJL) to describe and study the Quantum Chromodynamics (QCD) phase diagram with chiral imbalance. ...
