Three regimes/phases of QCD at high T, their symmetries and N_c scaling
TLDR
This paper reviews three distinct QCD phases at high temperatures, characterized by different symmetries and N_c scaling.
Key contributions
- Identifies three distinct QCD regimes at high temperatures and small chemical potentials.
- Characterizes each regime by its unique symmetries, degrees of freedom, and N_c scaling.
- Details the hadron gas below T_ch, stringy fluid between T_ch and T_d, and quark-gluon plasma above T_d.
Why it matters
This paper offers a crucial review of the QCD phase diagram at high temperatures, detailing three distinct regimes. Understanding these phases—hadron gas, stringy fluid, and quark-gluon plasma—is vital for theoretical physics, as it clarifies their unique symmetries and N_c scaling.
Original Abstract
We review recent developments on the QCD phase diagram at small chemical potentials and increasing temperature. There are three regimes/phases in QCD which differ by symmetries, degrees of freedom and N_c scaling: the hadron gas below the chiral restoration temperature T_ch, the stringy fluid between T_ch and the deconfinement temperature T_d and the quark-gluon plasma above T_d.
