15 Nov 2015 | | Abstract: | In a previous paper (JHEP {f 05} (2014) 27), we calculated the three-loop
thermodynamic potential of QCD at finite temperature $T$ and quark chemical
potentials $mu_q$ using the hard-thermal-loop perturbation theory (HTLpt)
reorganization of finite temperature and density QCD. The result allows us to
study the thermodynamics of QCD at finite temperature and isospin chemical
potential $mu_I$. We calculate the pressure, energy density, and entropy
density, the trace anomaly, and the speed of sound at zero and nonzero $mu_I$.
The second, fourth, and sixth-order isospin susceptibilities are calculated at
zero $mu_I$. Our results can be directly compared to lattice QCD without
Taylor expansions around $mu_q=0$ since QCD has no sign problem at finite
isospin chemical potential. | | Source: | arXiv, 1511.4660 | | Services: | Forum | Review | PDF | Favorites | |
