13 Apr 2017 | | Abstract: | We investigate the potential for using the canonical ensemble approach to
determine the QCD phase diagram in the temperature - density plane. This
approach allows us to study the finite baryon density regions where the
well-known sign problem obstructs the standard lattice QCD numerical study.
Using the canonical ensemble approach, we perform lattice QCD simulations at
the pure imaginary quark chemical potential. In this case no sign problem
occurs. We then calculate physical quantities at the real chemical potential
through the canonical partition functions.
In this approach, the canonical partition functions, $Z_n$, play an essential
role for mapping the information from the pure imaginary chemical potential
values to the real ones. We analyze how inaccuracies in the numerical data
obtained at the imaginary chemical potential affect the results for the real
values, where the QCD predictions confront experimental quark-gluon plasma
(QGP) data.
We compute the higher moments of the baryon number including the kurtosis and
compare our results with information from relativistic heavy-ion collisions. | | Source: | arXiv, 1704.3980 | | Services: | Forum | Review | PDF | Favorites | |
