Description
Numerical monte carlo study of lattice discretized QCD is the only
non-perturbative tool available for calculation of the equation of
state of strongly interacting matter from QCD at not-too-high
temperatures. Unfortunately, these numerical tools are not directly
applicable at finite baryon densities, as is required for, e.g., the
beam energy scan studies.
Using the method of Taylor expansion in chemical potential, we
estimate the equation of state of strongly interacting matter, namely
the baryon number density and its contribution to the pressure, for 2-flavor
QCD at not-too-high chemical potential. We also report the isothermal
compressibility. We examine the technicalities associated with summing
the series. We also study the quark number susceptibilities to gain
insight into properties of strongly interacting matter at high temperatures.
