bibo_abstract:
- We present results of a simulation of QCD on a 4x16^3 lattice with 2 continuum
flavors of p4-improved staggered fermion with mass m/T=0.4. Derivatives of the
thermodynamic grand potential with respect to quark chemical potential mu_q up
to fourth order are calculated, enabling estimates of the pressure, quark number
density and associated susceptibilities as functions of mu_q via Taylor series
expansion. Discretisation effects associated with various staggered fermion formulations
are discussed in some detail. In addition it is possible to estimate the radius
of convergence of the expansion as a function of temperature. We also discuss
the calculation of energy and entropy densities which are defined via mixed derivatives
of the thermodynamic grand potential with respect to the bare couplings and quark
masses.@eng
