内容記述タイプ Abstract
内容記述 We propose a new method to investigate the thermal properties of QCD with a small quark chemical potential μ. Derivatives of quark and gluonic observables with respect to μ are computed at μ=0 for two flavors of p4 improved staggered fermions with ma=0.1,0.2 on a 16 3 ×4 lattice, and used to calculate the leading order Taylor expansion in μ of the location of the pseudocritical point about μ=0. This expansion should be well behaved for the small values of μ q /T c ∼0.1 relevant for BNL RHIC phenomenology, and predicts a critical curve T c (μ) in reasonable agreement with estimates obtained using exact reweighting. In addition, we contrast the case of isoscalar and isovector chemical potentials, quantify the effect of μ≠0 on the equation of state, and comment on the complex phase of the fermion determinant in QCD with μ≠0.
