We propose a new method to investigate the thermal properties of QCD with a small quark chemical potential. Derivatives of quark and gluonic observables with respect to are computed at =0 for two flavors of p4 improved staggered fermions with ma=0. 1, 0. 2 on a 16^34 lattice, and used to calculate the leading order Taylor expansion in of the location of the pseudocritical point about =0. This expansion should be well behaved for the small values of ₐ/T₂0. 1 relevant for BNL RHIC phenomenology, and predicts a critical curve T₂ () 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 0 on the equation of state, and comment on the complex phase of the fermion determinant in QCD with 0.
