Aspects of the thermal phase transition of QCD with small chemical potential

Abstract

We propose a new method to investigate the thermal properties of QCD with a small chemical potential $(\mu )$. The derivatives of the phase transition point with respect to $\mu$ are computed for 2 flavors of p4-improved staggered fermions. We moreover comment on the complex phase of the fermion determinant in finite-density QCD.
