Abstract

Addition of a chemical potential to the standard lattice action for QCD results in a fermion determinant which is no longer a positive real number, making numerical computations of the path integral much more difficult. I present preliminary results for QCD on 4⁴ lattices with four flavors of staggered quarks and discuss the technical problems encountered.
