Partially quenched QCD with a chemical potential

Using a chiral random matrix theory we can now derive the low energy partition functions and Dirac eigenvalue correlations of QCD with different chemical potentials for the dynamical and valence quarks. The results can also be extended to complex (and purely imaginary) chemical potential. We also discuss possible applications such as fitting to low energy constants and understanding the phase diagrams of the full and partially quenched theories.
