Description
We discuss the distribution of the quark number over the gauge fields
for QCD at nonzero quark chemical potential. As the quark number
operator is non-hermitian, the distribution is over the complex
plane. Moreover, because of the fermion determinant,
the distribution is not real and positive. The computation
is carried out within leading order chiral perturbation theory and
gives direct insight into the delicate cancellations that take place
in contributions to the total baryon number.
