Different definitions of the chemical potential with identical partition function in QCD on a lattice
arXiv:hep-lat/0210045 · doi:10.1103/PhysRevD.69.074508
Abstract
It is shown that starting from one and the same transfer matrix formulation of QCD on a lattice, it is possible to obtain both the action of Hasenfratz and Karsch as well as an action where the chemical potential is not coupled to the temporal links.
