Gauge dependence identities for color superconducting QCD
arXiv:hep-ph/0305108 · doi:10.1103/PhysRevD.68.011502
Abstract
Using generalized Nielsen identities a formal proof is given that the fermionic quasiparticle dispersion relations in a color superconductor are gauge independent. This turns out to involve gluonic tadpoles which are calculated to one-loop order in a two-flavor color superconductor. Regarding the appearance of gluon tadpoles, we argue that in QCD the color superconducting phase is automatically color neutral.
