Phys. Rev. D 68, 011502(R) (2003) [5 pages]Gauge dependence identities for color superconducting QCD
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. © 2003 The American Physical Society URL:
