An Abelian Ward identity and the vertex corrections to the color superconducting gap
arXiv:0810.2168 · doi:10.1088/1674-1137/33/9/008
Abstract
We derive an Abelian-like Ward identity in color superconducting phase and calculate vertex corrections to the color superconducting gap. Making use of the Ward identity, we show that subleading order contributions to the gap from vertices are absent for gapped excitations.
