Abstract
It is shown that gluonic corrections to the tadpole diagrams vanish in the two-flavor color superconducting and in the color-flavor locked phase at the order where one might have expected next-to-leading order corrections. This implies that the gluonic part of the color charge density is negligible at the order of my computation. This statement remains true after inclusion of the gluon vertex correction and contributions from Nambu-Goldstone bosons.
