Explicit expressions for the specific heat discontinuity of a two-band superconductor containing Anderson impurities are derived by means of diagrammatic techniques. Both interband and intraband contributions are treated. The results contain the already known limiting cases: the BCS, pure two-band,
We study the effect of a constant hybridization V 0 in the specific heat jump DC at the superconducting critical temperature T c , dealing with an exact analytical expression obtained from the extended BCS gap equation. Our model is suitable to discuss a superconducting material described by a hybri
