Abstract
We have studied how large repulsive Coulomb pseudopotential μ* values might affect various superconducting thermodynamic properties and the upper critical magnetic field in the clean and dirty limit. Existing approximate analytical expressions for these properties derived from Eliashberg theory were generalized to include a μ*/λ correction term. The μ*/λ corrections for the various superconducting properties were found to enhance rather than diminish strong-coupling effects.
