Yukawa couplings with extra vector-like leptons
Dear Florian, I am analysing a simple toy model where new vector-like leptons could have a sizeable mixing with the Standard model ones. Eventually, Spheno always outputs the exact masses for the Standard Model leptons, hence I would expect that the leptons Yukawa couplings are determined on-the-fly...

Normalisation B to Kll - FlavorKit
Dear Florian, I know you did some changes for this particular decay a year ago, but I am wondering if the normalisation of the contribution for the C7 coefficients does not miss an (4pi alpha) factor. The reason is the following: - FlavorKit uses CC7 for both B->Kll (based on 1308.1501, correcting t...

Numerical divergences in Box Diagrams for FlavorKit
Dear Florian, When using FlavorKit to calculate low energy observables, numerical divergences are reported in the Message.out file from SPheno. They concern D00check, D0C0check and B0. They seem to be related to box loops involving the pseudo-scalar eigenstates. I can see them appearing in different...
