g-2 in SPheno
Hi, Does somebody know how to interpret the value of the anomalous magnetic momenta listed in SPheno spectrum files? For example, running the SM implementation in SARAH produces the following line for muon g-2: 21 2.07281881E-14 # (g-2)_mu This is many orders of magnitude too small to be the SM valu...

Re: Implementing a flavour-changing neutral current
Update: I made quite some headway using the second approach above. After I included all intergenerational Yukawa couplings in the Lagrangian, i.e. non-diagonal ones in addition to the ones in the post above, the model runs all the way through SARAH and SPheno and reproduces SM results IF I add the S...

Implementing a flavour-changing neutral current
Dear experts, I am working to implement a flavour-changing neutral current (FCNC) between the b and s quarks at tree level in SARAH. To do this, I am trying to figure out the best way to "flavour-decompose" the quark fields in SM.m so that I can eventually make two flavours oppositely charged under ...
