Re: EDM calculation: ecmfactor

Hi Marrit

Did you manage to solve this?

I had a similar issue with EDMs off by a factor

One loop mass spectrum

Hi everyone I was wondering if you could point me in the direction of how to extract the one-loop mass spectrum from the SPheno output file, or (if this is as obvious as extracting from Block MASS) help me to decipher why I am never getting a correction to the mass of the SM fermions. To give contex...

Re: WC JSON vs WC in SPheno output

Hi Florian I have tried to look at the output from SPheno.spc, but when i plot the NP contribution it appears to asymptote to a non-zero number in the limit of the mediator mass ---> inf. Perhaps I am just unaware of the normalisation for C9 in FLHA. Resources on FLHA basis appear to be scarce for o...

Re: WC JSON vs WC in SPheno output

Hi there, My program takes as input the WC_... .json file, feeds it to flavio and runs the WCs to the 4.2 GeV scale and evaluates them. When i look at the Flavio output of C9 -- it appears to asymptote to a finite value rather than zero as I increase the scalar mediator mass. This doesn't seem to be...

Re: WC JSON vs WC in SPheno output

To clarify, this b-> c vector coupling issue is still unsolved.

Re: WC JSON vs WC in SPheno output

Hi, the basis for the FlavorKit and SPheno codes can be found here: https://wcxf.github.io/assets/pdf/WET.FlavorKit.pdf Does that clarify the issue for the b -> c tau nu processes? Hi Avelino, It's not a misunderstanding of the basis, but rather that I am never able to obtain a nonzero value for th...

Re: WC JSON vs WC in SPheno output

Hi Florian Is there a similar issue with the definition of couplings contributing to b to c tau nu? I am inputting effective interactions that should be contributing to the cbtaunu effective operators but these are only ever writing out as zero: "GVLL_3213": { "Re": 0.0000000000000000 , "Im": 0.0000...

Re: WC JSON vs WC in SPheno output

Hi Florian, Now when I try and use the Wilson package to load the json file for use in Flavio the following error: "Wilson coefficients do not exist in this basis: " + str(unknown_keys) AssertionError: Wilson coefficients do not exist in this basis: {'EVLR_3233', 'EVLR_3211', 'EVLL_3211', 'EVLL_3222...

WC JSON vs WC in SPheno output

Hi, I'm working on a Leptoquark model with Sarah+Spheno, and whilst it appears that the Wilson coefficients in the SPheno.spc are evolving in the expected way with changes in my model parameters, this doesn't appear to be true of the WCs in the json files. In particular, I am looking at C9 for b \to...
