Calculation of Wilson Coefficients in SPheno

[FStaub]

Hi,

there has been a change in

FlavorKit/QFV/Operators/Gluon2Q.m

and the external particles are re-ordered. That has happened already in version 4.10.0. However, I must admit that I'm right now not totally sure what the reason for this was. I need to check old notes...

Best,
Florian

Hi Florian,

this reordering seems to be rather unconventional to me.
Can you please check your old notes for the reason because i can not think of
any cause for this.

Hi,

I discussed this also with Avelino and it seems that this change was not intended. (Espeially since the corresponding photon process hasn't been changed and also the numbers seem not to fit anymore).
We will move back to the old version in the next update. Thanks for finding this issue and sorry for the trouble.

Cheers,
Florian

Hi Florian,

thanks for appreciating my comment

Can you tell me in which basis SPheno works, when generation mixing is turned on?
I first thought it takes the input in the SuperCKM basis, but then i saw this SCKM flag in the settings
so i don't know for sure how the squark mass matrices are evaluated.

Hi,

for the MSSM, the SCKM matrix is kind of hard-coded. It can be used for the in- and output when flag 51 is set. Otherwise, everything is done in the mass basis.
