Squark decays: tree-level or one-loop?

[BjHerrmann]

Hi,

I have been looking into the decay modules of SPheno and I have the impression (from simply reading the code) that all decays of squarks are implemented only at the tree-level ?
However, I had in mind that the one-loop diagrams to, e.g., squark -> quark gaugino, were taken into account.

Have I missed something in the code? Or is the calculation indeed tree-level only?
In the same context, what about MFV and NMFV contributions ?

Cheers,
Björn

Hi,

The decays are tree-level but with the most general flavour structure. With Sarah, you can get one-loop decays.

Cheers.
