Generate higgs decays at NLO using SMEFT@NLO

Asked by Massimiliano Galli

Hi, I'm trying to generate events for all the Higgs decay channels using SMEFT@NLO.

What I do is e.g. in the case of H->aa:

import model SMEFTatNLO-NLO
generate h > a a NP=2 QED=1

However, there are cases in which (e.g. H->b b~) I'm not able to generate a valid process (see e.g.

The idea is that, whenever available, I would like to have the computation at NLO, but if it can't be computed then the LO is fine.

Is there somewhere an example in which this task has already been performed, so I can see how to properly generate the processes?

Thank you in advance,

I do not understand your question.
Since this sounds model specific (and that I do not know the details of all the UFO model), maybe the best option is to ask the author of the UFO model how you can can generate the process that you want using their model.



Can you help with this problem?
