jet algorithm at parton level

Hi,

Do you want to compute LO or NLO type of cross-section.
For NLO type of cross-section, you can directly specify the clustering algorithm in the run_card.
This is not possible in the LO module.

If you are interested in the LO part, one trick is to go trough the NLO module and ask to compute the LO cross-section.
This will allow you to have the exact same setup as the NLO one and you would therefore be able to choose the clustering algorithm.
(one more trick is to use the [LOonly=QCD] flag to avoid the need to generate the loop/real since you actually do not care about them)

Cheers,

Olivier

I would like to make exactly the same setup between the two programs and would need to apply anti-kt jet algorithm at parton level. I am not sure if there is a way to set this up in the runcard. Please advice, thanks!

Thank you very much Olivier! That should solve the issue I am facing.

Best wishes,
