Applying cuts on run_card does not seem to change anything

hi,

In none of those two processes you have lepton on the final state.
So again, the cut will have no impact.

Additionally since you use the decay chain syntax, you have to be aware of the value of the
cut_decays paramater which allows to bypass cuts on particles orignated from a decay.

Cheers,

Olivier
