transverse momentum of neutrinos cut

Asked by Elsa

Hello experts,

can you suggest me to do cuts for pt(nu) > 25.0 in run_card.

Thanks

Elsa

If "ptmiss" is not what you need,
then you can use the pt_min_pdg

Cheers,

Hello expert,

I have used the followings:

10.0 = pta ! minimum pt for the photons
  0.0 = misset ! minimum missing Et (sum of neutrino's momenta)
  -1.0 = ptamax ! maximum pt for the photons
  -1.0 = missetmax ! maximum missing Et (sum of neutrino's momenta)
  {'25': 300.0} = pt_min_pdg ! pt cut for other particles (use pdg code). Applied on particle and anti-particle
  {} = pt_max_pdg ! pt cut for other particles (syntax e.g. {6: 100, 25: 50})

but it gives the same cross-section.

Can you help with this problem?
