Making an invariant mass cut
Hi Madgraph Team,
How do I make an invariant mass cut (of say 2GeV) in MG5 for a simple drell-yan process such as p p > mm+ mm-? mm is a custom defined particle with custom couplings to the photon and Z boson.
I notice the options in the run card as follows:
#******
# Minimum and maximum invariant mass for pairs *
# WARNING: for four lepton final state mmll cut require to have *
# different lepton masses for each flavor! *
#******
0.0 = mmjj ! min invariant mass of a jet pair
0.0 = mmbb ! min invariant mass of a b pair
0.0 = mmaa ! min invariant mass of gamma gamma pair
0.0 = mmll ! min invariant mass of l+l- (same flavour) lepton pair
-1.0 = mmjjmax ! max invariant mass of a jet pair
-1.0 = mmbbmax ! max invariant mass of a b pair
-1.0 = mmaamax ! max invariant mass of gamma gamma pair
-1.0 = mmllmax ! max invariant mass of l+l- (same flavour) lepton pair
{} = mxx_min_pdg ! min invariant mass of a pair of particles X/X~ (e.g. {6:250})
{'default': False} = mxx_only_
#******
# Minimum and maximum invariant mass for all letpons *
#******
0.0 = mmnl ! min invariant mass for all letpons (l+- and vl)
-1.0 = mmnlmax ! max invariant mass for all letpons (l+- and vl)
#******
Which of these would I have to edit to produce the desired invariant mass cut?
Many thanks,
Ameir
