is subdecay of three particles possible?
Asked by
pietro govoni
Dear Madgraph gurus,
when trying to generate the following LO process:
generate p p > w+ w- z / h, (w+ > q q, w- > lep nus, z > b b~) QED=6 QCD=0
I get the error message that:
WARNING: Decay without corresponding particle in core process found.
Decay information for particle(s) w+,z is discarded.
Please check your process definition carefully.
This warning usually means that you forgot parentheses in presence of subdecay.
Example of correct syntax: p p > t t~, ( t > w+ b, w+ > l+ vl)
Does this mean that more than two subdecays cannot be listed in parentheses, or am I missing something else?
Best regards,
pietro
