SubProcesses doesn't have available phase-space
Dear Experts,
I am using the following UFO model which violate baryon and lepton numbers with MG5_aMC_v2_6_5.
https:/
for generating event I use the following commands
import model bnv-ufo
generate p p > t~ ta+
and when I launch I receive the following error
Command "launch" interrupted with error:
ALOHAERROR : Unable to deal with 4(or more) point interactions
in presence of majorana particle/flow violation
Please report this bug on https:/
More information is found in 'MG5_debug'.
Please attach this file to your report.
If I comment the following lines in the MG5_aMC_
# if not data == target:
# text = """Unable to deal with 4(or more) point interactions
#in presence of majorana particle/flow violation"""
# raise ALOHAERROR, text
my first question is whether commenting these lines are OK? does it have any negative effect?
My second question is regarding the error I see by adding one jet to the process. If I run
import model bnv-ufo
generate p p > t~ ta+ j
I see the following error

I read this thread

but it seems everything is updated in MG5_aMC_v2_6_5. I also checked with MG5_aMC_v3_1_0 but I see the same error.
I checked process by process, it seems MG has problem with processes that are initiated by gluon-quark interactions.
Please let me know if any information is needed from my side.
Thanks a lot,
Reza
