Dear all,
I tried looking in all other similar questions but did not find any solutions there.
I am using a BSM model where I am introducing three additional scalars with charges (SU3 x SU2 x UY1):
six1: (6bar, 1, 4/3 )
six2: (6bar, 1, -2/3 )
six3: (1, 1, -2 )
Anyways, while using
generate p p > six2, (six2 > six1 six3, (six1 > u u), (six3 > e- e-))
I got as error:
******************************************************************************************
P1_dd_six2_six2_six1six3_six1_cc_six3_emem,P1_ss_six2_six2_six1six3_six1_cc_six3_emem SubProcesses doesn't have available phase-space.
Please check mass spectrum.

However, masses for scalars are:
six1: 600 GeV
six2: 2200 GeV
six3: 600 GeV
I tried to isolate the problem, but all parts of the process spit out a cross section independently. For instance, the following processes work:
generate p p > six2, (six2 > six1 six3)
generate six1 > u u
generate six3 > e- e-
I am using version 3.4.1. I tried to use 2.9.13 as well, but got the same error.
I was wondering whether someone has any idea why my generation is not working. I thank you all in advance!
Best regards,
