error:invalid particle format while hadronisation in Pythia
Dear experts,
I was trying to generate vbf process and shower and hadronise with Pythia using my model file as follows:
define v = w+ w- z
define uq = u c d s t b
generate p p > h j j $$v /a g h uq NP=0 SMHLOOP=0, h > a a NP=0, SMHLOOP=1
The SMHLOOP interation is an effective one between higgs and photons. As showering and hadronisation is occuring, I get the following error:

The process is completed. But I am not sure if it completely hadronised the events or not. Could you please explain this error and tell if the process is hadronised or not?
