Pythia 8 stucks on shower jobs
Hi!
I am trying to simulate the processes
generate process p p > h [noborn=QCD]
add process p p > h j [noborn = QCD]
and then to interface it to pythia for showering and hadronization. pythia6 runs fine, while pythia8 stucks on shower job (as far as I can wait).
The parameters regarding matching/merging in the run_card.dat are
1 = ickkw ! 0 no matching, 1 MLM
1.0 = alpsfact ! scale factor for QCD emission vx
False = chcluster ! cluster only according to channel diag
4 = asrwgtflavor ! highest quark flavor for a_s reweight
False = auto_ptj_mjj ! Automatic setting of ptj and mjj if xqcut >0
30.0 = xqcut ! minimum kt jet measure between partons
I also tried to set the parameters in pythia8_card.dat manually:
qcut=45
Merging:nJetMax = 2.
The terminal output when launching is the following:

| 3. Choose an analysis package (plot/convert) analysis = ExRoot |
| 4. Decay onshell particles madspin = OFF |
| 5. Add weights to events for new hypp. reweight = Not Avail. |

Either type the switch number (1 to 5) to change its setting,
Set any switch explicitly (e.g. type 'shower=Pythia6' at the prompt)
