Guess Feature Not Working
I'm trying to use Pythia's guess
feature for the CKKW-L merging, but it looks like this doesn't get picked up properly and defaults to using pp>e+e-
for the merging process somehow.
I have this in my pythia card:
Merging:Process = guess
Yet I see this in the Pythia log:
*------------------ MEPS Merging Initialization ------------------*
| |
| CKKW-L merge |
| pp>e+e- with up to 2 additional jets |
| Merging scale is defined in kT, with value ktMS = 15.000 GeV
| |
*-------------- END MEPS Merging Initialization ------------------*
and confirmed later on here:
| Name | Now | Default Min Max |
| Merging:Dparameter | 0.40000 | 1.00000 |
| Merging:mayRemoveDecayProducts | on | off |
| Merging:nJetMax | 2 | 0 0 |
| Merging:nQuarksMerge | 4 | 5 2 5 |
| Merging:Process | pp>e+e- | void |
| Merging:TMS | 15.00000 | 0.0 |
For what it's worth, I'm using gitlab-registry.cern.ch/scipp/mario-mapyde/madgraph-2.9:master
