Hi, let me add 5 cents as BPH MC contact. while this error with EvtGen is expected to be related with generator (fragment, etc), its origin is highly unclear for...

> Last but not least, I would not trust 100% a sample that is generated with a configuration that gives pions no mass ; it might bias the analysis in...

Important thing also is that these failures are hard to reproduce locally ... So this is why I think (maybe naively) why Computing configuration maybe more crucial than the physics...

Hi, I want to confirm that analysers used previously produced similar samples with K0 —> pi pi (mu mu) decays, and they are OK from their point of view it...

Hi, I've launched a CRAB task [250613_145945:kivanov_crab_EvtGen_testKLToMuMu](https://cmsweb.cern.ch/crabserver/ui/task/250613_145945%3Akivanov_crab_EvtGen_testKLToMuMu) for the private GS production of this fragment. There was 100 jobs with 3M events each. We see ([Monit link](https://monit-grafana.cern.ch/d/cmsTMDetail/cms-task-monitoring-task-view?orgId=11&var-user=kivanov&var-task=250613_145945:kivanov_crab_EvtGen_testKLToMuMu&from=1749823185000&to=now)) 96 produced successfully...

Hello, let me share here some recent observations we found for such low filter efficiency MC production with EvtGen: https://gitlab.cern.ch/cms-ppd/dataset-management/simulation-production/-/issues/51 In short, the problem discussed here may be related with...

Hi @davidlange6 , these specific requests are just using `SoftQCD:nonDiffractive = on"` and then PythiaFilter for a kaon presence. So we do not have a b-quark , kaons can be...

Hi all, the current check by @efeyazgan in #3817 `xzgrep "" /eos/cms/store/lhe/'+str(mcdbid)+'/*.lhe | wc -l` does not allow to count the events within ".xz" compressed LHE files — obviously, it...

Hi @bbilin @DickyChant , Could you please kindly take a look to my previous comment? The current check is blocker and makes validation of my new pLHE for 2024 fail,...
