MC request using splitSim to study different decay modes with converted photons

Requires the use of

$APPCONFIG/options/Gauss/SplitSim-GammaConversionFilter.py https://gitlab.cern.ch/lhcb-datapkg/AppConfig/-/blob/v3-patches/options/Gauss/SplitSim-GammaConversionFilter.py and $APPCONFIG/options/Gauss/GammaConversionFilter_ExtendZ.py https://gitlab.cern.ch/lhcb-datapkg/AppConfig/-/blob/v3-patches/options/Gauss/GammaConversionFilter_ExtendZ.py?ref_type=heads

FYI : the production will pass through the RD group , CC'ed @elsmith , @abiolchi , @rihender

THe production is across different channels :

• Bs-> Phi gamma
• B0 -> K* gamma
• Lb-> L gamma
• B+ -> K+ pi0 ( to verify we could gain something in pi0 -> gg )

The SplitSim with the conversion at Z < 2400 has a retention rate of 20% in Gauss, so i scaled 2M generated events by a factor 4. All samples to be generated DST since it would be useful to study also some 'restripping' dedicated to those decays.

As i am new to the request, which field has to be added to the yaml to specify this is SplitSim and the additional AppConfig has to configured @adavis ?

Requires lbmcsubmit!66 (merged)

added RD label

@rquaglia see lbmcsubmit!66 (merged) . Once reviewed and merged, you should be able to use in the yaml file

fast-mc:
  splitsim: yes

The MR should be ok, i tried to test the yaml with

lb-mc converted_gamma_request_stage0.yaml converted_gamma_request_stage6.yaml
Loading converted_gamma_request_stage0.yaml
Running checks
Generated 6 production requests
    containing 24 subrequests
    and 192,000,000 events

Is this the correct way to do this? Should i rename the file to be _stage0?

Hello, is there anything i should be doing in this? I would need those samples to verify some new stripping lines i am planning to develop for the restripping campaign.

Thanks in advance for any feedback
