[Backport 7_1_X] Fix EmissionVetoHook for BB4L

[lauridsj]

PR description:

This is a backport of #42264, fixing the Pythia EmissionVetoHook for BB4L, to CMSSW 7_1_X. This is needed for the ttbar spin entanglement analysis, which uses preLegacy 2016 data. For this analysis, a sample with the Powheg process "ttb_NLO_dec" is needed for a cross-check. This process has the same final state as BB4L (up to three real emissions) and thus uses the same hook.

PR validation:

See #42264.

If this PR is a backport please specify the original PR and why you need to backport that PR. If this PR will be backported please specify to which release cycle the backport is meant for:

Backport of #42264, as written above.

@mkirsano, @alberto-sanchez, @bbilin, @GurpreetSinghChahal, @SiewYan, @menglu21, @cmsbuild can you please review it and eventually sign? Thanks.
@mkirsano, @alberto-sanchez this is something you requested to watch as well.
@rappoccio, @antoniovilela, @sextonkennedy you are the release manager for this.

@cmsbuild please test

[agrohsje]

hi @RSalvatico @perrotta , can you advise on how to solve the missing IB problem? thanks.

hi @RSalvatico @perrotta , can you advise on how to solve the missing IB problem? thanks.

Maybe @smuzaffar can create a 7_1_X IB only for this purpose.
Or maybe the release managers (@rappoccio and @antoniovilela ) can decide to merge this simple PR without testing it, possibly after it will have been discussed in a ORP meeting.

[smuzaffar]

I need to enable add 7.1.X IBs otherwise you will not be able to build the release.
I will get back to you once 7.1.X IBs are available.

[smuzaffar]

please test

Dear @smuzaffar , how should we proceed with the problems above? Thanks, Alexander.

[smuzaffar]

@agrohsje , tests are failing for 7.1.X IBs , I think data for wf 4.22 is still available but wf 25202.0 data (/RelValTTbar_13/CMSSW_7_1_14-MCRUN2_71_V1-v1/GEN-SIM) is not available ( das client does not return any thing for this).

I would suggest to ignore the tests results here

[agrohsje]

Thanks! @menglu21 @bbilin Please check and sign. Thanks!

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_1_X IBs (but tests are reportedly failing) and once validation in the development release cycle CMSSW_13_3_X is complete. This pull request will now be reviewed by the release team before it's merged. @rappoccio, @sextonkennedy, @antoniovilela (and backports should be raised in the release meeting by the corresponding L2)

[agrohsje]

Dear @RSalvatico, can we get a new 7_1 release? We need them urgently for some pre-legcay 2016 top pag analysis.

Hello, I'm afraid you are tagging the wrong person :) Though I am not sure who you meant to ping, so I cannot forward the ping myself.

[agrohsje]

Sorry for the wrong tag. My mistake. I wanted to ping @rappoccio @antoniovilela:
Can we get a new 7_1 release? We need them urgently for some pre-legcay 2016 top pag analysis.

[rappoccio]

@smuzaffar Is it possible to even build this release? @jordan-martins and @malbouis are checking if there are even pileup libraries available to do this.

@agrohsje we usually reserve "urgent" for datataking issues, a pre-legacy 2016 MC sample is not really what we would refer to as "urgent".

[smuzaffar]

yes @rappoccio , bot is able to build the IB so it should be able to build the release

[agrohsje]

Hi @rappoccio. The analysis is the answer from CMS on the entanglement observation of ATLAS. Target here is end of November, hence the time pressure and the increased priority. If this is technically still possible, having 2 more samples in 7_1 with the bug fix above would be of great help. Let me know.

Hi @agrohsje, we will merge it and attempt to build the release later this week. If needed more urgently than this (we have a queue of releases to be built), please go through PPD to pass along the request.

Thanks for 7_1_48! Just saw the announcement. Really great.
