Draft: New LLP->eta pi pi line
Introduce a new line in the LLP2Hadrons
builder, which selects LLP->eta pi pi
where eta
decays to two photons.
Other lines from the module were not included in the restripping of 2017 data - aiming at rerunning the entire module for 2017.

Hi @ausachov , the pipeline is not fully launched, could you please change your branch name as 'QEE_Physicsinfo_2018-patches'
And could you also add the info of
StrippingLLP2Hadrons_EtaPiPi_gg_LongLine
andStrippingLLP2Hadrons_EtaPiPi_gg_DownLine
, not only the_TIMING
lines.Edited by Xiaolin Wang
changed milestone to %2023 Re-Strip Campaign -- Development and Testing
added QEE label
requested review from @xiaolinw
assigned to @ausachov
@ausachov Could you please up the stats of the test, since these are very close to threshold. A test with 100k events would be greatly appreciated.
I have one question here: all the other lines in
LLP2Hadrons
module were running in the previous restripping of 2018 data (with the same configs), but not 2017 and 2016. Does it change anything for this MR? @ngrieser @xiaolinwEdited by Andrii UsachovI see many LLP2Hadrons lines running the most recent 2016 restripping: http://lhcbdoc.web.cern.ch/lhcbdoc/stripping/config/stripping28r2p1/index.html I don't see them in 2017
