DerivationFramework: implement self-contained tau thinning, update tau smart slimming list and enable tau thinning in PHYS

Bertrand Martin Dit Latour requested to merge martindl/athena:master_DFTauThinning into master

Hello,

This MR implements a self-contained tool in the DerivationFramework to thin all tau-related containers at once. It replaces the per-container thinning tools used so far. The following containers are thinned: TauJets, TauTracks, InDetTrackParticles, TauNeutralParticleFlowObjects, TauSecondaryVertices, as well as the equivalent "_MuonRM" containers from the muon-subtracted tau reconstruction.

The tau thinning that had been deactivated for easier R21-vs-R22 comparisons is re-enabled. For now, we only require tau pt > 13 GeV. No cut is applied to nTracks nor to the RNN ID score.

The tau smart slimming list has been extended to take advantage of new variables:

  • TauJetsAux.nChargedTracks.nIsolatedTracks.nAllTracks: the first is for convenience, the last two cannot be accessed anymore at DAOD level due to tau track thinning and are useful to understand tau modelling
  • TauJetsAux.NNDecayModeProb_1p0n.NNDecayModeProb_1p1n.NNDecayModeProb_1pXn.NNDecayModeProb_3p0n: tau NN decay mode probabilities, new in R22, the last probability NNDecayModeProb_3pXn can be obtained from unitarity and was not added
  • TauTracksAux.rnn_chargedScore.rnn_isolationScore.rnn_conversionScore: new in R22, again the last score rnn_fakeScore can be obtained from unitarity and was not added

Thanks to the thinning, the size of DAOD_PHYS is kept almost unchanged :-) Numbers taken from 1k ttbar events:

Adding the 'urgent' flag as this is needed for the imminent PHYS production.

Tagging @calpigia , @lfiorini , @dta , @sineadf .

Cheers, Bertrand
