Pull request overview
This PR extends the HH→bbWW Run 3 analysis configuration to start studying inclusion of bbττ signal samples by adding the corresponding datasets/processes and enabling XtoHHto2Tau2B as a signal in the Run 3 and production physics models.
Changes:
- Add
XtoYHto2B2Tauand/orXtoYHto2Tau2Bdataset definitions across Run3 eras (2022, 2022EE, 2023, 2023BPix, 2024). - Add new meta-processes for
XtoHHto2B2Tau/XtoHHto2Tau2Bin the per-eraprocesses.yaml. - Update
Run3_ModelandProduction_Modelto includeXtoHHto2Tau2Bas a signal, and skip bbWW-specific gen signal variables for the ττ signals in anatuple production.

2B2Tau samples are not lepton specific, and are set to be plotted for all channels

@kandrosov ready for review (again), I responded to the robot comments. |
It was seen that the Run 2 analysis and data cards include HH_bbtt as a signal. This increases signal yield by roughly 25% across all masses in the Run 2 analysis.

To start the investigation on adding bbtautau signals, this PR adds the datasets, processes, and physics model to use them as signal in the production and the Run3_Model.
It is also seen that the DAS has 2 forms of most YH samples. "YHto2B2Tau" and "YHto2Tau2B". These are seen to force decays in Y/H. For 2B2Tau, era 2023 is missing some mass points, so the physics model will only use 2Tau2B.
