Tau decay products in NanoDQM

[Ksavva1021]

PR description:

This PR adds tau decay product information in NanoAOD. A collection of tau decay products is created on the fly and then stored in a new NanoAOD table. Additional information stored is as follows for each candidate in the table:

• 3-momenta
• PDG ID
• Index of its mother tau

Size tests have been conducted to assess the size increase on NanoAOD. These tests have been conducted using two RelVal samples:

• TTBar (/w PU)
• ZTT

The cumulative contribution of the tau decay products in NanoAOD is expected to be around 1.3 % (TTBar) and 2% (ZTT). Breakdowns are available here.

This PR also allows the tau decay products to be monitored by NanoDQM.

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:

This PR is a backport of PRs #42987 & #43382

A new Pull Request was created by @Ksavva1021 (Klitos Savva) for CMSSW_13_2_X.

It involves the following packages:

• PhysicsTools/NanoAOD (xpog)
• PhysicsTools/PatAlgos (xpog, reconstruction)

@jfernan2, @cmsbuild, @mandrenguyen, @vlimant, @simonepigazzini can you please review it and eventually sign? Thanks.
@seemasharmafnal, @mbluj, @emilbols, @demuller, @JyothsnaKomaragiri, @hatakeyamak, @AlexDeMoor, @andrzejnovak, @ahinzmann, @gkasieczka, @Ming-Yan, @gouskos, @gpetruc, @azotz, @mariadalfonso, @nhanvtran, @rappoccio, @Senphy, @jdamgov, @mmarionncern, @AnnikaStein, @jdolen, @schoef this is something you requested to watch as well.
@sextonkennedy, @rappoccio, @antoniovilela you are the release manager for this.

Adding @mbluj as a watcher

[vlimant]

enable nano

[vlimant]

this backport to 13.2 does not seem necessary to me, unless this was already in 13.0.X

No, it was not in 13_0. We just wonder which release is going to be used for nano v12 as we would like to have this development in it.

[mandrenguyen]

unassign reconstruction
since it only relates to nano, this is xpog business

[mandrenguyen]

+reconstruction
Not sure why unassigned didn't work, so I'll just sign

[vlimant]

please test

[vlimant]

v12 is with 13.0 and is closed. if this goes in 13.3, then it will be in the upcoming v13

[mbluj]

v12 is with 13.0 and is closed. if this goes in 13.3, then it will be in the upcoming v13

Yes, right. It was mistype, I meant v13... So, indeed there is not need to backport to 13_2

This pull request is fully signed and it will be integrated in one of the next CMSSW_13_2_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_14_0_X is complete. This pull request will now be reviewed by the release team before it's merged. @antoniovilela, @rappoccio, @sextonkennedy (and backports should be raised in the release meeting by the corresponding L2)
