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

PR description:
Following up on PR #43918, the newly introduced mass-dependent uncertainty on the time of flight of tracks has been propagated to the following reconstruction steps. This additional contribution to track time uncertainty is now:
TrackExtenderWithMTD
;VertexTimeAlgorithmFromTracksPID
vertex time algorithm for the 3D+t step, which now uses a different track time uncertainty for each mass hypothesis;TOFPIDProducer
(used in the 4D vertex reconstruction step throughDAClusterizerInZT
andVertexTimeAlgorithmLegacy4D
).Furthermore, an improved definition of vertex time uncertainty has been introduced in both
VertexTimeAlgorithmFromTracksPID
andVertexTimeAlgorithmLegacy4D
.All the mentioned modifications have been discussed and presented in MTD DPG meetings (1, 2).
PR validation:
The PR has been validated on TTbar14TeV and TTbar14TeV+PU200 samples, producing results documented in the two aforementioned presentations.
