The measurement of B-hadrons lifetime

The main purposte of this page is to keep all locationsof data and codes.

Bd Lifetime

The Bd events are stored in the BPHY10 derivation.

possible background: B0 s → J/ψ K∗0 (5366 MeV)

Derivations:

The containers for years 2016-17 were not prepared and since many files are missing the re-reconstructioin of these files is needed.

2015:

2016:

2018:

Ntuples:

The ntuple making code is stored in the repository https://gitlab.cern.ch/ranovotn/bdxaodanalysis

This is unofficial code derived from Bs ntuples making code (on BPHY5).

Just note that in 2015 data the Bd containter was named as "BdJpsiKstCandidates" while for the later data it was renamed to the "BPHY10BdJpsiKstCandidates"

B+ Lifetime

The B+ lifetime use BPHY5 derivation which is common for the BsJpsiPhi analysis.
