Performance of b tagging algorithms in proton-proton collisions at 13 TeV with Phase 1 CMS detector

Many measurements as well as searches for new physics beyond the standard model at the LHC rely on the efficient identification of heavy flavour jets, i.e. jets containing b or c hadrons. In this Detector Performance Summary, the performance of these algorithms is presented, based on proton-proton collision data recorded by the CMS experiment at 13 TeV. Expected performance of the heavy flavour identification algorithms with the upgraded tracker detector are presented. Correction factors for a different performance in data and simulation are evaluated in 41.9 fb-1 of collision data collected in 2017. Finally, the reconstruction of observables relevant for heavy flavour identification in 2018 data is studied.
