CMS Phase 1 heavy flavour identification performance and developments /CMS Collaboration
At the Large Hadron Collider, the identification of jets originating from heavy flavour quarks (b or c tagging) is important for searches for new physics and for measurements of standard model processes. A variety of b tagging algorithms has been developed at CMS to select b-quark jets based on variables such as the impact parameters of the charged-particle tracks, the properties of reconstructed decay vertices, and the presence or absence of a lepton, or combinations thereof.

Performance of heavy flavour identification algorithms in proton-proton collisions at 13 TeV at the CMS experiment /CMS Collaboration
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. [...]
