b-Tagging in Proton Collisions at 13 TeV using the 2016 Data

At the Large Hadron Collider, the identification of jets originating from b quarks is important for searches for new physics and for measurements of standard model processes. A variety of algorithms has been developed by 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. This note presents some distributions of these variables with the data recorded in 2016 at a center-of-mass energy of 13 TeV, corresponding to a total integrated luminosity of 0.8/fb.
