Description
In high-energy elementary particle physics many searches for new physics phenomena, as well as precision measurements in the top quark and Higgs boson sector, rely on the identification of jets originating from b-quarks. This process is also known as b-tagging. The hadrons produced in the decay of b-quarks have characteristics which, within the framework of a detector such as the CMS-detector, can be used to differentiate b-originated jets from other jets. The CMS collaboration has developed various b-tagging algorithms, using multivariate techniques among others, exploiting these characteristics in order to optimize b-tagging. Using 13 TeV proton-proton collision data from CMS, the b-tagging performance has been measured.
