Abstract
The correct identification of jets containing b hadrons (hence b-tagging) is of capital importance for the hadron collider experiments, such as ATLAS and CMS at the Large Hadron Collider. In particular, b-tagging is an important tool for many physics analyses: for top quark studies and Higgs boson searches, as well as the search for new physics fenomena beyond Standard Model. ATLAS developed its own algorithms for b-jet identification, exploiting the typical properties of the b quarks and the B hadrons emerging from the jet: the long lifetime, the high decay multiplicity and the high invariant mass above all. The status of the most recent b-tagging algorithms developed by the ATLAS experiment is presented, along with the methods used to measure the b-tagging efficiency on a charm jets sample at 13TeV with 2015 data.
