$b$-jet identification algorithms and performance in the ATLAS experiment

Mostrar otras versiones (1)

The identification of $b$-quarks jets ($b$-tagging) is a crucial ingredient in many physics analyses carried out in the ATLAS experiment at the LHC. In this poster, we present the status of b-tagging algorithms and their performance calibration. In particular, new tagging algorithms with improved c-...

description The identification of $b$-quarks jets ($b$-tagging) is a crucial ingredient in many physics analyses carried out in the ATLAS experiment at the LHC. In this poster, we present the status of b-tagging algorithms and their performance calibration. In particular, new tagging algorithms with improved c-jet rejection and extending to high jet pt are discussed, as well as recent improvements and extensions of the performance calibration methods.
