001304981 500__ $$aPreliminary results
001304981 520__ $$aA variety of algorithms have been developed, within the ATLAS experiment at the Large Hadron Collider, to distinguish $b$-quark jets from jets containing only lighter quarks. This note describes measurements of the efficiency of the most performant of these $b$-tagging algorithms, as carried out on the data collected at $\sqrt{s}=8$ TeV in 2012, for charm and light-flavour jets. The results, which correct the efficiency in simulation to that measured in data, are presented in the form of jet transverse momentum dependent (and in the case of the light-flavour jets, pseudorapidity dependent) scale factors. Compared to previous calibration analyses, improvements have been made driven by the larger dataset collected in 2012, as well as by a refinement of the existing analyses. These results complement those obtained for $b$ jets as presented in a previous note.
