B-tagging calibration using ttbar events / Leyko, A (University of Bonn)
Many physics analyses with the ATLAS detector expect to have jets originating from b-quarks. Algorithms that allow to identify those jets are thus of great importance and it is crucial to understand their performance. [...]

Measurement of the b-tagging performance of the ATLAS detector / Tannoury, N
The identification of jets originating from b-quarks, referred to as b-tagging, is an important part of the LHC physics program. Most b-tagging algorithms exploit the relatively long lifetime of the b-hadron, resulting in a second decay vertex which is significantly displaced from the primary interaction point. [...]
