Additional information

This publication reports on an algorithm (JetProb) which identifies jets coming from bottom quarks. I contributed to the

optimisation criteria for the electron selection. I also developed, together with three PhD students and a PDRA under my

supervision and collaborators, an alternative algorithm that identifies b-jets based on the presence of a muon. This algorithm has a smaller systematic uncertainty than lifetime-based ones (e.g., JetProb) and was also used for measuring the top anti-top quark cross-section at 7 TeV. Results using this algorithm have been shown at conferences since August 2012 and is currently being used in various ATLAS analyses.
