Top-quark mass measurements: Alternative techniques (LHC + Tevatron)

Abstract. Measurements of the top-quark mass employing alternative techniques are presented, performed by the D0 and CDF collaborations at the Tevatron as well as the ATLAS and CMS experiments at the LHC. The alternative methods presented include measurements using the lifetime of B-hadrons, the transverse momentum of charged leptons and the endpoints of kinematic distributions in top quark anti-quark pair (tt̄) final states. The extraction of the top-quark pole mass from the tt ̄ production cross-section and the normalized differential tt̄ + 1-jet cross-section are discussed as well as the top-quark mass extraction using fixed-order QCD predictions at detector level. Finally, a measurement of the top-quark mass using events enhanced in single top t-channel production is presented. 1
