Top quark mass measurement in the eμ channel using the mT2 variable at ATLAS

A measurement of the top-quark mass using the mT2 stransverse mass variable in the emu channel in \sqrt{s} = 7 TeV pp collision data taken in 2011 at the LHC is presented. The mT2 variable is useful in pair-production events with two undetected particles and represents a lower bound on the parent pa...

description A measurement of the top-quark mass using the mT2 stransverse mass variable in the emu channel in \sqrt{s} = 7 TeV pp collision data taken in 2011 at the LHC is presented. The mT2 variable is useful in pair-production events with two undetected particles and represents a lower bound on the parent particle's mass. Applying this method to 4.7/fb of ATLAS data, a measurement of the top-quark mass is made, resulting in m(top)= 175.2 +- 1.6 (stat.) +3.1-2.8(syst.)GeV.
