TY - T1 - Top Quark Mass Measurement in the lepton+jets Channel Using a Matrix Element Method and in situ Jet Energy Calibration SN - / UR - http://hdl.handle.net/10138/24393 T3 - A1 - Aaltonen, Timo; Brücken, Erik; Devoto, Francesco; Mehtälä, Petteri; Orava, Risto; CDF Collaboration A2 - PB - Y1 - 2010 LA - eng AB - A precision measurement of the top quark mass m_t is obtained using a sample of ttbar events from ppbar collisions at the Fermilab Tevatron with the CDF II detector. Selected events require an electron or muon, large missing transverse energy, and exactly four high-energy jets, at least one of which is tagged as coming from a b quark. A likelihood is calculated using a matrix element method with quasi-Monte Carlo integration taking into account finite detector resolution and jet mass effects. Th...
