Measurement of the top quark mass in the dilepton channel using m[subscript T2] at CDF
We present measurements of the top quark mass using m[subscript T2], a variable related to the transverse mass in events with two missing particles. We use the template method applied to tt̅ dilepton events produced in pp̅ collisions at Fermilab’s Tevatron Collider and collected by the CDF detecto...

| description | We present measurements of the top quark mass using m[subscript T2], a variable related to the transverse mass in events with two missing particles. We use the template method applied to tt̅ dilepton events produced in pp̅ collisions at Fermilab’s Tevatron Collider and collected by the CDF detector. From a data sample corresponding to an integrated luminosity of 3.4 fb[superscript -1], we select 236 tt̅ candidate events. Using the m[subscript T2] distribution, we measure the top quark mass to be M[subscript top]=168.0[subscript -4.0][superscript +4.8](stat)±2.9(syst) GeV/c[superscript 2]. By combining m[subscript T2] with the reconstructed top quark mass distributions based on a neutrino weighting method, we measure M[subscript top]=169.3±2.7(stat)±3.2(syst) GeV/c[superscript 2]. This is the first application of the m[subscript T2] variable in a mass measurement at a hadron collider. |
