Precision Measurement of the Mass of the Top Quark in p $$\bar{p}$$ Collisions
- Univ. of Rochester, NY (United States)
We report a measurement of the mass of the top quark (mtop) in p$$\bar{p}$$ collisions at a center of mass energy of 1.96 TeV. The analysis is based on p$$\bar{p}$$→t$$\bar{t}$$→ lepton+jets data recorded with the D0 detector at the Fermilab Tevatron Collider. Events were preselected in the e+jets (913 events/pb of data) and in the μ+jets (871 events/pb of data) channels. These were analyzed through a comparison of the matrix element for the production and decay of the t$$\bar{t}$$ states with data, using a likelihood method and 'tagged' b quarks from the t → Wb decays.
