Measuring the Top Quark Mass using Kinematic Endpoints
We report on a simultaneous measurement of the top quark, W boson, and neutrino masses in $t\bar{t}$ dilepton decays with $4.98 \mathrm{fb}^{-1}$ of data from the CMS experiment. The analysis is based on endpoint determinations in kinematic distributions. In addition to the unconstrained fit for thr...

| description | We report on a simultaneous measurement of the top quark, W boson, and neutrino masses in $t\bar{t}$ dilepton decays with $4.98 \mathrm{fb}^{-1}$ of data from the CMS experiment. The analysis is based on endpoint determinations in kinematic distributions. In addition to the unconstrained fit for three masses, the neutrino and W boson masses can be constrained to standard values; in the maximally constrained fit, the top quark mass is found to be $M_t = 173.9 \pm 0.9 (stat) {}^{+1.2}_{-1.8} (syst) $ GeV. |
