Abstract

We report on a simultaneous measurement of the top quark, W boson, and neutrino masses in ttˉt\bar{t} dilepton decays with 4.98fb14.98 \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 Mt=173.9±0.9(stat)1.8+1.2(syst)M_t = 173.9 \pm 0.9 (stat) {}^{+1.2}_{-1.8} (syst) GeV.
