We determine the top quark mass m_t using t-tbar pairs produced in the D0 detector by \sqrt{s} = 1.8 TeV p-pbar collisions in a 125 pb^-1 exposure at the Fermilab Tevatron. We make a two constraint fit to m_t in t-tbar -> b W^+bbar W^-…

We present a measurement of the top quark mass using 19.7 $\pm$ 0.5 fb$^{-1}$ of $\sqrt{s} = 8$ TeV CMS data. In particular, we study dileptonic $t\bar{t}$ decays, in which a top-antitop pair decays to a final state containing two electrons…
