| Measurement of the top quark mass from single-top production events | ||

| Abstract: We measure the mass of the top quark from events where a single top quark is produced. The analysis is performed on data from pp collisions collected by the CMS detector at a center of mass energy of 8 TeV. The top quark is reconstructed from its decay $\mathrm{t} \rightarrow \mathrm{W}^+ \mathrm{b}$, with the $\mathrm{W}$ boson decaying leptonically in the muon channel. Specific event topology and kinematic properties are used in order to enrich the sample in single-top-quark events in the $t$-channel, at the expense of top-quark pair production events. For the single-top quark component, a fit to the reconstructed top invariant mass distribution yields $m_{\mathrm{t}} =$ 172.60 $\pm$ 0.77 (stat) $^{+0.97}_{-0.93}$ (syst) GeV. | ||
