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

\mathrm{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~\mathrm{(stat)}~^{+0.97}_{-0.93}~\mathrm{(syst)}

GeV.
