Description
A measurement of the top quark mass is reported in events containing a
single top quark produced via the electroweak t channel. The analysis is
performed using data from proton-proton collisions collected with the
CMS detector at the LHC at a centre-of-mass energy of 8 TeV,
corresponding to an integrated luminosity of 19.7 fb^{-1}. Top quark
candidates are reconstructed from their decay to a W boson and a b
quark, with the W boson decaying leptonically to a muon and a neutrino.
The final state signature and kinematic properties of single top quark
events in the t channel are used to enhance the purity of the sample,
suppressing the contribution from top quark pair production. A fit to
the invariant mass distribution of reconstructed top quark candidates
yields a value of the top quark mass of 172.95 ± 0.77 {(stat)}
^{+0.97}_{-0.93} {(syst)} {GeV} . This result is in agreement with the
current world average, and represents the first measurement of the top
quark mass in event topologies not dominated by top quark pair
production, therefore contributing to future averages with partially
uncorrelated systematic uncertainties and a largely uncorrelated
statistical uncertainty.
