Measurement of the top quark mass using single top quark events in proton-proton collisions at sqrt(s) = 8 TeV

Understand

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 inverse femtobarns.
• 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.
