Evidence for associated production of a single top quark and W boson in pp collisions at sqrt(s) = 7 TeV

Understand

Evidence is presented for the associated production of a single top quark and W boson in pp collisions at sqrt(s) = 7 TeV with the CMS experiment at the LHC.

• The analyzed data corresponds to an integrated luminosity of 4.9 inverse femtobarns.
• The measurement is performed using events with two leptons and a jet originated from a b quark.
• A multivariate analysis based on kinematic properties is utilized to separate the t t-bar background from the signal.
