Observation of the associated production of a single top quark and a W boson in pp collisions at sqrt(s) = 8 TeV

CMS Collaboration

Understand

The first observation of the associated production of a single top quark and a W boson is presented.

The analysis is based on a data set corresponding to an integrated luminosity of 12.2 inverse femtobarns of proton-proton collisions at sqrt(s) = 8 TeV recorded by the CMS experiment at the LHC.
Events with two leptons and a jet originating from a b quark are selected.
A multivariate analysis based on kinematic and topological properties is used to separate the signal from the dominant t t-bar background.
