| Özet |
| The first observation of the associated production of a single top quark and a boson is presented. The analysis is based on a data set corresponding to an integrated luminosity of of proton-proton collisions at recorded by the CMS experiment at the LHC. Events with two leptons and a jet originating from a quark are selected. A multivariate analysis based on kinematic and topological properties is used to separate the signal from the dominant background. An excess consistent with the signal hypothesis is observed, with a significance which corresponds to 6.1 standard deviations above a background-only hypothesis. The measured production cross section is , in agreement with the standard model prediction. |
