| Özet |
| The first evidence of events consistent with the production of a single top quark in association with a photon is reported. The analysis is based on proton-proton collisions at and recorded by the CMS experiment in 2016, corresponding to an integrated luminosity of . Events are selected by requiring the presence of a muon (), a photon (), an imbalance in transverse momentum from an undetected neutrino (), and at least two jets () of which exactly one is identified as associated with the hadronization of a quark. A multivariate discriminant based on topological and kinematic event properties is employed to separate signal from background processes. An excess above the background-only hypothesis is observed, with a significance of 4.4 standard deviations. A fiducial cross section is measured for isolated photons with transverse momentum greater than 25 GeV in the central region of the … |
