Measurement of single top-quark production in association with a Formula Presented boson in Formula Presented collisions at Formula Presented with the ATLAS detector

Popis výsledku v původním jazyce

The inclusive cross section for the production of a single top quark in association with a ???? boson is measured using 140 fb^-1 of proton-proton collision data collected with the ATLAS detector at root ???? =13 TeV. Events containing two charged leptons and at least one jet identified as originating from a ????-quark are selected. A multivariate discriminant is constructed to separate the ????⁢???? signal from the ????⁢???? background. The cross section is extracted using a profile likelihood fit to the signal and control regions and it is measured to be ????????⁢???? =7⁢5+15^-14 pb, in good agreement with the Standard Model prediction. The measured cross section is used to extract a value for the left-handed form factor at the ????⁢????⁢???? vertex times the Cabibbo-Kobayashi-Maskawa matrix element |????_LV⁡|????_????⁢????| of 0.97 ±0.10.
