| Özet |
| A measurement of the top quark mass () in the dileptonic decay channel is performed using data from proton-proton collisions at a center-of-mass energy of 8 TeV. The data was recorded by the CMS experiment at the LHC and corresponds to an integrated luminosity of . Events are selected with two oppositely charged leptons (, ) and two jets identified as originating from quarks. The analysis is based on three kinematic observables whose distributions are sensitive to the value of . An invariant mass observable, , and a “stransverse mass” observable, , are employed in a simultaneous fit to determine the value of and an overall jet energy scale factor (JSF). A complementary approach is used to construct an invariant mass observable, , that is combined with to measure . The shapes of the observables, along with their evolutions in and JSF, are modeled by a nonparametric … |
