| Özet |
| A search for production from double-parton scattering processes using same-charge electron-muon and dimuon events is reported, based on proton-proton collision data collected at a center-of-mass energy of . The analyzed data set corresponds to an integrated luminosity of , collected using the CMS detector at the LHC in 2016 and 2017. Multivariate classifiers are used to discriminate between the signal and the dominant background processes. A maximum likelihood fit is performed to extract the signal cross section. This leads to the first evidence for production via double-parton scattering, with a significance of 3.9 standard deviations. The measured inclusive cross section is . |
