First evidence of double-parton scattering in same-sign WW production at CMS
The search for the same-sign WW production via double-parton scattering is presented, based on study of proton-proton collision data collected at $\sqrt{s}$ = 13TeV, using dimuon and electron-muon final states with the CMS experiment.

| Sumario: | The search for the same-sign WW production via double-parton scattering is presented, based on study of proton-proton collision data collected at $\sqrt{s}$ = 13TeV, using dimuon and electron-muon final states with the CMS experiment. First evidence for WW production via double-parton scattering, with a significance of 3.9 standard deviations, is presented. The measured inclusive crosssection is 1.41 ± 0.28 (stat)±0.28 (syst) pb. |
