SEMINARIUM FIZYKI WIELKICH ENERGII

Dnia 15 listopada (piątek) o godzinie 11:30, w sali B2.38 odbędzie się seminarium, na którym zostanie wygłoszony referat pt.:

„CMS measurement of the W boson mass in proton-proton collisions at √s =13 TeV”

Referuje: prof. dr hab. Krzysztof Doroba (IFD UW)

Precision tests of Standard Model (SM) are very important part of LHC scientific program. Since Higgs discovery and determination of its mass by ATLAS and CMS all the parameters of electroweak (EW) sector of the SM are now constrained by experimental measurements. Established disagreement between W boson mass measurement and SM prediction could be a tip towards physics beyond the SM (BSM). In the seminar the recent W boson mass measurement by Compact Muon Collaboration will be presented (m_W=80 360.2±9.6 MeV) with the special emphasis on its accuracy and the way to achieve it.
