A search for pair production of new light bosons decaying into muons in proton-proton collisions at 13 TeV / А. М. Sirunyan, A. R. Tumasyan, W. Adam [et al.]
Уровень набора: Physics Letters BЯзык: английский.Резюме или реферат: A search for new light bosons decaying into muon pairs is presented using a data sample corresponding to an integrated luminosity of 35.9 of proton-proton collisions at a center-of-mass energy , collected with the CMS detector at the CERN LHC. The search is model independent, only requiring the pair production of a new light boson and its subsequent decay to a pair of muons. No significant deviation from the predicted background is observed. A model independent limit is set on the product of the production cross section times branching fraction to dimuons squared times acceptance as a function of new light boson mass.

It is then interpreted in the context of the next-to-minimal supersymmetric standard model and a dark supersymmetry model that allows for nonnegligible light boson lifetimes. In both cases, there is significant improvement over previously published limits..Примечания о наличии в документе библиографии/указателя: [References.: 86 tit.].Тематика: электронный ресурс | труды учёных ТПУ | CMS | new light boson | supersymmetry | hidden sector | dark photon | muon | бозоны | фотоны | суперсимметрии Ресурсы он-лайн:Щелкните здесь для доступа в онлайнTitle screen
