Search for lepton flavour violating decays of the Higgs boson to eτ and eμ in proton–proton collisions at s=8 TeV
(2016-12-10)
A direct search for lepton flavour violating decays of the Higgs boson (H) in the H→eτ and H→eμ channels is described. The data sample used in the search was collected in proton–proton collisions at s=8 TeV with the CMS ...
ϒ(nS) polarizations versus particle multiplicity in pp collisions at s=7 TeV
(2016-10-10)
The polarizations of the ϒ(1S), ϒ(2S), and ϒ(3S) mesons are measured as a function of the charged particle multiplicity in proton–proton collisions at s=7 TeV. The measurements are performed with a dimuon data sample ...
Study of Z boson production in pPb collisions at √sNN=5.02 TeV
(2016-08-10)
The production of Z bosons in pPb collisions at sNN=5.02 TeV is studied by the CMS experiment via the electron and muon decay channels. The inclusive cross section is compared to pp collision predictions, and found to scale ...
Inclusive search for supersymmetry using razor variables in pp collisions at s =13 TeV
(2017-01-06)
An inclusive search for supersymmetry using razor variables is performed in events with four or more jets and no more than one lepton. The results are based on a sample of proton-proton collisions corresponding to an ...
