Search for third-generation scalar leptoquarks and heavy right-handed neutrinos in final states with two tau leptons and two jets in proton-proton collisions at √s=13 TeV
(2017-07-26)
A search is performed for third-generation scalar leptoquarks and heavy right-handed neutrinos in events containing one electron or muon, one hadronically decaying τ lepton, and at least two jets, using a s=13 TeV pp ...
Search for massive resonances decaying into WW, WZ or ZZ bosons in proton-proton collisions at √s=13 TeV
(2017-03-30)
A search is presented for new massive resonances decaying to WW, WZ or ZZ bosons in ℓνqq¯ and qq¯ qq¯ final states. Results are based on data corresponding to an integrated luminosity of 2.3-2.7 fb−1 recorded in proton-proton ...
Suppression and azimuthal anisotropy of prompt and nonprompt J / ψ production in PbPb collisions at √sNN=2.76TeV
(2017-04-19)
The nuclear modification factor RAA and the azimuthal anisotropy coefficient v2 of prompt and nonprompt (i.e. those from decays of b hadrons) J / ψ mesons, measured from PbPb and pp collisions at sNN=2.76TeV at the LHC, ...
Search for physics beyond the standard model in events with two leptons of same sign, missing transverse momentum, and jets in proton–proton collisions at √s=13TeV
(2017-09-01)
A data sample of events from proton–proton collisions with two isolated same-sign leptons, missing transverse momentum, and jets is studied in a search for signatures of new physics phenomena by the CMS Collaboration at ...
Measurement of the production cross section of a W boson in association with two b jets in pp collisions at √s=8TeV
(2017-02-11)
