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 of ϒ(1S), ϒ(2S), and ϒ(3S) quarkonium states in PbPb collisions at sNN=2.76TeV
(2017-07-10)
The production yields of ϒ(1S), ϒ(2S), and ϒ(3S) quarkonium states are measured through their decays into muon pairs in the CMS detector, in PbPb and pp collisions at the centre-of-mass energy per nucleon pair of 2.76 TeV. ...
Suppression and azimuthal anisotropy of prompt and nonprompt J / ψ production in PbPb collisions at √sNN=2.76TeV
