Searches for long-lived charged particles in pp collisions at √s = 7 and 8 TeV
(2013-07-19)
Results of searches for heavy stable charged particles produced in pp collisions at √s = 7 and 8 TeV are presented corresponding to an integrated luminosity of 5.0 fb−1 and 18.8 fb−1, respectively. Data collected with ...
Constraints on the double-parton scattering cross section from same-sign W boson pair production in proton-proton collisions at √s=8 TeV
(2018-02-01)
A first search for same-sign WW production via double-parton scattering is performed based on proton-proton collision data at a center-of-mass energy of 8 TeV using dimuon and electron-muon final states. The search is based ...
Study of double parton scattering using W + 2-jet events in proton-proton collisions at √s = 7 TeV
(2014-03-05)
Double parton scattering is investigated in proton-proton collisions at s√ = 7 TeV where the final state includes a W boson, which decays into a muon and a neutrino, and two jets. The data sample corresponds to an integrated ...
Measurement of the Λb polarization and angular parameters in Λb → J=ψΛ decays from pp collisions at ffiffi s p = 7 and 8 TeV
(2018-04-17)
An analysis of the bottom baryon decay Λb→J/ψ(→μ+μ-)Λ(→pπ-) is performed to measure the Λb polarization and three angular parameters in data from pp collisions at s=7 and 8 TeV, collected by the CMS experiment at the Large ...
Search for resonant t̄t production in lepton+jets events in pp collisions at √s = 7 TeV
(2012-12-04)
A model-independent search for the production of heavy resonances decaying into top-antitop quark pairs is presented. The search is based on events containing one lepton (muon or electron) and at least two jets selected ...
Observation of Top Quark Production in Proton-Nucleus Collisions
(2017-12-14)
The first observation of top quark production in proton-nucleus collisions is reported using proton-lead data collected by the CMS experiment at the CERN LHC at a nucleon-nucleon center-of-mass energy of sNN=8.16 TeV. The ...
Measurement of the production cross sections for a Z boson and one or more b jets in pp collisions at √s = 7 TeV
(2014-06-12)
The production of a Z boson, decaying into two leptons and produced in association with one or more b jets, is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV. The data were ...
Principal-component analysis of two-particle azimuthal correlations in PbPb and pPb collisions at CMS
(2017-12-05)
For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from sNN=2.76TeV PbPb and ...
