Measurement of prompt ψ (2S) to J /ψ yield ratios in Pb-Pb and p - p collisions at sNN =2.76 TeV
(American Physical Society, 2014-12-31)
The ratio between the prompt ψ(2S) and J/ψ yields, reconstructed via their decays into μ+μ−, is measured in Pb-Pb and p-p collisions at sNN−−−−√=2.76 TeV. The analysis is based on Pb-Pb and p-p data samples collected by ...
Search for dark matter and supersymmetry with a compressed mass spectrum in the vector boson fusion topology in proton-proton collisions at root s=8 TeV
(APS, 2017)
A first search for pair production of dark matter candidates through vector boson fusion in proton-proton collisions at √s=8 TeV is performed with the CMS detector. The vector boson fusion topology enhances missing ...
Measurement of the tt production cross section in pp collisions at √s=8 TeV in dilepton final states containing one τ lepton
(Elsevier, 2014-12-12)
The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying τ lepton from the process View the MathML source, where ℓ=e,μ. The data sample corresponds ...
Measurements of differential cross sections for associated production of a W boson and jets in proton-proton collisions at root s=8 TeV
(APS, 2017)
Differential cross sections for a W boson produced in association with jets are measured in a data sample of proton-proton collisions at a center-of-mass energy of 8 TeV recorded with the CMS detector and corresponding to ...
Observation of the decay B+ -> psi(2S)phi(1020)K+ in pp collisions at root s=8 TeV
(Elsevier, 2017)
The decay B+→ψ(2S)ϕ(1020)K+ is observed for the first time using data collected from pp collisions at View the MathML source by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6View the MathML ...
Search for anomalous Wtb couplings and flavour-changing neutral currents in t-channel single top quark production in pp collisions at root s=7 and 8 TeV
(Springer International, 2017)
Single top quark events produced in the t channel are used to set limits on anomalous Wtb couplings and to search for top quark flavour-changing neutral current (FCNC) interactions. The data taken with the CMS detector at ...
The CMS trigger system
(IOP , 2017)
This paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of potential physics interest from a GHz (MHz) interaction rate ...
Search for CP violation in t(t)over-bar production and decay in proton-proton collisions at root s=8 TeV
(Springer International, 2017)
The results of a first search for CP violation in the production and decay of top quark-antiquark ( tt¯tt¯ ) pairs are presented. The search is based on asymmetries in T-odd, triple-product correlation observables, where ...
Evidence for collectivity in pp collisions at the LHC
(Elsevier, 2017)
Measurements of two- and multi-particle angular correlations in pp collisions at View the MathML source are presented as a function of charged-particle multiplicity. The data, corresponding to integrated luminosities of ...
Measurement of differential cross sections for Higgs boson production in the diphoton decay channel in pp collisions at √s = 8 TeV
(Springer International Publishing, 2016-01)
A measurement is presented of differential cross sections for Higgs boson (H) production in pp collisions at s√=8s=8 TeVTeV . The analysis exploits the H→γγH→γγ decay in data corresponding to an integrated luminosity ...
