Study of final-state radiation in decays of Z bosons produced in pp collisions at 7 TeV
The differential cross sections for the production of photons in Z→μ+μ-γ decays are presented as a function of the transverse energy of the photon and its separation from the nearest muon. The data for these measurements ...
Measurement of the production cross section ratio σ(χb2(1P))/σ(χb1(1P)) in pp collisions at s=8TeV
A measurement of the production cross section ratio σ(χb2(1P))/σ(χb1(1P)) is presented. The χb1(1P) and χb2(1P) bottomonium states, promptly produced in pp collisions at s=8TeV, are detected by the CMS experiment at the ...
Search for narrow high-mass resonances in proton-proton collisions at √s = 8 TeV decaying to a Z and a Higgs boson
A search for a narrow, high-mass resonance decaying into Z and Higgs (H) bosons is presented. The final state studied consists of a merged jet pair and a τ pair resulting from the decays of Z and H bosons, respectively. ...
Search for the production of dark matter in association with top-quark pairs in the single-lepton final state in proton-proton collisions at √s = 8 TeV
A search is presented for particle dark matter produced in association with a pair of top quarks in pp collisions at a centre-of-mass energy of √s = 8 TeV. The data were collected with the CMS detector at the LHC and ...
Search for vector-like T quarks decaying to top quarks and Higgs bosons in the all-hadronic channel using jet substructure
A search is performed for a vector-like heavy T quark that is produced in pairs and that decays to a top quark and a Higgs boson. The data analysed correspond to an integrated luminosity of 19.7 fb−1 collected with the CMS ...
