Constraints on the double-parton scattering cross section from same-sign W boson pair production in proton-proton collisions at √s = 8 TeV
(Springer International Publishing AG, 2018-02)
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 ...
Measurement of the inclusive t[bar over t] cross section in pp collisions at √s = 5.02 TeV using final states with at least one charged lepton
(Springer Berlin Heidelberg, 2018-03)
The top quark pair production cross section (σ[subscript t[bar over t]]) is measured for the first time in pp collisions at a center-of-mass energy of 5.02 TeV. The data were collected by the CMS experiment at the LHC and ...
Search for a heavy vector boson decaying to two gluons in pp̅ collisions at √s=1.96 TeV
(American Physical Society, 2012-12)
We present a search for a new heavy vector boson Z[superscript ′] that decays to gluons. Decays to on-shell gluons are suppressed, leading to a dominant decay mode of Z[superscript ′]→g[superscript *]g. We study the case ...
Measurement of the B[subscript c][superscript -] meson lifetime in the decay B[subscript c][superscript -] →J/ψπ[superscript -]
(American Physical Society, 2013-01)
The lifetime of the B[subscript c][superscript -] meson is measured using 272 exclusive B[subscript c][superscript -]→J/ψ(→μ[superscript +]μ[superscript -])π[superscript -] decays reconstructed in data from proton-antiproton ...
Combination of the top-quark mass measurements from the Tevatron collider
(American Physical Society, 2012-11)
The top quark is the heaviest known elementary particle, with a mass about 40 times larger than the mass of its isospin partner, the bottom quark. It decays almost 100% of the time to a W boson and a bottom quark. Using ...
Search for supersymmetry in events with one lepton and multiple jets in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2017-01)
A search for supersymmetry is performed in events with a single electron or muon in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC and correspond to ...
Study of the underlying event at forward rapidity in pp collisions at √s=0.9,2.76, and 7 TeV
(Springer Science and Business Media LLC, 2013)
© 2013, CERN. The underlying event activity in proton-proton collisions at forward pseudo-rapidity (—6.6 < η < —5.2) is studied with the CMS detector at the LHC, using a novel observable: the ratio of the forward energy ...
Search for flavor changing neutral currents in top quark decays in pp collisions at 7 TeV
(Elsevier BV, 2013)
The results of a search for flavor changing neutral currents in top quark decays t→Zq in events with a topology compatible with the decay chain tt̄→Wb+Zq→ℓνb+ℓℓq are presented. The search is performed with a data sample ...
Search for top squark pair production in compressed-mass-spectrum scenarios in proton–proton collisions at √s = 8 TeV using the αT variable
(Elsevier BV, 2017)
© 2017 The Author An inclusive search is performed for supersymmetry in final states containing jets and an apparent imbalance in transverse momentum, p→Tmiss, due to the production of unobserved weakly interacting particles ...
Performance of τ-lepton reconstruction and identification in CMS
(IOP Publishing, 2012-01-01)
The performance of τ-lepton reconstruction and identification algorithms is studied using a data sample of proton-proton collisions at s = 7 TeV, corresponding to an integrated luminosity of 36 pb-1 collected with the CMS ...
