Search for supersymmetry with photons in pp collisions at √s = 8 TeV
(American Physical Society, 2015-10)
Two searches for physics beyond the standard model in events containing photons are presented. The data sample used corresponds to an integrated luminosity of 19.7 fb[superscript −1] of proton-proton collisions at √s = ...
Search for a heavy gauge boson W' in the final state with an electron and large missing transverse energy in pp collisions at √s = 7 TeV
(Elsevier, 2011-02)
A search for a heavy gauge boson W′ has been conducted by the CMS experiment at the LHC in the decay channel with an electron and large transverse energy imbalance E[miss over T], using proton–proton collision data ...
Study of hadronic event-shape variables in multijet final states in pp collisions at √s = 7 TeV
(Springer-Verlag/International School for Advanced Studies (SISSA), 2014-10)
Event-shape variables, which are sensitive to perturbative and nonperturbative aspects of quantum chromodynamic (QCD) interactions, are studied in multijet events recorded in proton-proton collisions at √s = 7 TeV. Events ...
Search for Dark Matter Produced with an Energetic Jet or a Hadronically Decaying W or Z Boson at √s = 13 TeV
(Springer Berlin Heidelberg, 2017-07)
A search for dark matter particles is performed using events with large missing transverse momentum, at least one energetic jet, and no leptons, in proton-proton collisions at √s = 13 TeV collected with the CMS detector ...
Measurement of the W boson helicity in events with a single reconstructed top quark in pp collisions at √s = 8 TeV
(Springer-Verlag, 2015-01)
A measurement of the W boson helicity is presented, where the W boson originates from the decay of a top quark produced in pp collisions. The event selection, optimized for reconstructing a single top quark in the final ...
Searches for Invisible Decays of the Higgs Boson in pp Collisions at √s = 7, 8, and 13 TeV
(Springer Nature, 2017-02)
Searches for invisible decays of the Higgs boson are presented. The data collected with the CMS detector at the LHC correspond to integrated luminosities of 5.1, 19.7, and 2.3 fb⁻¹ at centre-of-mass energies of 7, 8, and ...
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 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 ...
