Search for a Higgs boson decaying into a Z and a photon in pp collisions at √ s = 7 and 8 TeV
(Elsevier BV, 2013)
A search for a Higgs boson decaying into a Z boson and a photon is described. The analysis is performed using proton-proton collision datasets recorded by the CMS detector at the LHC. Events were collected at center-of-mass ...
Search for supersymmetry in events with a lepton, a photon, and large missing transverse energy in pp collisions at √ s = 7 TeV
(Springer Science and Business Media LLC, 2011)
A search is performed for an excess of events, over the standard model expectations, with a photon, a lepton, and large missing transverse energy in pp collisions at s√ = 7TeV. Such events are expected in many new physics ...
Performance of the CMS missing transverse momentum reconstruction in pp data at √s = 8 TeV
(IOP Publishing, 2015-02)
The performance of missing transverse energy reconstruction algorithms is presented using √s = 8 TeV proton-proton (pp) data collected with the CMS detector. Events with anomalous missing transverse energy are studied, ...
Search for long-lived particles using nonprompt jets and missing transverse momentum with proton-proton collisions at √ s = 13 TeV
(Elsevier BV, 2019-08)
A search for long-lived particles decaying to displaced, nonprompt jets and missing transverse momentum is presented. The data sample corresponds to an integrated luminosity of 137 fb−1 of proton-proton collisions at a ...
Search for an L − L gauge boson using Z → 4μ events in proton-proton collisions at √ s = 13 TeV
(Elsevier BV, 2019-03)
A search for a narrow Z ′ gauge boson with a mass between 5 and 70 GeV resulting from an L μ −L τ U(1) local gauge symmetry is reported. Theories that predict such a particle have been proposed as an explanation of various ...
Measurement of differential cross sections for the production of top quark pairs and of additional jets in √s = 13 TeV
(American Physical Society, 2018-06)
Differential and double-differential cross sections for the production of top quark pairs in proton-proton collisions at √s = 13 TeV are measured as a function of kinematic variables of the top quarks and the top quark-antiquark ...
Search for new phenomena in final states with two opposite-charge, same-flavor leptons, jets, and missing transverse momentum in pp collisions at √s = 13 TeV
(Springer Berlin Heidelberg, 2018-03)
Search results are presented for physics beyond the standard model in final states with two opposite-charge, same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity ...
Measurements of t ̄t cross sections in association with b jets and inclusive jets and their ratio using dilepton final states in pp collisions at √s = 13 TeV
