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 the tt production cross section using events in the eμ final state in pp collisions at √s = 13 TeV
(Springer Nature, 2017-03)
© 2017, CERN for the benefit of the CMS collaboration. The cross section of top quark–antiquark pair production in proton–proton collisions at s=13TeV is measured by the CMS experiment at the LHC, using data corresponding ...
Measurement of the Transverse Momentum Spectra of Weak Vector Bosons Produced in Proton-Proton Collisions at √s = 8 TeV
(Springer Berlin Heidelberg, 2017-02)
The transverse momentum spectra of weak vector bosons are measured in the CMS experiment at the LHC. The measurement uses a sample of proton-proton collisions at s=8 TeV, collected during a special low-luminosity running ...
Measurements of differential cross sections for associated production of a W boson and jets in proton-proton collisions at √s=8 TeV
(American Physical Society (APS), 2017-03)
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 ...
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 ...
Search for microscopic black holes in pp collisions at √s=8 TeV
(Springer Berlin Heidelberg, 2013-07)
A search for microscopic black holes and string balls is presented, based on a data sample of pp collisions at √s=8 TeV recorded by the CMS experiment at the Large Hadron Collider and corresponding to an integrated ...
Measurement of differential top-quark-pair production cross sections in pp collisions at √s = 7TeV
Search for heavy quarks decaying into a top quark and a W or Z boson using lepton + jets events in pp collisions at s√=7TeV
Results are presented from a search for the pair-production of heavy quarks, QQ[overline appears over second Q], that decay exclusively into a top quark and a W or Z boson. The search is performed using a sample of ...
Search for new long-lived particles at √s = 13 TeV
A search for long-lived particles was performed with data corresponding to an integrated luminosity of 2.6 fb⁻¹ collected at a center-of-mass energy of 13 TeV by the CMS experiment in 2015. The analysis exploits two ...
Search for top squarks and dark matter particles in opposite-charge dilepton final states at √s = 13 TeV
(American Physical Society, 2018-02)
A search for new physics is presented in final states with two oppositely charged leptons (electrons or muons), jets identified as originating from b quarks, and missing transverse momentum (p[subscript T][superscript ...
