Search for long-lived neutral particles decaying to quark-antiquark pairs in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2015-01)
A search is performed for long-lived massive neutral particles decaying to quark-antiquark pairs. The experimental signature is a distinctive topology of a pair of jets, originating at a secondary vertex. Events were ...
Search for Displaced Supersymmetry in Events with an Electron and a Muon with Large Impact Parameters
(American Physical Society, 2015-02)
A search for new long-lived particles decaying to leptons is presented using proton-proton collisions produced by the LHC at √s = 8 TeV. Data used for the analysis were collected by the CMS detector and correspond to an ...
Study of final-state radiation in decays of Z bosons produced in pp collisions at 7 TeV
(American Physical Society, 2015-05)
The differential cross sections for the production of photons in Z → μ[superscript +]μ[superscript −]γ decays are presented as a function of the transverse energy of the photon and its separation from the nearest muon. The ...
Long-range two-particle correlations of strange hadrons with charged particles in pPb and PbPb collisions at LHC energies
(Elsevier, 2015-01)
Measurements of two-particle angular correlations between an identified strange hadron (K[0 over S] or [Λ over [bar over Λ]]) and a charged particle, emitted in pPb collisions, are presented over a wide range in pseudorapidity ...
Search for standard model production of four top quarks in the lepton + jets channel in pp collisions at √s = 8 TeV
(Springer-Verlag Berlin Heidelberg, 2014-11)
A search is presented for standard model (SM) production of four top quarks (tt¯tt¯) in pp collisions in the lepton + jets channel. The data correspond to an integrated luminosity of 19.6 fb[superscript −1] recorded at a ...
Searches for supersymmetry using the M[subscript T2] variable in hadronic events produced in pp collisions at 8 TeV
(Springer-Verlag, 2015-05)
Searches for supersymmetry (SUSY) are performed using a sample of hadronic events produced in 8 TeV pp collisions at the CERN LHC. The searches are based on the M[subscript T2] variable, which is a measure of the transverse ...
Search for new physics in events with opposite-sign leptons, jets, and missing transverse energy in pp collisions at √s = 7 TeV
(Elsevier, 2012-11)
A search is presented for physics beyond the standard model (BSM) in final states with a pair of opposite-sign isolated leptons accompanied by jets and missing transverse energy. The search uses LHC data recorded at a ...
Evidence for the 125 GeV Higgs boson decaying to a pair of τ leptons
(Springer-Verlag, 2014-05)
A search for a standard model Higgs boson decaying into a pair of τ leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012. The dataset corresponds to an integrated luminosity of 4.9 ...
Searches for supersymmetry based on events with b jets and four W bosons in pp collisions at 8 TeV
(Elsevier, 2015-04)
Five mutually exclusive searches for supersymmetry are presented based on events in which b jets and four W bosons are produced in proton–proton collisions at √s = 8 TeV. The data, corresponding to an integrated luminosity ...
Measurement of top quark–antiquark pair production in association with a W or Z boson in pp collisions at √s = 8 TeV
(Springer-Verlag, 2014-09)
A measurement of the cross section for the production of top quark–antiquark pairs ( t [bar over t]) in association with a vector boson V (W or Z) in proton-proton collisions at √s=8 TeV is presented. The results are based ...
