Search for lepton-flavour-violating decays of the Higgs boson
The first direct search for lepton-flavour-violating decays of the recently discovered Higgs boson (H) is described. The search is performed in the H → μτe and H → μτh channels, where τe and τh are tau leptons reconstructed ...
Searches for supersymmetry using the MT2 variable in hadronic events produced in pp collisions at 8 TeV
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 T2 variable, which is a measure of the transverse momentum ...
Search for W′→tb decays in the lepton + jets final state in pp collisions at √s = 8 TeV
Results are presented from a search for the production of a heavy gauge boson W′ decaying into a top and a bottom quark, using a data set collected by the CMS experiment at √s = 8 TeV and corresponding to an integrated ...
Search for disappearing tracks in proton-proton collisions at √s = 8 TeV
A search is presented for long-lived charged particles that decay within the CMS detector and produce the signature of a disappearing track. Disappearing tracks are identified as those with little or no associated calorimeter ...
Study of Z production in PbPb and pp collisions at √sNN = 2.76 TeV in the dimuon and dielectron decay channels
The production of Z bosons is studied in the dimuon and dielectron decay channels in PbPb and pp collisions at √sNN = 2.76 TeV, using data collected by the CMS experiment at the LHC. The PbPb data sample corresponds to ...
Measurement of the ratio of the production cross sections times branching fractions of B± c → J / ψπ± and B± → J / ψK± and B (B± c → J / ψπ±π ±π ∓) / B (B± c → J / ψπ±) in pp collisions at √s = 7 TeV
Abstract: The ratio of the production cross sections times branching fractions σ(B± c )B(B± c → J/ψπ±) / σ(B±)B(B± → J/ψK±) is studied in proton-proton collisions at a center-of-mass energy of 7 TeV with ...

Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s = 8 TeV
A search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at √s = 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 fb−1 ...
Search for physics beyond the standard model in events with two leptons, jets, and missing transverse momentum in pp collisions at √s = 8 TeV
A search is presented for physics beyond the standard model in final states with two opposite-sign same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity of 19.4 ...
Measurement of prompt J/ψ pair production in pp collisions at √s = 7 Tev
Production of prompt J/ψ meson pairs in proton-proton collisions at √s = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb−1. The two J/ψ ...
