Searches for supersymmetry based on events with b jets and four W bosons in pp collisions at 8 TeV
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 ...
Long-range two-particle correlations of strange hadrons with charged particles in pPb and PbPb collisions at LHC energies
Measurements of two-particle angular correlations between an identified strange hadron (K0 S or Λ/Λ) and a charged particle, emitted in pPb collisions, are presented over a wide range in pseudorapidity and full azimuth. ...
Angular coefficients of Z bosons produced in pp collisions at √s=8 TeV and decaying to μ+μ- as a function of transverse momentum and rapidity
Measurements of the five most significant angular coefficients, A0 through A4, for Z bosons produced in pp collisions at √s=8 TeV and decaying to μ+μ- are presented as a function of the transverse momentum and rapidity of ...
Measurement of the W boson helicity in events with a single reconstructed top quark in pp collisions at √s = 8 TeV
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 ...
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 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 ...
