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 ...
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 ...
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 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 ...
Search for long-lived particles that decay into final states containing two electrons or two muons in proton-proton collisions at s =8TeV
A search is performed for long-lived particles that decay into final states that include a pair of electrons or a pair of muons. The experimental signature is a distinctive topology consisting of a pair of charged leptons ...
Search for resonant pair production of Higgs bosons decaying to two bottom quark-antiquark pairs in proton-proton collisions at 8 TeV
A model-independent search for a narrow resonance produced in proton-proton collisions at √s=8 TeV and decaying to a pair of 125 GeV Higgs bosons that in turn each decays into a bottom quark-antiquark pair is performed by ...
