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 ...

Comparison of the Z/γ ∗ + jets to γ + jets cross sections in pp collisions at √s = 8 TeV
A comparison of the differential cross sections for the processes Z/γ * + jets and photon (γ)+jets is presented. The measurements are based on data collected with the CMS detector at √s = 8 TeV corresponding to an integrated ...
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 the underlying event activity using charged-particle jets in proton-proton collisions at √s = 2.76 TeV
A measurement of the underlying event (UE) activity in proton-proton collisions is performed using events with charged-particle jets produced in the central pseudorapidity region (|η jet| < 2) and with transverse momentum ...
Measurement of the cross section ratio σttbb/σttjj in pp collisions at √s=8 TeV
The first measurement of the cross section ratio σttbb/σttjj is presented using a data sample corresponding to an integrated luminosity of 19.6 fb−1 collected in pp collisions at √s = 8 TeV with the CMS detector at the ...
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 ...
Search for neutral MSSM Higgs bosons decaying into a pair of bottom quarks
A search for neutral Higgs bosons decaying into a bb¯ quark pair and produced in association with at least one additional b quark is presented. This signature is sensitive to the Higgs sector of the minimal supersymmetric ...
Study of W boson production in pPb collisions at √sNN=5.02TeV
The first study of W boson production in pPb collisions is presented, for bosons decaying to a muon or electron, and a neutrino. The measurements are based on a data sample corresponding to an integrated luminosity of ...
