Results are presented from a search for physics beyond the standard model based on events with large missing transverse energy, at least three jets, and at least one, two, or three b-quark jets. The study is performed using ...

The production of b jets in association with a Z/γ*boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7TeV and recorded by the CMS detector. The inclusive cross section for ...

The results of a search for flavor changing neutral currents in top quark decays t→Zq in events with a topology compatible with the decay chain tt¯→Wb+Zq→ℓνb+ℓℓq are presented. The search is performed with a data sample ...

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 ...

Isolated photon production is measured in proton–proton and lead–lead collisions at nucleon–nucleon centre-of-mass energies of 2.76 TeV in the pseudorapidity range |η|<1.44 and transverse energies E[subscript T] between ...

Results are presented from a search for heavy, right-handed muon neutrinos, N[subscript μ], and right-handed WR bosons, which arise in the left-right symmetric extensions of the standard model. The analysis is based on a ...

Measurements of jet production rates in association with W and Z bosons for jet transverse momenta above 30 GeV are reported, using a sample of proton-proton collision events recorded by CMS at √s = 7 TeV, corresponding ...

A measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at √s = 7 TeV, pp → pμ⁺μ⁻ p, is reported using data corresponding to an integrated luminosity of 40 pb⁻¹. For muon pairs with ...
