Measurements are presented of the lifetimes of the B0, Bs0, Λb0, and Bc+ hadrons using the decay channels B0 → J/ψ K ∗(892) 0, B0 → J/ψ KS0, B s0 → J/ψ π+ π-, B s0 → J /ψ ϕ (1020), Λ b0 → J/ψ Λ0, and Bc+ → J/ψ π+. The ...

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 ...

A search for new exotic particles decaying to the VZ final state is performed, where V is either a W or a Z boson decaying into two overlapping jets and the Z decays into a pair of electrons, muons or neutrinos. The analysis ...

A search for lepton flavour violating decays of the Higgs boson in the μτ and eτ decay modes is presented. The search is based on a data set corresponding to an integrated luminosity of 35.9 fb⁻¹ of proton-proton collisions ...

The production of the X(3872) is studied in pp collisions at √s = 7 TeV, using decays to J/ψπ[superscript] + π[superscript −], where the J/ψ decays to two muons. The data were recorded by the CMS experiment and correspond ...

The tt¯ charge asymmetry is measured in proton–proton collisions at a centre-of-mass energy of 8 TeV. The data, collected with the CMS experiment at the LHC, correspond to an integrated luminosity of 19.7 fb[superscript ...

A measurement is presented of the t[bar over t] production cross section (σ[subscript t[bar over t]]) in proton-proton collisions at a centre-of-mass energy of 7 TeV, in the all-jet final state that contains at least ...

A search for narrow resonances decaying to bottom quark-antiquark pairs is presented, using a data sample of proton-proton collisions at √s=8  TeV corresponding to an integrated luminosity of 19.7  fb[superscript −1]. The ...

A search for supersymmetry (SUSY) is performed in final states comprising one or more jets and missing transverse momentum using data from proton-proton collisions at a centre-of-mass energy of 13 TeV. The data were recorded ...

An inclusive search for the standard model Higgs boson (H) produced with large transverse momentum (pT) and decaying to a bottom quark-antiquark pair (bb) is performed using a data set of pp collisions at √s = 13 TeV ...
