Measurements are presented of the production of primary ${K}_{S}^{0}$ and $\ensuremath{\Lambda}$ particles in proton-proton collisions at $\sqrt{s}=7\text{ }\text{ }\mathrm{TeV}$ in the region transverse to the leading charged-particle jet in each event. The average multiplicity and average scalar transverse momentum sum of ${K}_{S}^{0}$ …

Abstract A search for the standard model Higgs boson produced in association with a top-quark pair is presented using data samples corresponding to an integrated luminosity of 5.0 fb−1 (5.1 fb−1) collected in pp collisions at the center-of-mass energy of 7 TeV …

In this paper, a search for supersymmetry (SUSY) is presented in events with two opposite-sign isolated leptons in the final state, accompanied by hadronic jets and missing transverse energy. An artificial neural network is employed to discriminate possible SUSY signals from a …
