Measurement of J/ψ and ψ(2S) Prompt Double-Differential Cross Sections in pp Collisions at √s=7 TeV
(2015)Physical Review LettersThe double-differential cross sections of promptly produced J/ψ and ψ(2S) mesons are measured in pp collisions at √s=7 TeV, as a function of transverse momentum pT and absolute rapidity |y|. The analysis uses J/ψ and ψ(2S) dimuon samples collected by the CMS experiment, corresponding to integrated luminosities of 4.55 and 4.90 fb−1, respectively. The results are based on a two-dimensional analysis of the dimuon invariant mass and decay ...Journal Article -
Search for Top Squark and Higgsino Production Using Diphoton Higgs Boson Decays
(2014)Physical Review LettersResults are presented of a search for a “natural” supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top quark (the top squark) and the Higgs boson (Higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 fb−1 of proton-proton collision data at s=8 TeV, recorded in the CMS ...Journal Article
