    Phenomenological comparison of inelastic electron-proton scattering with reaction K+ p → K0 + anything at 5, 8.2 and 16 GeV/c

    We present an analysis of the reaction K+p → K0 + anything at incident momenta of 5, 8.2 and 16 GeV/c in terms of the Björken variables gw and x. Assuming dominance of ρ{variant} exchange, we derive the structure function F2(x, y) which is found similar to the one obtained in deep inelastic electroproduction. © 1976.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

    Associated average charged particle multiplicities in K+pK^+p interactions at 32 GeV/c

    No full text
    The average charged particle multiplicities, 〈nR(MX2)〉, in the reactions K+p → π-X and K+p → K0X at 32 GeV/c are studied as functions of the mass squared MX2 of the "associated" system X. A comparison with the corresponding results obtained at lower incident momenta is presented. © 1976.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

    A New Boson with a Mass of 125 GeV Observed with the CMS Experiment at the Large Hadron Collider

    The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would verify the existence of a complex scalar field thought to give mass to three of the carriers of the electroweak force-the W+, W-, and Z(0) bosons-as well as to the fundamental quarks and leptons. The CMS Collaboration has observed, with a statistical significance of five standard deviations, a new particle produced in proton-proton collisions at the Large Hadron Collider at CERN. The evidence is strongest in the diphoton and four-lepton (electrons and/or muons) final states, which provide the best mass resolution in the CMS detector. The probability of the observed signal being due to a random fluctuation of the background is about 1 in 3 x 10(6). The new particle is a boson with spin not equal to 1 and has a mass of about 1.25 giga-electron volts. Although its measured properties are, within the uncertainties of the present data, consistent with those expected of the Higgs boson, more data are needed to elucidate the precise nature of the new particle
