  1. 11. Quark Distributions and Charged Higgs Boson Production : Studies of Proton Structure and New Physics

    Författare :Johan Alwall; Gunnar Ingelman; Johan Rathsman; Dieter Zeppenfeld; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; quark distributions; parton density functions; proton structure; strange quark; intrinsic charm; charged Higgs boson; supersymmetry; NuTeV; LHC; parton showers; matrix element; elementary particle physics; Fysik; Physics; Fysik;

    Sammanfattning : The Standard Model describes all elementary particles known today, but at larger energies it will have to be complemented with new particles and interactions. To be able to distinguish new physics at proton colliders such as LHC at CERN, it is essential to have an appropriate description of the colliding protons and their interactions. LÄS MER

  2. 12. η Meson Production in Proton-Proton Collisions at Excess Energies of 40 and 72 MeV

    Författare :Henrik Petrén; Tord Johansson; Pawel Moskal; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Elementary particle physics; Elementarpartikelfysik; Nuclear Physics; kärnfysik;

    Sammanfattning : The production of η mesons in proton-proton collisions has been studied with the WASA detector using internal pellet targets in the CELSIUS storage ring at the The Svedberg Laboratory in Uppsala. Data were taken at two beam energies, 1360 MeV and 1445 MeV, corresponding to CM excess energies of 40 and 72 MeV, respectively. LÄS MER

  4. 14. Phenomenology of Charged Higgs Bosons and B-meson Decays

    Författare :David Eriksson; Johan Rathsman; Gunnar Ingelman; Fabio Maltoni; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; Beyond Standard Model; B-Physics; Charged Higgs Boson; LHC; QCD; Spin Correlations; CMSSM; NUHM; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : For more than 30 years the Standard Model has been the theoretical foundation for particle physics. The theory has been verified successfully by experimental tests. Its biggest shortcoming is the non-discovery of the Higgs boson,responsible for giving the other particles masses. LÄS MER

  5. 15. Statistical and Dynamical Aspects of Intermediate Energy Nuclear Collisions

    Författare :Roberta Ghetti; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; excitation function.; subthreshold pions; pion production; neutron cross-talk; correlation function; interferometry; intermittency; phase transition; thermal scaling; reducibility; multifragmentation; Heavy ion collisions; intermediate energy; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1997:Ghetti;

    Sammanfattning : Studies of intermediate energy heavy ion reactions have revealed the existence of a number of reducibility and thermal scaling properties in nuclear multifragmentation. In particular, the probability of emitting n-fragments is reducible to the probability of emitting a single fragment through the binomial distribution. LÄS MER
