  5. 59. Discrete Gauge Symmetries and Proton Stability in grand unified theories
    Prof. Rabindra. N. Mohapatra (University of Maryland)
    17/12/2007, 11:00
    We discuss the results of a search for anomaly free Abelian Z_N discrete symmetries that lead to automatic R-parity conservation and prevents dangerous higher-dimensional proton decay operators in simple extensions of the minimal supersymmetric extension of the standard model (MSSM) based on the left-right symmetric group, the Pati-Salam group and SO(10). We require that the superpotential for...

  6. 60. B-aniti-B mixing and lepton flavor violation in supersymmetric grand unified models
    Dr Yukihiro Mimura (Texas A&M University)
    17/12/2007, 11:50
    We study B-anti-B mixing in grand unified SO(10), SU(5) models where the mixings among the second and third generation squarks arise due to the existence of flavor violating sources in the Dirac and Majorana couplings which are responsible for neutrino mixings. We find that when the branching ratio of tau->mu gamma decay is enhanced to be around the current experimental bound, B_s-anti-B...

  7. 87. Unparticle Dark Matter
    Dr Tatsuru Kikuchi (KEK)
    17/12/2007, 12:10
    Once a parity is introduced in unparticle physics, under which unparticle provided in a hidden conformal sector is odd while all Standard Model particles are even, unparticle can be a suitable candidate for the cold dark matter (CDM) in the present universe through its coupling to the Standard Model Higgs doublet. We find that for Higgs boson mass in the range, 114.4 GeV < m_h < 250 GeV, the...
