Symmetry breaking induced by top quark loops from a model without scalar mass. Abstract Considering the standard model as an eeective electroweak theory, in which we have no scalar mass term in the Higgs potential (2 = 0), we show that the spontaneous symmetry breaking of SU(2) L U(1) can be induced by top loops. The Higgs boson mass obtained is smaller than 300 GeV.

We calculate the exact tree-level scalar mass matrices resulting from symmetry breaking using the most general gauge-invariant scalar potential of the 331 model, both with and without the condition that lepton number is conserved. Physical masses are also obtained in some cases, as well as couplings to standard and exotic gauge bosons.

We review the motivation for Gauge-Mediated Supersymmetry Breaking and discuss some recent advances.

We consider inflaton couplings to MSSM flat directions and the thermalization of the inflaton decay products, taking into account gauge symmetry breaking due to flat direction condensates. We then search for a suitable curvaton candidate among the flat directions, requiring an early thermally induced start for the flat direction oscillations to facilitate the necessary curvaton energy density d...

Abstract The scientific article shows the application of method continuous wavelet data transform to estimate soil breaking up when tilling. Due high speed experimental processing, it became possible reduce total time section scanning for determining its agrotechnical parameters. reduction is achieved by both choosing type spiral along which performed and angular velocity. On whole, twice as fa...

We have studied the predictions for the LSP decay within the framework of a radiatively broken unified supergravity model without R-parity. Assuming that Higgs/slepton mixing is the only source of R-parity breaking and responsible for the observed neutrino oscillations we obtain predictons for the LSP life-time and branching fractions.
