  • Elieff, Stefan H. P. (Halifax, N.S. : Saint Mary's University, 1998)
    Observational evidence and theoretical arguments indicate that most of the universe is made of dark matter. Supersymmetry, an extension of the standard model of particle interactions, provides a natural candidate for dark ...

  • MacInnis, David R. (David Robert), 1977- (Halifax, N.S. : Saint Mary's University, 2004)
    MacFadyen & Woosley (1999) have studied two models of a hypernova, where a hyper-accreting disk is created in the core of a star. Their code requires an accurate model of local energy loss given by neutrino emission. An ...

  • Butler, Malcolm; Malaney, R. A.; Starkman, G. D. (American Physical Society, 1994-06-01)
    Applying the phenomenon of neutrino lasing in the solar interior we show how the rate for the generic neutrino decay process [nu] [right arrow] fermion + boson can in principle be enhanced by many orders of magnitude over ...

  • Butler, Malcolm; Chen, Jiunn-Wei; Kong, Xinwei (American Physical Society, 2001-03)
    We study the four channels associated with neutrino-deuteron breakup reactions at next-to-next-to-leading order in effective field theory. We find that the total cross section is indeed converging for neutrino energies up ...

  • Butler, Malcolm; Chen, Jiunn-Wei (Elsevier Science, 2001-11)
    The proton–proton fusion process pp [right arrow] de[superscript +] v[subscript e] is calculated at threshold to fifth order in pionless effective field theory. There are two unknown two-body currents contributing at the ...

  • Mendes, Sandro de Oliveira (Halifax, N.S. : Saint Mary's University, 2001)
    We study the evolution of linear density perturbations in a cosmological background described by scalar-tensor theories (STT) of gravity. The evolution of the density contrast δ is obtained using the Jeans formalism for ...
