Strange quark contribution to the nucleon.
(2007-02-07)The strangeness contribution to the electric and magnetic properties of the nucleon has been under investigation experimentally for many years. Lattice Quantum Chromodynamics (LQCD) gives theoretical predictions of these ... -
Gravitational collapse and formation of black holes in the Brans-Dicke theory of gravity with (2+1) dimensions.
(2008-03-03)In this thesis, the gravitational collapse of the Brans-Dicke scalar field and formation of black holes in 2+1 Gravity is examined. In contrast to general relativity, there are two conformally related frames in the ... -
Investigation into compactifed dimensions: Casimir energies and phenomenological aspects.
(2009-01-07)A central theme in this dissertation is the notion of the quantum vacuum. To a particle physicist, the term 'vacuum' means the ground state of a theory. In general, this ground state must obey Lorentz invariance, at least ... -

(2009-04-01)The total electron scattering cross sections of Tetrafluoromethane, Trifluoromethane, Hexafluoroethane, and Octafluorocyclobutane are measured in the energy range 0.10 to 4.50 keV using the linear transmission technique. ... -
Characteristic measurements within a GEC rf Reference Cell.
(2010-10-08)Since its introduction, the GEC rf Reference Cell has provided a baseline for comparison among various experiments performed within the complex (dusty) plasma community. The GEC cell, while providing for data comparison ... -
Surface embedded green function method applied to Ag(111).
(2010-10-08)Theoretical self-consistent calculations utilizing the Surface Embedded Green Function (SEGF) method have been performed on the Ag(111) surface. Analysis of the surface energetics reveal an energy minimum in the low ... -
Nanomanipulator perturbation of dust crystals in a GEC rf plasma cell.
(2010-10-08)The vast majority of observable matter is composed of complex plasma. Even with its prevalence, the interactions between the plasma's constituents are not fully understood. In many cases, clouds of dust grains from and can ... -
Investigation of low Higgs models in Weakly Coupled Free Fermionic Heterotic String Theory.
(2010-10-08)Superstring phenomenology explores classes of vacua which can reproduce the Standard Model at low energy. We consider Weakly Coupled Free Fermionic Heterotic String Theory (WCFFHST) which produces four dimensional Standard-like ... -
A search for the standard model Higgs boson produced in association with a W boson.
