We present the calculation of Next-to-Leading-Order Quantum Chromo Dynamics corrections for the production of W or Z weak bosons associated with a bottom anti-bottom quark pair at hadron colliders (ppbar, pp to W/Z bbbar), including the...
This dissertation examines the observability of neutralino dark matter in the context of supersymmetric models constrained constrained by the recent WMAP data on the relic density of cold dark matter. The neutralino-nucleon scattering...
Supersymmetric grand unified models based on the SO(10) gauge group are especially attractive in light of recent data on neutrino masses. The simplest SO(10) SUSY GUT models predict unification of third generation Yukawa couplings (t –b ...
Understanding Type Ia Supernovae provides an opportunity to study a wide range of modern physics as well as develop a key tool in cosmology. Here, we identify and investigate new observational signatures of underlying physical processes...
This dissertation describes a measurement of the muon charge asymmetry from W boson decays. The charge asymmetry provides useful information about the momentum distribution of u and d quarks inside the proton. The charge asymmetry was...
SUSY is one of the most promising new physics ideas, and will soon be tested at high energy accelerators like the CERN LHC. Moreover SUSY provides a good candidate for cold dark matter (CDM). In this dissertation, we investigated...
Clustering of α particles plays an important role in light atomic nuclei. For example, multicenter structures built on the well-known low-lying states of 8Be can be formed. The addition of nucleons to the system may result in covalent...
This thesis addresses the role of topology and geometry in quantum gravity. A major topic will be how inequivalent differentiable structures (exotic smoothness) can play a physically significant role in both semiclassical gravity and...
I study thermonuclear explosions of White Dwarf (WD) stars, or so-called Type Ia supernovae (SNe Ia). A WD is the final stage of stellar evolution of a star with an initial mass of less than 8 Solar masses, and the thermonuclear...
Several models of new physics yield particles that are massive, long-lived, and have an electric charge, Q, greater than that of the electron, e. A search for evidence of such particles was performed using 5.0 fb-1 and 18.8 fb-1 of...
In this work, we study the phenomenology of direct photon production using theoretical predictions at next-to-leading order with threshold resummation up to next-to-leading- logarithmic accuracy . By analyzing the global data sets of...
