This dissertation describes a measurement of the muon charge asymmetry from W&rarr&mu&nu decay using 7.3 fb-1 of data collected from April 2002 to July 2010 using the D0 detector at Fermi National Accelerator Laboratory. The measurement...
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...
Baryon and hybrid baryon wave functions were built from harmonic oscillator basis states with explicit flavor and color. The Relativized Constituent Quark Model was extended to calculate more baryon states. Improvements were made to the...
In this dissertation, we investigate the edge spin excitations and reconstructions of quantum Hall (QH) liquids. Edge spin reconstructions reflect the interplay of confining potential, electron-electron interaction, and Zeeman splitting...
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...
In this work, topics in physics beyond the standard model of high energy phyics relevant to the experimental studies at the Large Hadron Collider (LHC) at CERN are discussed. We introduce an effective theory to describe the dynamics of...
Reaction physics involving composite objects with internal degrees of freedom is an important subject since it is encountered in the context of nuclear processes like fusion, fission, particle decay, as well as many other branches of...
The CBELSA/TAPS experiment at the electron accelerator ELSA, in Bonn, Germany, was used in order to study the photoproduction of neutral pions off the proton with a linearly polarized photon beam; Neutral pions were reconstructed through...
Results are reported of a search for a deviation in the jet production cross section from the prediction of perturbative quantum chromodynamics at next-to-leading order. The search is conducted using a 7 TeV proton-proton data sample...
Precise knowledge of parton distribution functions (PDFs) is necessary to the accurate calculation of QCD observables initiated by hadrons. The deep inelastic scattering (DIS) and lepton pair production (LPP) processes are primary...
The Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity is one of the jewels of 20th century physics. In this theory, the superconducting state of a metal is understood in terms of the formation of electron pairs which condense...
