The proton's longitudinal spin structure studied through the weak interaction in pp collisions
… In this measurement, the parity violating weak interaction serves, compared to than previously used techniques, as a cleaner and more direct probe of flavor separated quark and antiquark spin-dependent momentum distributions. This is most significant in the case of the antiquark …

A search for parity non-conservation in polarized proton-nucleon scattering at 6 GEV/C
… helicity is a measure of the strength of the weak interaction in the hadronic system. The cross section was determined by measuring the transmission of 6 GeVlc polarized (-26.3 ± 7.5) 10 where 0 (0) is the total section for positive protons through an H20 target. integral counting techniques …

Analysis of B Meson Decays to Three Charged Pions
… final states probe the properties of the weak interaction through their dependence on the complex quark couplings in the CKM matrix. They also test dynamical models for hadronic B decays. Based on a sample of 772 million BB pairs collected by the Belle experiment, we present a study of …

Weak Decay Studies From An Effective Theory Standpoint
… dissertation I discuss the phenomenology of some weak interaction decays using a model independent approach by employing effective field theories. I discuss the soft photon contribution and background effect to the rare dimuonic decay of the neutral B meson. I also study some radiative exclusive W …

Radioactive source measurements in a liquid xenon time projection chamber
… double beta decay, which is a second-order weak interaction process and has already been observed in several nuclei. The second one is called neutrino less double beta decay. This is a yet-to-be observed lepton number violating process, which can only be described by new physics, not …

Inclusive and Exclusive Compton Processes in Quantum Chromodynamics
… an extension of this particular process into the weak interaction sector. We also investigate a possible application of the GPD formalism to wide-angle real Compton scattering.</p>

A MEASUREMENT OF THE NEUTRAL CURRENT NEUTRINO-NUCLEON ELASTIC CROSS SECTION AT MINIBOONE
The neutral current neutrino-nucleon elastic interaction ν N [arrow right] ν N is a fundamental process of the weak interaction ideally suited for characterizing the structure of the nucleon neutral weak current. This process comprises ∼18% of neutrino events in the neutrino oscillation experiment, …

On subharmonic instability in boundary layers
… It is found that in the presence of a strong interaction (e.g., large amplitude of the two-dimensional wave), results from the resonant triad model are inaccurate as compared with the experimental data and the t results from the parametric instability model. This is mainly because the resonant …

A test of the Delta S = Delta Q selection rule in K°e3 decay
… ZGS to test the validity of the 6S = t:P. weak interaction selection rule for the decay KAn experiment was performed at the Argonne ZGS to test the validity of the 6S = t:P. weak interaction selection rule for the decay [equation] K mesons were produced by a 3 GeV beam on a carbon target in …

Measurement of W Boson Polarization in Top Quark Decay
… test of the V-A form of the charged-current weak interaction in the standard model. Since the longitudinal W boson is intimately related to the electroweak symmetry breaking mechanism, and the standard model gives a specific prediction for the fraction longitudinal W bosons from top decays, …

Some Aspects of Symmetry Breaking in Unified Weak-Electromagnetic Gauge Theories
… on some problems of symmetry breaking in unified weak-electromagnetic gauge theories. In Chapter I we set the scene with a brief history of weak interaction theory up until the impasse which led to the development of the unified weak-electromagnetic gauge theory strategy. In Chapter 2 we describe …

Force studies of multiple kinesin-1 and EG5 molecular motors
… the number of motors bound and that Eg5 has a weaker binding than that of kinesin -1. The stiffuess for the motor domains is comparable, yet we find that the average time to rebind for Eg5 decreases at higher concentrations while it does not for kinesin-1. This may indicate that there exists …

Yeast two-hybrid analysis of skeletal muscle triad junction proteins
… yeast two-hybrid system was used to search for interactions among known and novel proteins of triad junctions. In direct interaction tests, no strong interaction was detected between the dihydropyridine receptor (DHPR) II-III loop and the skeletal muscle ryanodine receptor (RyR); however, a …

Characterization of novel genetic alleles of cellulose synthase
… primary cell wall cellulose synthases. Paired interaction studies determined that CESA1 interacts strongly with itself. Also, CESA3 interacts strongly with itself. However, interaction between CESA1 and 3 was weak. It is possible that a tertiary protein is required in order for this interaction …
