Uniformly rigid homeomorphisms
… of dynamical systems that display rigidity and weak mixing. We are particularly interested in the topological analogue of rigidity, called uniform rigidity. A map $T$ defined on a topological space $X$ is called \textit{uniformly rigid} if there exists an increasing sequence of natural numbers …

Single Neutral Pion Production in Charged Current and Neutral Current Neutrino Interactions
… of this ratio can be related to the Weinberg weak-mixing angle $\theta\sb{w}$, yielding a value of sin$\sp2\theta\sb{w}$ = 0.256 $\pm$ 0.156.

First determination of the weak charge of the proton
The Qweak experiment measures the parity violating asymmetry in elastic e[upper script right arrow]p scattering at Q² = 0.02455 (GeV/c)² with a 180 [mu]A and 88.7% longitudinally polarized electron beam of 1.165 GeV and a 34.4 cm liquid hydrogen target in experimental Hall C at Jefferson Lab. As …

Standard model physics and beyond in low energy neutrino scattering and parity violating electron interactions with nuclei
… performing combined analyses of different electroweak probes is a powerful tool to extract fully data-driven information. Indeed, I studied the physics of parity-violating electron scattering off nuclei and the atomic parity-violation process, which permit the extraction of complementary …

Measuring the Weak Charge of the Proton and the Hadronic Parity Violation of the N →Δ Transition
Qweak will determine the weak charge of the proton, QpW, via an asymmetry measurement of parity-violating elastic electron-proton scattering at low four momentum transfer to a precision of 4%. QpW has firm Standard Model prediction and is related to the weak mixing angle, sin20W, a well-defined …

Parity-Violating Elastic Electron Nucleon Scattering: Measurement of the Strange Quark Content of the Nucleon and Towards a Measurement of the Weak Charge of the Proton
… Jefferson National Accelerator Facility. Q<sub>weak</sub> will measure the weak mixing angle, sin²θ<sub>W</sub>, via a measurement of the weak charge of the proton, at a four-momentum transfer, Q² ~ 0.026 GeV²/c². The precision of this measurement gives Q<sub>weak</sub> access to new physics at …
