Macroscopic Parity Violation and Supernova Asymmetries

چکیده

Core collapse supernovae are dominated by weakly interacting neutrinos. This provides a unique opportunity for macroscopic parity violation. We speculate that parity violation in a strong magnetic field can lead to an asymmetry in the explosion and a recoil of the newly formed neutron star. We estimate the size of this asymmetry from neutrino polarized neutron elastic scattering, polarized electron capture and neutrino-nucleus elastic scattering in a (partially) polarized electron gas.

Parity Violation in Neutron Capture Reactions

In the last decade, the scattering of polarized neutrons on compound nucleus resonances proved to be a powerful experimental technique for probing nuclear parity violation. Longitudinal analyzing powers in neutron transmission measurements on p-wave resonances in nuclei such as La and Th were found to be as large as 10%. Here we examine the possibilities of carrying out a parallel program to me...

Bs Mesons in the MSSM with R-parity Violation

Motivated by the possible large direct CP asymmetry of B̄0 d → D + D − decay measured by Belle collaboration, we investigate double charm Bu,d and Bs decays in the minimal supersymmetric standard model with R-parity violation. We derive the bounds on relevant R-parity violating couplings from the current experimental data, which show quite consistent measurements among relative collaborations. U...

2 00 5 A luminosity monitor for the A 4 parity violation experiment at MAMI

A water Cherenkov luminosity monitor system with associated electronics has been developed for the A4 parity violation experiment at MAMI. The detector system measures the luminosity of the hydrogen target hit by the MAMI electron beam and monitors the stability of the liquid hydrogen target. Both is required for the precise study of the count rate asymmetries in the scattering of longitudinall...

Further Tests of Parity Violation in Inelastic Electron Scattering

Further measurements of parity violating asymmetries in inelastic scattering of polarized electrons from deuterium have been made for a range of y values from 0.15 to 0.36. Only a small y-dependence is observed in the asymmetries. Using the quark-parton model our results are in good agreement with the Weinberg-Salam predictions. 0.020. We obtain a value of the parameter sin2f3W= 0.224 ?r The ev...

Target Density Fluctuation Monitoring in the HAPPEX Helium Parity Violation Experiment

Luminosity monitors were used to study density fluctuations in the cold helium-4 target of the HAPPEX-He parity violation experiment in Jefferson Lab Hall A. Helicity-correlated asymmetries were measured as beam current, beam raster size, target fan speed, and target density were varied. These studies were used to determine optimal running conditions and estimate the contribution of target dens...
