Equivalence Principle parity violation tests
Gravitation is parity symmetric or antisymmetric. Mass distribution parity divergence varies from χ = 0 (achiral) to χ = 1 (perfect). A parity Eötvös experiment contrasts chemically and macroscopically identical enantiomorphic space groups P3121 and P3221 α-quartz single crystal test masses. A parity calorimetry experiment contrasts P3121 and P3221 benzil single crystals enthalpies of fusion. ...
متن کاملEffects of isospin-symmetry violation on tests of the standard model using parity-violating electron scattering
The effects of isospin-symmetry breaking on the observables for parityviolating electron scattering are investigated within the framework of the nuclear shell model for 12C, 16O, and 28Si. Contributions due to mixing with low-lying states as well as admixtures of 1p− 1h configurations (via the radial wave functions) are accounted for. It is found that isospin-mixing can be important, and the co...
متن کاملNeutrino Masses in the Supersymmetric Standard Model with Right-Handed Neutrinos and Spontaneous R-Parity Violation
We propose an extension of the supersymmetric standard model with righthanded neutrinos and a singlet Higgs field, and study the neutrino masses in this model. The Majorana masses for the right-handed neutrinos are generated around the supersymmetry breaking scale through the vacuum expectation value of the singlet Higgs field. This model may induce spontaneous R-parity violation via the vacuum...
متن کاملFurther 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...
متن کاملR - Parity Violation and Quark Flavour Violation
We investigate the implications of R-Parity violation (RPV) for quark flavour violation both by constraining the sneutrino masses to be positive and by studying the processes b → sγ and K − K̄ mixing. In the latter there are two major contributions, one from “direct” one loop diagrams involving RPV couplings, and one from the “indirect” contributions generated by the renormalisation group. We co...
