Parity Violation in Hadronic Systems
Our present understanding of the AS=O hadronic weak interaction is based on a collection of high precision experiments in the two-nucleon system and light nuclei, which isolate the weak interaction via its parity-violating signature. The weak nucleon-nucleon interaction at low and intermediate energies is described in terms of a meson exchange model involving n, p and W mesons, with one strong ...
متن کاملThe Influence of Cation-π Interactions on the Strength and Nature of Intramolecular O...H Hydrogen Bond in Orthohydroxy Benzaldehyde Compound
The influence of cation-π interactions on the strength and nature of intramolecular O...H hydrogen bond has been investigated by quantum chemical calculations in orthohydroxy benzaldehyde (HBA) compound. Ab initio calculations have been performed at MP2/6-311++G** level of theory. Vibrational frequencies and physical properties such as chemical potential and chemical hardness of these compounds...
متن کاملSpin Effects in the Weak Interaction
Modern experiments investigating the beta decay of the neutron and light nuclei are still provide important constraints on the theory of the weak interaction. Beta decay experiments are yielding more precise values for allowed and induced weak coupling constants and putting constraints on possible extensions to the standard electroweak model. Here we emphasize the implications of recent experim...
متن کاملA pr 1 99 8 Progress toward a new measurement of the parity violating asymmetry in ~ n + p → d + γ
Progress toward a new measurement of the parity violating asymmetry in n + p → d + γ Abstract We outline the motivation and conceptual design for a new experiment aimed at a 10-fold improvement in the accuracy of the parity-violating asymmetry A γ in the angular distribution of 2.2 MeV gamma rays from the n + p → d + γ reaction. This observable is primarily sensitive to the weak pion-nucleon co...
متن کاملImplications of Weak-Interaction Space Deformation for Neutrino Mass Measurements
The negative values for the squares of both electron and muon neutrino masses obtained in recent experiments are explained as a possible consequence of a change in metric within the weak-interaction volume in the energy-momentum representation. Using a model inspired by a combination of the general theory of relativity and the theory of deformation for continuous media, it is shown that the neg...
