Parity violation and the nature of charges
The origin of parity violation in physics is still unknown. At the present time, it is introduced in the theory by requiring that the SU(2) subgroup entering the description of interactions involves the left components. In the present contribution, one elaborates upon a suggestion made by Landau that particles and antiparticles could be like “stereo-isomeric” molecules, which would naturally pr...
متن کاملSymmetry Violation in Heavy Nuclei
For a long time heavy nuclei were considered for the study of symmetry violations mostly due to enhancement factors related to the complex nuclear structure. Classical examples are experiments that measure parity violating correlations in nuclear decays and in nuclear reactions. It is well known that due to nuclear enhancements the parity violating effects in nuclei could be as large as ∼ 10 in...
متن کاملNeutrino and Parity Violation in Weak Interaction
It is shown that neutrino oscillation and Majorana type neutrino are not compatible with Special Theory of Relativity. Instead of the Majorana type neutrino, traditional neutrino (mν = 0) is considered with additional assumptions that νR and ν̄L neutrinos exist in nature and naturally thus parity is conserved. Besides, neutrino itself is considered as longitudinal vacuum-string oscillations. To ...
متن کاملAtomic Parity-Violation in Highly-Charged Ions
The investigation of parity-violation (PV) in forbidden atomic transitions is an active and fundamental research area, especially for its implications on the physics beyond the Standard Model [1]. Atomic transitions may be employed to study PV effects originating from weak neutral currents, i.e. due to the exchange of a Z boson between a nucleon of the nucleus and a bound electron. Experiments ...
متن کاملTheoretical overview of atomic parity violation
Recent advances in interpreting the most accurate to-date measurement of atomic parity violation in Cs are reviewed. The inferred nuclear weak charge, QW ( Cs) = −72.65(28)expt(36)theor, agrees with the prediction of the standard model at 1σ level. Further improved interpretation is limited by an accuracy of solving basic correlation problem of atomic structure. We report on our progress in sol...
