We present a four-component relativistic approach to describe the effects of nuclear spin-dependent parity-violating (PV) weak forces on spin-rotation (NSR) tensors. The formalism is derived within polarization propagator theory based Dirac–Coulomb Hamiltonian. Such calculations are important for planning and interpretation possible future experiments aimed at stringent tests standard model thr...

We extend the statistical reaction with memory approach to study off-diagonal spin and parity S-matrix energy autocorrelation in dissipative heavy-ion collisions. It is suggested that S-matrix spin and parity decoherence results in (i) damping of the coherent nuclear rotation and (ii) is a manifestation of quantum chaos in dissipative heavy-ion collisions.

Largely enhanced parity-violating effects observed in compound resonances induced by epithermal neutrons are currently attributed to the mixing of parity-unfavored partial amplitudes entrance channel states. Furthermore, it is proposed that same mechanism enhances parity-violation also breaking time-reversal-invariance nucleus. The entrance-channel induces energy-dependent spin-angular correlat...

The phenomenology of neutrino oscillations is extended to the neutron-antineutron oscillations predicted by the grand unified theories. There are six parameters in general describing the one-flavor oscillations: two real Majorana masses (of opposite signs), three Euler’s angles, and a phase multiplier χ. The sum of the Majorana masses, treated as a small parity-violating parameter ǫ, induces th...

Microscopic calculations show a strong parity dependence of the nuclear level density at low excitation energy of a nucleus. Previously, this dependence has either been neglected or only implemented in the initial and final channels of Hauser-Feshbach calculations. We present an indirect way to account for a full parity dependence in all steps of a reaction, including the one of the compound nu...
