Violation of particle number conservation in theGWapproximation

Baryon Number Violation in Particle Decays

It has been argued in the past that in baryogenesis via out-of-equilibrium decays one must consider loop diagrams that contain more than one baryon number violating coupling. In this note we argue that the requirement with regard to baryon number violating couplings in loop diagrams is that the interaction between the intermediate on-shell particles and the final particles should correspond to ...

Particle Number Conservation in Tiie Massive Thirring Model

We computed parr-production and nontrivlal three-particle scattering amphtudes of the massive Thirring model in one loop approximation. They are found to be zero. In contrast to the massless Thirring model in the massive Thirring model an explicit solution is unknown. Methods [1] useful in the massless case cannot be applied because the axial current is not conserved. Moreover the S-matrix deri...

Effects of particle-number conservation on heat capacity of nuclei

K. Tanabe† Department of Physics, Faculty of Science, Saitama University, Sakura, Saitama 338-8570, Japan (Dated: June 8, 2005) Abstract By applying the particle-number projection to the finite-temperature BCS theory, the S-shaped heat capacity, which has recently been claimed to be a fingerprint of the superfluid-to-normal phase transition in nuclei, is reexamined. It is found that the particl...

Energy Conservation Violation by Modulation of Coherent States Energy Conservation Violation in Spatial Interference Effects

We present a generalized account of how one might achieve energy conservation violation with quantum coherence effects. The general setup involves a violation of energy conservation by means of a change to the preparation of a coherent quantum mechanical effect which causes a change to the probability distribution of the measurable statistics of an observable. We also present a simple theoretic...
