Classical antiparticles
We review how antiparticles may be introduced in classical relativistic mechanics, and emphasize that many of their paradoxical properties can be more transparently understood in the classical than in the quantum domain.
متن کامل0 v 1 2 3 D ec 1 99 7 Classical antiparticles , quantum supersymmetry anomaly and constituent models
The two ways of constrained systems quantization are considered from the point of view of their self-consistency at the quantum level. With a transparent example of a particle in the external electromagnetic field we demonstrate that the procedure of gauge fixing turns out rather dangerous and may lead to a quantum anomaly in the operator algebra. We discuss additional classical symmetries as a...
متن کاملPoint form relativistic quantum mechanics, antiparticles and
Point form relativistic quantum mechanics, antiparticles and exchange currents. Abstract It is shown that the dynamical observables calculated with the point form rela-tivistic quantum mechanics incorporate effects of particle-antiparticle creation from the vacuum by interactions. The electromagnetic observables obtained with the point form impulse approximation include contributions from the "...
متن کاملHeavy Wino-like Neutralino Dark Matter Annihilation into Antiparticles
The lightest neutralino is a viable dark matter (DM) candidate. In this paper we study indirect detection of the wino-like neutralino DM using positrons and antiprotons from the annihilation in the galactic halo. When the mass is around 2 TeV, which is favored from the thermal relic abundance, the nonperturbation effect significantly enhances the annihilation cross sections into positrons and a...
متن کاملUniformly classical quasi-primary submodules
In this paper we introduce the notions of uniformly quasi-primary ideals and uniformly classical quasi-primary submodules that generalize the concepts of uniformly primary ideals and uniformly classical primary submodules; respectively. Several characterizations of classical quasi-primary and uniformly classical quasi-primary submodules are given. Then we investigate for a ring $R$, when any fi...
