QFT, Antimatter, and Symmetry
arXiv:0903.3018 · doi:10.1016/j.shpsb.2009.07.002
Abstract
A systematic analysis is made of the relations between the symmetries of a classical field and the symmetries of the one-particle quantum system that results from quantizing that field in regimes where interactions are weak. The results are applied to gain a greater insight into the phenomenon of antimatter.
