A nonperturbative description of Nanti N annihilation
Description
A nonperturbative picture of Nanti N annihilation is proposed. In particular, different parts of the nucleon and the antinucleon do not behave independently, but are tied together by their topological charge. We describe the Nanti N state as a coherent soliton-antisoliton configuration, and argue that vector mesons play an important role in the decay process. Some S-wave selection rules are derived. Their relevance to the present LEAR experiments is discussed. (orig.)
