Ordered S-Matrix Approach to the Topological Expansion for Baryons and Mesons.

摘要

A proposal is made for extending to processes involving baryons the ordered Hilbert space approach to the topological expansion. The proposal is based on a topological classification scheme for baryonic processes that is similar to one used previously for the lowest-order contributions,but is in terms of the minimum number of reggeon closed loops instead of handles.
