Realtiistic Aspects of Few-Body Physics

摘要

After a brief review of alternative approaches to the relativistic treatment of few-body problems, I discuss (1) recent progress in the study of NN and NNN systems, (2) a new method for solving the Bethe-Salpeter equation in Minkowski space, (3) new relativistic treatment of spin 3/2 fields, and (4) construction of conserved electromagnetic currents in a relativistic optical model.
