Description
The difficulties associated with relativistic two-body equations, both classical and quantum mechanical, will be discussed. Two approaches to the two-body Dirac equation will then be considered. The emphasis will be on the Breit version of this equation with instantaneous interaction. This equation will be solved for quarkonium states using a standard potential with short-range and linear terms, with a particular emphasis on the vector-scalar mix in the linear potential. The energy of the 0-
state of charmonium will be calculated as an example. Much of
this material is accessible to upper-division undergraduates.
