Reduction of the Salpeter equation for massless constituents
Abstract Different from the case of the limit, it is shown in this paper that in the ultrarelativistic limit, the L = j, j+1 wave components are large terms for both state with parity ȠP = (-1)j and state with parity ȠP = (-1)j+1. Moreover, it is found that the states with parity ȠP = (-1) j are degenerate with the states with parity ȠP = (-1) j +1 if the Lorentz structure of the interaction between the massless constituents is four-vector or time-component of four-vector. The scalar interaction violates this degeneracy.
