... (i.e., renormalizable) quantum field theory can include only spin 0, 1/2, and 1. Renormalizable interactions are only those interactions that can appear without extra suppressions of GN E 2 /h̄c5 = (E/1019 GeV)2 1. Therefore, there is a reason why we see only particles of spin 1/2 and 1. Well, wha ...

The presented work is naturally divided into two parts, the first is concerning elastic scattering while the second explores inelastic scattering. In the first part we use a scattering-matrix formalism combined with results from random- ...
