CROSSING RELATIONS FOR HELICITY AMPLITUDES

Journal Article · · Annals of Physics (New York) (U.S.)
;
Crossing relations for helicity amplitudes for particles of arbitrary spin are formulated without recourse to the introduction of scalar amplitudes. The basic assumption is that the amplitudes are simply related by analytic continuation; the path of continuation is carefully specified. The relations are given a simple geometrical interpretation. The relation between pi N yields pi N and pi pi yields NN obtained in this lar amplitudes. (auth)
