Harmonic analysis in terms of the homogeneous Lorentz group
Abstract
Scattering amplitudes for particles of arbitrary mass and spin are expanded in terms of homogeneous Lorentz group representations. The expansion satisfies the group theoretic O(3,1) boundary constraints in the forward elastic limit and incorporates the correct threshold factors.
