TLDR

In this article, a general formulation for constructing covariant helicity-coupling amplitudes involving two-body decays with arbitrary integer spins is given, and the decay amplitudes are given exclusively in terms of both definite orbital angular momentum and total intrinsic spin.

Abstract:

A general formulation is given for constructing covariant helicity-coupling amplitudes involving two-body decays with arbitrary integer spins. The decay amplitudes are given exclusively in terms of both definite orbital angular momentum and total intrinsic spin. A systematic method is developed for calculating the energy and momentum dependence of daughter particles in the decay amplitudes, and a general formula for arbitrary integer spins is given. A number of illustrative examples is worked out, among which is that of the Higgs boson decay into two gauge bosons.
