General formulation of covariant helicity-coupling amplitudes
- Department of Physics, Brookhaven National Laboratory, Upton, New York 11973 (United States)
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. {copyright} {ital 1997} {ital The American Physical Society}
