The determination of the spin and parity of a vector-vector system

We present a construction of the reaction amplitude for the inclusive production of a resonance decaying to a pair of identical vector particles such as $J/\psi J/\psi$, $\rho\rho$, $\phi\phi$, or $ZZ$. The method provides the possibility of determining the spin and parity of a resonance in a model-independent way. A test of the methodology is demonstrated using the Standard Model decay of the Higgs boson to four leptons.
