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

Abstract

Abstract 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/ψJ/ψ, ρρ, ϕϕ. The method provides the possibility of determining the spin and parity of a resonance in a model-independent way. The methodology is demonstrated using the Standard Model decay of the Higgs boson to four leptons and through angular correlations in the production and decays of J/ψ pairs.
