论文摘要
我们提出了反应幅度的结构，用于将共振衰减包含到一对相同的向量粒子，例如$ j/ψj/ψ$，$ρρ$，$ ϕ ϕ $。该方法提供了以独立于模型的方式确定共振的自旋和平价的可能性。使用希格斯玻色子对四个瘦素的标准模型衰变以及生产中的角相关性和$ j/ψ$对的衰减，证明了该方法。
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.
