Two body decay width
WebJan 8, 2024 · so 68% of the decay modes are hadronic. That means that the quark antiquark pairs dress themselves up into several hadrons, which are themselves unstable, so they, in turn, decay to many particles. These multi particle decays are included in the 2-body primary decays. A higher-order fundamental vertex, such as WWγ, where the off-shell W would ...
