The Decay of a NeutralVParticle into Two Mesons

An unusual example of the decay of a neutral $V$ particle has been observed in a multiplate cloud chamber operated at 10 600 feet. From this event, it is uncertain if the decay is a two- or three-body process, though in either case neither of the charged decay products can be as heavy as a proton. If we assume a two-body decay, the event may be completely and consistently described according to either of the following decay schemes: ${V_2}^0\to \pi +\pi +Q$, ${V_2}^0\to \pi +\mu +Q$. The corresponding $Q$ values are approximately 185 Mev and 150 Mev, respectively.
