Abstract

We have studied the Dalitz plot for the recently observed charged state decaying into Kâ>π±π± at 1876 MeV/c2 and we find that the final state is incompatible with a natural spin and parity assignment. This information, coupled with the earlier observation of the K±πâ> decay mode (a final state of natural spin and parity) of the neutral state at 1865 MeV/c2, suggest parity nonconservation in the decays of these objects if they are members of the same isomultiplet as their proximity in mass suggests.
