On the parity conservation in the reaction K−−p=Σ++π−

We have analyzed 143 protonic decays of Σ+, emerging from K− capture stars in nuclear emulsion, in order to detect the possible parity non conservation in the strong capture reaction. The forward-backward asymmetryA of the decay has been determined, obtaining the valueA=(4.4±7.8)%. This result is in accordance with the hypothesis of strict parity conservation.
