TRIPP 1962

Tripp, R.D.; Watson, M.B.; Ferro-Luzzi, M.;
Determination of the Parity
Phys. Rev. Lett. 8 (1962) 175;

Motivation
In a previous Letter we reported a hydrogen-bubble-chamber experiment on the K^-p interaction in the vicinity of 400 MeV/c incident K^- momentum. The existence of an excited hyperon of 1520 MeV mass and 16 MeV full width was established; the state was found to have isotopic spin 0, spin 3/2, even parity with respect to K^-p, and a overline KN : : 2 branching ratio of 3:5:1. In this Letter we report the study of the angular distributions and polarizations of the different charge states, from which we conclude that the Kp parity is odd.
