ON THE Q-VALUES OF THE /cap lamba/$sup 0$ AND THE /theta/$sup 0$ AND ON THE ANOMALOUS V$sup 0$-DECAYS
A study of 161 V/sup 0/-decays observed in the momentum chamber of the Ecole Polytechnique at the Pic du Midi has been made. These events correspond to a strict choice based on the measurability of the momenta of both secondaries (better than 10%). The main results are: No direct evidence for anomalous neutral hyperon decays. Upper limits (6 to 8%) can be placed on the existence of various hypothetical modes. The Q-values for the LAMBDA /sup 0/-decay: Q LAMBDA /sup 0/ = (37.9 plus or minus 0.4) Mev. The direct identification of the pi natare of both secondaries of the THETA /sup 0/-decay-mode. The Qvalue for THETA /sup0/-decay: Q/sub TT/sup 0/ = (217 plus or minus 4) Mev. A direct proof of the non identity of the particles responsible for the THETA /sup 0/ decay and the anomalous nu /sup 0/-decays based on the significant difference between the number of slow and fast events of each category.
