LEPTONIC DECAY OF A $Sigma$$sup -$ HYPERON
Journal Article

· Phys. Rev. Letters
An example of the leptonic decay of a hyperon SIGMA /sup -/ yields e/ sup -/ + nu + n is reported. The interaction is obtained by exposing a 30 in. propane chamber to a 2 Bev pi /sup -/ beam. It is hypothesized that the SIGMA is produced by the reaction pi /sup -/ + p yields SIGMA /sup -/ + K/sup 0/ + pi /sup +/, and that the SIGMA /sup -/ decays by beta /sup -/ emission. Alternativ e decay processes, in which the SIGMA /sup -/ decays by irteracting with a proton, are rejected because of energy or probability considerations. (T.F.H.)
