Large samples of inclusively produced 8-, n- and H'(l530) events are pre- sented from a 1427 ev/pb exposure of the LASS spectrometer to an 11 GeV/c K- beam. Production characteristics of these states are compared with other data and shown to be consistent with hyperon exchange. Polarization of B- shows an increase in magnitude with both Feynman x and transverse momen- tum. The H- decay parameters are measured to be are = -0.40 f 0.03 and tDPH = (5f 10)'. R es&s of searches for higher mass hyperons are presented. The E-(1820) + 8" (1530)7r- d eta y is observed, while we fail to confirm the existence of the x+(3170).
