Abstract
E896 was designed to search for the predicted short-lived six-quark Ho diba ryon. The goal is to enhance the existing knowledge by extending the search into regions of shorter lifetimes (approximately half that of the lambda) and via exploring a new creation channel, that of the coalescence of two la mbdas. Two main tracking chambers are used, a distributed drift chamber pos itioned to measure low-p, and high-rapidity neutral particle decay products and a silicon drift detector array which measures particle production at m id-rapidity. Both detectors are also investigating lambda polarization, ove r their respective coverages, for Au-Au collisions at 11.3 GeV/nucleon. The current status of the Ho di-baryon search and preliminary results of the s trange particle production and polarization measurements will be presented.
