H. Caines, An update on the strangeness production measurements and H-0 di-baryon search as performed by the AGS experiment 896, J PHYS G-NU, 27(3), 2001, pp. 311-318
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.
