Session B10 - Searches for New Particles I.
FOCUS session, Saturday morning, April 28
Room 3, Renaissance Hotel$
We report preliminary results from the rare particle search experiment E896 which studied particle production from Au+Au interactions at 11 GeV/nucleon at the BNL AGS. This experiment was designed to measure \Lambda polarization and to search for the H dibaryon, a 6 quark (uuddss) particle predicted by Jaffe in 1977, which is expected to be stable with respect to strong decays. E896 consists of a 6.2 T superconducting sweeping magnet, holding a 15 plane Si tracking array, followed by a conventional 1.6 T magnet holding a 144 plane drift chamber. Data from the two tracking detectors have been analysed for \Lambda decays and for the topological signature of an H decay to a \Sigma^- and a proton. Details of the analysis and preliminary results are presented.
