Schumacher, R A

In this talk I will summarize the motivation for H-dibaryon searches and describe efforts at Brookhaven to find this particle. The most recently run experiment, using a new 2 GeV/c kaon beam line, has looked for the H in the at-rest formation reaction ({Xi}{sup {minus}} + d){sub atom} {r arrow} H + n, where the monoenergetic neutron was detected. This experiment is sensitive to an H in the range near the {Lambda}{Lambda} mass, a region largely unconstrained by other measurements. Data analysis is in progress, so no results are available yet. A second search technique using a {sup 3}He target is also described.
