Abstract
We report on the latest results in the search for positively charged strang elets from the E864 96/97 run at the AGS with sensitivity of about 8 x 10(- 9) per central collision. This contribution also contains new results of a search for highly charged strangelets with Z = +3. Production of light nucl ei, such as He-6 and Li-6, is presented as well. Measurements of yields of these rarely produced isotopes near midrapidity will help constrain the pro duction levels of strangelets via coalescence. E864 also measures antiproto n production which includes decays from antihyperons. Comparisons with anti proton yields measured by E878 as a function of centrality indicate a large antihyperon-to-antiproton ratio in central collisions.
