Strangelet search in AuAu collisions at {radical}{ovr s}{sub NN} = GeV.
We have searched for strangelets in a triggered sample of 61 million central (top 4%) Au+Au collisions at {radical}s{sub NN} = 200 GeV near beam rapidities at the STAR solenoidal tracker detector at the BNL Relativistic Heavy Ion Collider. We have sensitivity to metastable strangelets with lifetimes of order = {ge} 0.1 ns, in contrast to limits over ten times longer in BNL Alternating Gradient Synchrotron (AGS) studies and longer still at the CERN Super Proton Synchrotron (SPS). Upper limits of a few 10{sup -6} to 10{sup -7} per central Au+Au collision are set for strangelets with mass {approx}> 30 GeV/c{sup 2}.
