Strangelet search in Au plus Au collisions at root s(NN)=200 GeV

Grosnick, D. D.; Ullrich, T; STAR Collaboration

Abstract

We have searched for strangelets in a triggered sample of 61 million central (top 4%) Au+Au collisions at root s(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 >= 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(-6) to 10(-7) per central Au+Au collision are set for strangelets with mass greater than or similar to 30 GeV/c(2).
