Search for Six-Quark State at BABAR Experiment

Six-quark combination uuddss are allowed by Quantum Chromodynamics (QCD). It could be deeply bound state that has eluded detection. The stable six-Quark state is a potentially Dark Matter candidate. Based on a data sample of 90 million of Upsilon(2S) and 110 million Upsilon(3S) decays collected by the BABAR Experiment. We report the first search for a stable Six-Quark state in the decay of Upsilon to S Lambdabar Lambdabar. These bounds set stringent limits on the existence of such exotic particles.
