Search for Dark Matter in Upsilon Decays at BABAR Experiment

Recent investigations have suggested that the singlet six-quark combination $uuddss$ may be a deeply bound state $S$, called Sexaquark. An essentially stable state $S$ is a potentially excellent Dark Matter candidate. We present the first search for a stable, doubly strange six-quark state in the decays of $Υ(4S) \to Λ\barΛ$. Based on a data sample of $Υ(2S)$ and $Υ(3S)$ decays collected by the BABAR Experiment we report the most recent results and set stringent limits on the existence of such exotic particle.
