Search for Dark Matter in Upsilon Decays at BABAR Experiment
Abstract
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 $\Upsilon(4S) \to \Lambda \bar{\Lambda}$. Based on a data sample of $\Upsilon(2S)$ and $\Upsilon(3S)$ decays collected by the BABAR Experiment we report the most recent results and set stringent limits on the existence of such exotic particle.
