Sexaquark Search in ALICE — •Andrés Bórquez for the ALICE Germany collaboration — Heidelberg University

In 2017, G. Farrar proposed the sexaquark, a hypothetical six-quark state with the quark content uuddss. This particle is characterized by being neutral, compactly bound, and cosmologically stable within certain mass limits. These unique properties make it a compelling dark matter candidate.

Despite its elusive nature, several experimental collaborations have searched for evidence of its existence. This contribution presents an update on the ongoing search for the sexaquark within the ALICE experiment at the LHC. The strategy focuses on identifying displaced strangeness production caused by the annihilation of anti-sexaquarks with detector material following their potential production in Pb-Pb collisions during LHC Run 2.
