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 characterised by being neutral, compactly bound, and cosmologically stable within certain mass limits; unique properties that make it a compelling dark matter candidate.

Despite its elusive nature, several experimental collaborations have been searching for evidence of its existence. In particular, this contribution presents an update on its ongoing search 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 heavy-ion collisions (Pb-Pb) during LHC Run 2.
