| Abstract | The nature of dark matter is an unresolved question in particle physics, with the lack of candidates remaining one of the most intriguing mysteries of modern physics. It has been proposed that the triply singlet colour-flavour-spin $\textit{uuddss}$ state of six quarks (sexaquark) could be very tightly bound, possibly even stable or incredibly long-lived. Decays of $\varXi^0_b$ baryons have been identified as decay channels in which the sexaquark could be produced and influence the missing mass distribution in the decay. Here, we search for $\varXi^0_b (usb) \rightarrow 2 \varLambda^0 (uds) + K^+ + \bar{p} $ decays where the two $\varLambda^0 (uds)$ baryons in the final state have the same quark content as the sexaquark candidate. |
