Dibaryons and where to find them

Abstract

In recent years there has been tremendous progress in the investigation of bound systems of quarks with multiplicities beyond the more usual two- and three-quark systems. Experimental and theoretical progress has been made in the four-, five- and even six-quark sectors. In this paper, we review the possible lightest six-quark states using a simple ansatz based on SU(3) symmetry and evaluate the most promising decay branches. The work will be useful to help focus future experimental searches in this six-quark sector.

“…Furthermore, the discovery of heavier strange d* states (d s *, d ss * and d sss * ) [28] in the predicted SU(3) decuplet would be further evidence of its hexaquark origin and cement its role in hadron and astrophysics with all the impacts discussed previously. Such states could potentially play a role in the dynamics of strange matter analogous to the d* for light quark matter (e.g.…”
