A number of experiments have been suggested to detect dibaryon decays and interactions. Several candidate dibaryon decays were observed but not confirmed in the 1990s.
There is a theory that strange particles such as hyperons and dibaryons could form in the interior of a neutron star, changing its mass–radius ratio in ways that might be detectable. Conversely, measurements of neutron stars set constraints on possible dibaryon properties. Large fraction of neutrons could turn into hyperons and merge into dibaryons during the early part of a neutron star to black hole collapse. These dibaryons would very quickly dissolve into quark–gluon plasma during the collapse, or go into some currently unknown state of matter.
