[3][4][5] There is a theory that strange particles such as hyperons[6] and dibaryons[7][8] could form in the interior of a neutron star, changing its mass–radius ratio in ways that might be detectable.
Accordingly, measurements of neutron stars could set constraints on possible dibaryon properties.
These dibaryons would very quickly dissolve into quark–gluon plasma during the collapse, or go into some currently unknown state of matter.
[13][14][15] The study found that production of stable d*(2380) hexaquarks could account for 85% of the Universe's dark matter.
[16][17] In 1977, Robert Jaffe proposed that a possibly stable H dibaryon with the quark composition udsuds could notionally result from the combination of two uds hyperons.
