Do hexaquarks exist?

At the moment, hexaquarks are only hypothetical particles.


A hexaquark was possibly observed at the Jülich Research Center in 2014[1], but it was not confirmed.

It is thought that if hexaquarks do exist, they would be quite stable[2][3], and might possibly account for much of the dark matter in the universe[3].
