A new theory suggests that dark matter might not be made of undiscovered, never-before-seen particles. Instead, researchers write, it might be made from a type of "hexaquark" detected in 2014.

This is the second report from space.com on this topic, others I see reporting too but I note this in today's report. "These BECs might have formed soon after the Big Bang, as space transitioned from a sea of hot quark-gluon plasma with no distinct atomic particles into our modern era with particles like protons, neutrons and their cousins. At the moment when those basic atomic particles formed, conditions were perfect for hexaquark BECs to precipitate from the quark-gluon plasma. "Before this transition, the temperature is too high; after it, the density is too low," Bashkanov said. During this transition period, the quarks could have frozen into either ordinary particles, such as protons and neutrons, or into the hexaquark BECs that today might make up dark matter,"

Looks like some fine tuning here in the math to explain BECs and keep them stable. There is the missing primordial neutrinos created in the Big Bang model too, not directly detected yet. The critical timeline from the Planck time until 3 minutes or so after the BB event is a very busy place in cosmology :). Other contenders for dark matter are reported like axions or WIMPS, etc.
