Scientists say d-star hexaquarks may have formed dark matter after the Big Bang.
A candidate particle for dark matter has been discovered by scientists, with researchers suggesting a d-star heaxaquark is another target in the bid to solve one of the universe's biggest mysteries.
Traditionally, protons and neutrons are made of three quarks each. Over recent years, scientists have found exotic particles that are made of four or five quarks, known as tetraquarks and pentaquarks. They discovered the particle during experiments at the Juelich accelerator in Germany, in which they were smashing proton beams on neutrons. At some energy, they found a new particle was produced. They are currently carrying out more experiments in an attempt to study the internal structure of the d-star hexaquark.
"So we have motive and opportunity ," Bashkanov said."What we do not yet know is capability: we do not know yet if the interaction between hexaquarks permit them to form condensate of desired properties. We are currently working on this question."
