The new dark matter candidate: D-star hexaquark

Researchers have identified a quantum particle that may be related to the production of dark matter at the beginning of the universe.

Dark matter is a great mystery. We know that there is much more dark matter than regular matter in the universe, but we still don’t know what it is made of. However, a recent study at the University of York points to a possible candidate: a subatomic particle called the d-star hexaquark.

What is dark matter?

All matter within a galaxy orbits around the center due to its gravitational attraction. By studying the motion of stars and gas, you can know how much matter there is in a galaxy.

Surprisingly, what is observed is that the speed of stars and the interstellar medium within galaxies is much greater than expected based on the visible matter in them. This means that there must be more matter in the galaxies than we can observe.

This mass that we cannot detect in any region of the electromagnetic spectrum is called dark matter. In the Milky Way, dark matter is 10 times more abundant than matter in the form of stars and gas and is concentrated in a halo that extends far beyond the disk.

The discovery

Scientists at the University of York recently discovered a particle, consisting of six quarks, which they called the d-star hexaquark.

The researchers suggest that after the Big Bang, the d-star hexaquark may have grouped to form the Bose-Einstein condensate – the fifth known state of matter, and this d-star hexaquark condensate would be what constitutes dark matter.

Recently Professor Daniel Watts and Dr. MIkhail Bashkanov published an article about the plausibility of the theory. According to Professor Daniel Watts, we now have a clue to one of the biggest questions in science: the origin of dark matter.

According to him, calculations indicate that d-star condensates may, in fact, be dark matter. Dr. Mikhail Bashkanov adds that the next step is to study how the d-stars interact, more precisely when they attract and repel each other.

In addition, he says that new measures are already being put in place to study how d-stars behave inside an atomic nucleus.

Now, we have to wait for the next results and maybe we will have the definitive answer to one of the most intriguing questions in science.
