That is the query put forth in a brand new paper published Feb.12 in the Journal of Physics G. The authors outlined how dark matter could be the product of a particle referred to as the d*(2380) hexaquark, which was doubtless detected in 2014.
Dark matter, which exerts a gravitational pull, however, emits no mild, is not one thing anybody’s ever touched or seen. We do not know what it is manufactured from, and countless searches for the stuff have come up empty. However, an awesome majority of physicists are satisfied. It exists. The proof is plastered all around the universe: Clusters of stars spinning far quicker than they in any other case ought to, mysterious distortions of light throughout the evening sky, and even holes punched in our galaxy by an unseen impactor level to one thing being on the market — making up many of the mass of the universe — that we do not but perceive.
Most widely studied theories of dark matter contain entire courses of by no means-earlier than-seen particles from nicely exterior the Standard Model of physics, the dominant principle describing subatomic particles. Most of those match into one in every of two classes: the light-weight axions and the heavyweight WIMPs, or weakly interacting large particles. There are different, extra unique theories involving as-but undiscovered species of neutrinos or a theoretical class of microscopic black holes. However, not often does anybody suggest that darkish matter is manufactured from one thing we already know exists.
Quarks are basic physical particles within the Standard Model. Three of them sure collectively (utilizing particles often known as gluons) could make a proton or a neutron, the constructing blocks of atoms. Prepare them in different methods, and also you get totally different, more exotic particles. The d-star is a positively charged, six-quark particle that researchers consider existed for a sliver of a second throughout a 2014 experiment at Germany’s Jülich Research Center. As a result of it was so fleeting that d-star detection hasn’t been completely confirmed.
Particular person d-stars could not clarify the dark matter as a result of they do not final lengthy sufficient earlier than decaying. Nevertheless, Bashkanov informed Live Science, early within the universe’s history, the particles might need to be clumped collectively in a means that may have stored them from decaying.
