Scientists have discovered a new elementary particle that may be the very dark matter. Thus, hexaquart D* can answer one of the greatest mysteries. After all, dark matter consists of about a quarter of the Universe, reports the Chronicle.info with reference to the Apostrophe.

Scientists suspect dark energy in performing the role of driving force in the expansion of the Universe. And it accounts for 68% of all things. The remaining 5% is the visible world, which includes all stars, planets and galaxies. Scientists know about the existence of dark matter through the gravitational force that it affects the visible world. It is believed that without dark matter, galaxies would just split up.

But since it does not emit or absorb light, it cannot be seen. Scientists do not know what she is really. Several elementary particles have now become candidates for the role of the very dark matter. Therefore, scientists are now conducting experiments using particle colliders to reduce the number of candidates.

In the new study, the researchers Bashkan Mikhail and Daniel watts of the University of York in the UK has put forward a new candidate, which could be dark matter.

“The matter around us consists of molecules, molecules consist of atoms, atoms – of the atomic nucleus, around which electrons whirl. Atomic nuclei are divided into protons and neutrons. Those, in turn, consist of quarks. Thus, quarks are the building blocks of matter”, — said the Bashkan.

Usually, protons and neutrons consist of three quarks. But in recent years scientists have discovered exotic elementary particles of four or five quarks. They are called tetraquarks and pentaquarks.

Hexaquart, which consists of six basic blocks, has also been recently opened. According to Bashkanova, it is composed only of light quarks.

“The fact that it is possible to form D*, if you push the protons and neutrons. We believe that this particle is very compact, despite the fact that contains six quarks in itself. She probably has the size of a proton, which consists of three quarks”, — said the scientist.

In his opinion, there are a number of reasons why D* can be dark matter. First, this particle really exists. Second, in the early Universe there were a lot of quarks with high density, which is similar to the conditions of laboratory experiments. Finally, scientists know that particles with bosons can form Bose-Einstein condensates, which are also considered candidates for the role of dark matter.

“So we have reason (hexaquart is bosons) and opportunity (high density of the early Universe)”, — said the Bashkan.

“But we don’t know anything about the abilities. We do not know whether the interaction between hexachrome to form a condensate with the desired properties. We are currently working on this issue”, — said the scientist.

According to him, still many questions need to answer. But nominated by him and his colleague the hypothesis is quite suitable for testing.
