If axions do managed to find it – the real scientific breakthrough
Physicists say they've found evidence of the existence of the elusive elementary particles axion, which can be part of the mysterious dark matter. Research project to study dark matter XENON1T, located in the underground laboratory of Gran Sasso in Italy may have just ushered in a new era in physics. As The New York Times, describing in detail a scientific experiment, an international team of scientists has established two tons of ultrapure liquid xenon in the tank under an Italian mountain. Xenon is a noble gas without color, taste and odor, which is extremely stable. Inertness makes it an ideal candidate for the detection of any particles that pass through it. Is it a new discovery – the real revolution in physics?
As the authors of the study in an official press release, they may have found evidence of a long-predicted type of subatomic particle, the axion. For the first time the existence of the axion was proposed in 1977 to explain the discrepancy in particle physics. Over time, the axions have also become a popular way to explain the existence of dark matter – the mysterious substance that constitutes 85 percent of the mass of the Universe. It is noteworthy that to date, there is no direct evidence of its existence.
In the experiment, XENON1T, the researchers found two tons of ultrapure liquid xenon in the tank under an Italian mountain. In search involving one hundred and fifty scientists who produce high-precision measurements of elementary particles colliding with each other. In a recent study, physicists have registered abnormally a lot of events that can be the evidence of the existence of new particles – solar axions, and new properties of neutrinos, what I in a previous article.
In the work, which has not yet passed peer review and on the website of Purdue University, the researchers write about the discovery of «amazing excess of events» interacting with the particles of xenon — these events cannot be explained using the standard model of physics. Let me remind you that according to scientists dark matter consists of particles, freely passing through the usual detectors (they don't have a strong sensitivity), but their total mass is large enough to grossly influence the matter through gravitational interaction.
Here are the search of the mysterious dark matter.
Gravitational interaction of elementary particles is the weakest of all fundamental interactions, which is characterized by the participation in the interaction of the gravitational field or gravitational field. Excess of the identified interactions at the time of this writing, has three explanations. According to the first, the most simple explanation, the reason for the huge number of events is contamination in the tank. The second possible explanation assumes that the excess events might be caused by neutrinos.
But a third explanation is the most daring and scientists may have serious implications for physics. As you probably guessed, it is the latter explanation assumes the existence of axions. If all do so, that is the first observation of an elusive sub-atomic particles. It should be noted – as he writes Futurist.com – that the existence of axions is not a direct explanation of dark matter, but the authors of the research believe that they could prepare the way for the creation of dark matter in the early stages of our Universe.
The Scientists, no doubt, excited the third possible explanation, although calling on the public to show restraint, as there are two other potential explanations. But what if the team XENON1T did find a hypothetical subatomic particle?

In an email to Live Science Chand Prescod-Weinstein, a physicist from the University of new Hampshire, who was not involved in the study, if confirmed, this will be the most significant discovery in physics since the discovery of cosmic acceleration.
However, to celebrate too early. The fact that from time to time the scientists are wrong – remember the story of the discovery of such a large black hole that its existence is not possible? After just a few months after the publication of the study, two independent teams of scientists have published the refutation, according to which detection . So we just need to wait for the results of the review study and try to learn about the mysterious dark matter as much as possible. Do you think this is a scientific breakthrough or a simple contamination of a VAT of xenon? Response
