"Neutrinos" and "anti-neutrinos" Unidentified difference in properties May 4, 7:54

Japan is central to the fact that there is a possibility that there is an unidentified difference in properties between "neutrinos," one of the elementary particles that make up a substance, and its anti-neutrino pair. I found out by the experiment of the international research group. Experts say, "It needs further verification, but it may lead to the elucidation of the origin of the universe."

Neutrinos, one of the elementary particles that make up matter, have antimatter and antineutrinos that rotate in opposite directions and form a pair as reflected in the mirror, but only matter exists in the present universe. From this, it is predicted that there may be differences in properties that have not been confirmed so far, and an international research group led by Japan is conducting experiments.

In the experiment, neutrinos and anti-neutrinos were launched to the experimental facility "Super-Kamiokande" in Gifu prefecture, which is about 300 km away from the experimental facility in Ibaraki prefecture, and a phenomenon called "neutrino oscillation" was observed.

As a result of summarizing the results in the middle, the phenomenon called "neutrino oscillation" was caused by 90 neutrinos and 15 anti-neutrinos, and it was found that there is a possibility that there is a difference in properties. .

Professor Yoshihito Asai of the University of Tokyo, who specializes in elementary particle physics, says, "We can't say yet, we need to collect more data and verify it, but it may lead to the elucidation of the origin of the universe."
