Neutrino helps explain antimatter?

The neutrinos produced in a nuclear reactor in China can change their flavor faster than normal. This result raises the hope that physicists will soon explain why the universe is full of matter instead of antimatter.

Neutrinos as well as antineutrinos have three forms: electron, moun and tau. In the process of moving in space, these particles can continuously transform from one state into another. This variability is measured by theta12, theta23 and theta13. However, until recently, only two parameters were measured. By June last year, the T2K lab in Japan had scored neutrinos that wanted to transform electron neutrinos, providing initial estimates for theta13.

Identifying the third parameter of the neutrino will help physicists soon
In answer to the question, why did the universe choose matter instead of antimatter?

However, Kam-Biu Luk, a professor at the University of California, Berkeley, said that the T2K observation itself is based on only two parameters, so it is difficult to determine the unique value of theta13.

The breakthrough came when physicists at the Daya Bay Nuclear Reactor in southern China claimed to have identified theta13. They tracked anti-neutrinos by six reactors in Daya Bay and the results were announced at the Beijing Institute of Energy Physics on March 8, NewScientist. "Finally we know the size of theta13, it's not as small as we think ," Luk said.

The impact of this finding is enormous, says physicist Francis Halzen of the University of Wisconsin-Madison. Now researchers will be able to conduct experiments to find out if neutrinos are behaving differently from anti-neutrinos. From there, they could find clues to explain why the universe was leaning toward matter, rather than antimatter in the post-Big Bang era.
