Scientists have been studying about the neutrinos for the last three to four years and found that the particles oscillate over a distance of 500 miles. Now, the scientists have announced a new result at the Neutrino 2018 conference which was held in Germany’s Heidelberg. As pert the new result, scientists have detected strong evidence of muon antineutrinos oscillating into electron antineutrinos. Such phenomenon has never been observed before.
NOvA is the world’s largest-baseline neutrino experiment located at the U.S. Department of Energy’s Fermi National Accelerator Laboratory. This experiment is for detecting more about the Neutrinos. This particle moves through matter, but it is quite impossible to detect. It studies the process how neutrinos and antineutrinos change from one type to another. From example muon to tau. If scientists can observe the changes of neutrinos and antineutrinos, they can know the particles important in the formation of the universe.
The experiment works on two particle detectors, one is at Fermilab in Illinois, and another one is at northern Minnesota. The latest result is derived from NOvA’s first run. The study was started in February 2017.
Peter Shanahan, co-spokesperson of the NOvA collaboration stated that antineutrinos are quite difficult to make than neutrinos and quite impossible to find by the detector. The antineutrinos are called as oscillate. Japan’s T2K experiment in 2017 informed that it had detected hints of this phenomenon. Now, both T2K and NOvA are working together to find out more result shortly.
Jim Siegrist, Associate Director for High Energy Physics, Department of Energy Office of Science informed that the first result had helped Nova to move one step ahead, i.e., to the second phase of the experiment. Scientists will continue their study about antineutrinos in 2019 also and will try to gather sufficient amount of data about neutrinos and antineutrinos.
