ROCHESTER/STONY BROOK (US)# Scientists have announced the first definitive observation of the transformation of muon neutrinos to electron neutrinos#a type of neutrino oscillation that had never been observed.#
#This discovery of electron neutrino appearance from muon neutrinos by the T2k experiment opens another critical door in our journey to unveil the secrets of our universe.#
The probability that random statistical fluctuations alone would produce the observed excess of electron neutrinos is less than one in a trillion.
An analysis of the data from the Super-Kamiokande detector associated with the neutrino beam time from J-PARC reveals that there are more electron neutrinos (a total of 28 events) than would be expected (4. 6 events) without this new process.
