On Wednesday, the team announced that six of the muon neutrinos that started off at J - PARC appear to have transformed into
electron neutrinos before reaching Super-Kamiokande, where they were detected.
So in the very early Universe, some 17 keV neutrinos could have been transformed into
electron neutrinos before they could decay, adding to the pressure of the big bang.
Not exact matches
The laws of physics may permit a
neutrino with a mass to change from one type into another, so
electron neutrinos may simply transform themselves into undetectable muon or tau
neutrinos before they fly across the 150 million kilometres of space between the Sun and the Earth.
For example,
electron neutrinos born in the sun morph into other flavors
before they reach Earth, so that fewer
electron neutrinos arrive than would otherwise be expected.
Near the end of Professor Davis» life, a large team of researchers (~ 178 coauthors) reported that solar
electron neutrinos oscillate away
before they reach our detectors.
