On the other hand,
if the electron neutrinos contain the heaviest masses, then the additional Earth - induced mass would make them mix less with those of the other two neutrino flavors.
Not exact matches
But
if they are within 100,000 times or so the mass of normal
neutrinos — or a few thousand
electron volts — most should still exist, with some occasionally decaying into lighter
neutrinos and X-ray photons.
The sun was thought to produce
electron neutrinos only, and
if these particles were somehow morphing into the other two flavours as they travelled through space, it could explain the anomaly.
If the
neutrinos encounter a plasma wave, interactions between the
neutrinos and the
electrons can cause the wave to grow rapidly.
«
If all that energy goes to the
electrons, then none is left for
neutrinos,» Radford said.
This energy is used to distinguish
if the original
electrons were generated via a process that releases two
neutrinos or no
neutrinos.
In the paper, Glashow and Cohen point out that
if neutrinos can travel faster than light, then when they do so they should sometimes radiate an
electron paired with its antimatter equivalent — a positron — through a process called Cerenkov radiation, which is analogous to a sonic boom.
So rather than, say, a 10 percent chance of an
electron neutrino turning into a muon
neutrino, for example, physicists wonder
if the odds are lower that an
electron antineutrino turns into a muon antineutrino.
Physicists are not sure
if the greatest, or heaviest, of the three masses is most likely to be an
electron neutrino or least likely to be an
electron neutrino.
On the very, very rare occasion that a
neutrino interacts with another particle,
if the reaction appears to produce an
electron, then the
neutrino was an
electron flavor in its final moments;
if it produces a muon, the
neutrino was muon - flavored.
There are three known varieties of
neutrinos —
electron neutrinos, muon
neutrinos and tau
neutrinos — which are thought to have very small masses,
if they have any mass at all.
In order to see
if oscillation has occurred during the
neutrinos» 500 - mile journey, the detector at Minnesota measures the relative fraction of mu and
electron neutrinos.
«Similarly,
if oscillations did not occur, scientists expected to see only one
electron neutrino appearance (due to background interactions).
