Another possibility is that the number of neutrinos has been considerably underestimated if the chemical potential has the opposite sign for all massive particles, including for each flavour a pair of neutrinos and antineutrinos. This physical circumstance gives a possibility of interpreting the generation of strong particle--antiparticle asymmetry in the universe, including for neutrinos.
In this case, if the particle really acts as its own antimatter, the antineutrinos will cancel each other out and make up a "neutrinoless" decay, with only 2.5 megaelectronvolts of energy spike, which is less than a thousandth of a billionth of a joule.

In 1955, as a chlorine-containing medium trapping the neutrino [v.sub.e], he used a container with a volume much more than 3.78 [m.sup.3] filled with carbon tetrachloride and located near the nuclear power reactor at the US object in the Savannah River Site area [19], However, in these neutrino [v.sub.e] detection schemes, the final result for scientists turned out to be negative for the reason that antineutrinos [v.sup.~.sub.e] appeared in the nuclear reactors used, and experimental setup of R.
These jets might be made of neutrons that undergo beta decay to form protons, electrons and antineutrinos.
Analyzing more than 300,000 electron antineutrinos (the antimatter counterpart of the electron neutrino) collected from the Daya Bay nuclear reactors during 217 days of operation, researchers found 6 percent fewer of the particles than predicted by the standard particle physics model.
I cannot say with the same empirical certainty that for every weak graduate from institutional africology there is a correspondingly strong one, as physicists can do regarding matter and antimatter, electrons and positrons, protons and antiprotons, quarks and anti-quarks, neutrinos and antineutrinos, and so on.
Taking into account that for each degenerate species only a fraction T/TF effectively contributes to the cooling rate and that there are one such initial species and two such final species, finally we arrive at the spectral flux of the UHE antineutrinos:
If neutrinos and their antimatter equivalent, antineutrinos, oscillate differently, this could provide the explanation.
A unique feature of SN1987A was the detection of a neutrino burst when two neutrino observatories, Kamiokande II and IMB, detected 11 and 8 antineutrinos respectively and this event arguably led to the beginning of neutrino astronomy.
