Question

what are neutrino and antineutrinos?

Answer 1

1) Neutrino : An elementary particle with zero charge and a very small mass; there are three known neutrinos, the electron, mu and tau.

2) Antineutrinos : The antiparticle of a neutrino.

Answer 2

Answer:

HI MATE.

NEUTRINO :

A neutrino is a fermion that interacts only via the weak subatomic force and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small that it was long thought to be zero. The mass of the neutrino is much smaller than that of the other known elementary particles.

They're important to our understanding of the kind of processes that go on in the sun, and also an important building block for the blueprint of nature,” Hooper said. Particle physicists originally believed that neutrinos were massless.They're tough to detect since they interact so weakly with other particles.

ANTINEUTRINOS :

Antineutrinos are the antiparticles of neutrinos. The antineutrino is an elementary subatomic particle with infinitesimal mass (less than 0.3eV..?) and with no electric charge. Neutrinos and antineutrinos belong to the family of leptons, which means they do not interact via strong nuclear force.

The antineutrino discovered by Cowan and Reines is the antiparticle of the electron neutrino.

DIFFERENCE BETWEEN THEM :

An antineutrino is the antiparticle partner of the neutrino, meaning that the antineutrino has the same mass but opposite “charge” of the neutrino. Although neutrinos are electromagnetically neutral (they have no electric charge and no magnetic moment), they may carry another kind of charge: lepton number.

Hope it helps you mate.
