What's the difference between an antineutrino and a positron?

Question

I'm confused

Answer 1

An antineutrino is the neutrino's antiparticle.  It has no charge and is theoretically massless.

A positron is an electron's anti-particle, but it's called a positron instead of an "anti-electron."  It has a charge of +1 and has the same mass as an electron.

Answer 2

in physics there is a thing call the standard model. this model explains all known fundamental particles.

these are:

up quark (+2/3)

down quark (-1/3)

charm quark (+2/3)

strange quark (-1/3)

top quark (+2/3)

bottom quark (-1/3)

electron (-1)

muon (-1)

tau (-1)

electron neutrino (0)

muon neutrino (0)

tau neutrino (0)

photon (0)

gluon (0)

W-/W+/Z bosons (-1/+1/0, respectively)

the numbers next to the particles represent their charges. notice how the charm quark has the same charge as an up quark. it is heavier, and is called a second generation quark, the same goes for strange quarks. top and bottom are third generation. electrons are part of a family of particles called leptons, as are neutrinos. muon and muon neutrinos are second generation, tau and tau neutrinos are third.

whenever you deal with just the word neutrino, it is most likely going to be an electron neutrino because it is the most common and the lightest. neutrinos have a mass so light that we cant even detect it. we just know that it has some mass, we dont know what it is.

each of those particles that i listed has an antiparticle. antiparticles have the opposite charge of its normal particle, but the same mass and the same all other properties.

the positron is the antiparticle that corresponds to the electron. so it has a +1 charge, and the same mass as the electron.

the antineutrino is the same mass as the electron neutrino (most likely, it could be the muon or tau neutrino), and has the same charge since the neutrino has a neutral charge. the opposite of neutral is still neutral. instead, physicists give another property to particles, called left or right handedness. neutrinos are right handed, antineutrinos are left handed.
