What is the difference between a photon and a neutrino? Why are they not considered photons?

Answer 1

Photons are bosons. Neutrinos are fermions,

Since the electromagnetic interaction has an infinite range, photons are gauge bosons, and since neutrinos are matter particles similar to electrons, the photon is more akin to a W because both are bosons.

Answer 2

A photon is a boson, a neutrino is a fermion and also a lepton. So they are completely different particles.

A photon is a boson, which means that it has zero charge and spin of one. It is also its own anti-particle and the quanta of the electromagnetic field. It has zero mass, which means that it has to move at the speed of light.

A neutrino is a lepton, which means that it does not interact through the strong force, and it is a fermion, which means that it obeys the Fermi-Dirac statistics.

Together with the muon and tauon, which are its heavier generation particles, the electron is also a fermion. Three generations of neutrinos—the electron neutrino, the muon neutrino, and the tauon neutrino—have a spin of 1/2, no charge, and an anti-neutrino antiparticle for each.

Electron neutrinos are emitted in radioactive beta decay and carry away some of the energy released. In beta decay a neutron decays into a proton, an electron and an electron antineutrino. #n^0 rarr p^++e^(-)+ bar nu_e^0# Neutrinos are thought to have zero mass and travel at the speed of light. They rarely interact with other particles of matter. This is still open to debate. It is also thought that neutrinos oscillate between the electron, muon and tauon particles.

Answer 3

While both photons and neutrinos are fundamental particles, they differ in their properties, interactions, and roles in the universe. Photons are elementary particles that carry electromagnetic radiation, including light; they have zero rest mass and travel at the speed of light. On the other hand, neutrinos are elementary particles with tiny masses and no electric charge; they interact with other matter only weakly, making them very difficult to detect.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
