Myonnøytrino
Myonnøytrino refers to one of the three known types, or "flavors," of neutrinos. Neutrinos are fundamental subatomic particles that are electrically neutral and have a very small mass. They interact very weakly with other matter, making them notoriously difficult to detect. The three flavors are the electron neutrino, the muon neutrino, and the tau neutrino. The myonnøytrino is the neutrino associated with the muon, analogous to how the electron neutrino is associated with the electron. When a muon is produced in a particle interaction, a myonnøytrino (or its antiparticle, the antimuon neutrino) is also produced.
The existence of different neutrino flavors was first suggested by experiments involving muons. Over time, it
