Neutrino - Wikipedia

WebHandedness refers to two properties of a particle: the direction of its spin and how it relates to the direction the particle is traveling. If you curl your hands into fists and extend your thumbs toward one another, you’ll see examples of right-handed and left-handed particles. WebA neutrino (/ nj uː ˈ t r iː n oʊ / new-TREE-noh; denoted by the Greek letter ν) is a fermion (an elementary particle with spin of 1 / 2) that interacts only via the weak interaction 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 rest mass of the neutrino is … cummings memorial https://instrumentalsafety.com
