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

The LOF can push the chiral nanoparticle sideways, in the direction relying on the helicity of the particle as well as the phase difference between two waves. Analytical theory reveals that the LOF comes … A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the two is called … See more The helicity of a particle is positive (“right-handed”) if the direction of its spin is the same as the direction of its motion. It is negative (“left-handed”) if the directions of spin and motion are opposite.
