#antineutrino

• Antineutrino — The antiparticle corresponding to a neutrino; an electrically neutral lepton with an extremely small (or zero) rest mass and half-integer spin, typically emitted during beta-minus decay processes of atomic nuclei. In a structural sense, it possesses an opposite helicity (right-handed) compared to that of the neutrino (left-handed) and interacts extremely weakly with matter.
• Antineutrino — The antiparticle corresponding to the neutrino, characterized by an extremely small (nearly zero) mass, a neutral electric charge, and half-integer spin, possessing an opposite helicity (right-handed) compared to that of the neutrino. This subatomic entity is predominantly emitted during beta-minus decay processes, interacting with matter exclusively through the weak nuclear force and gravity, which makes it extremely difficult to detect.
