The decay of polarized versions of these particles are used to explain the left-right asymmetry of t
The decay of polarized versions of these particles are used to explain the left-right asymmetry of theweak interaction in the TWIST experiment. They're not electrons, but their anomalous g-factor cannot beexplained by QED, a fact used as evidence for non-Standard Model effects. These particles decay into apositron, an electron neutrino, and namesake antineutrino with lifetime of about 2.2 microseconds, andwere initially confused for pions after their prediction by Yukawa. Replacing the electron in hydrogen withone of these can catalyze room-temperature fusion because they are 207 times more massive than theelectron. On earth, they mostly come from cosmic rays. For 10 points, name this negatively-chargedspin-one-half elementary particle.
