This interaction has both vector and axial vector components, which behave oppositely under improper Lorentz transformations.
This interaction has both vector and axial vector components, which behave oppositely under improper Lorentz transformations. By measuring the disparity in distribution between gamma ray and electron emissions in the decay of cobalt-60 to nickel-60, Chien-Shiung Wu experimentally showed that this interaction violates parity conservation. The mass of this interaction's gauge bosons is provided by the Higgs boson upon the symmetry breaking of this interaction's unification with (*) electromagnetism. The W and Z bosons are the force carriers for this interaction, which mediates beta decay. For 10 points, name this fundamental force that occurs at almost the same length scale as  but whose coupling constant is much smaller than  the strong force.
