full_question: A discovery involving its parity was awarded the first Wolf Prize in Physics, and was identified in an experiment in which Wú Jiànxióng cooled a cobalt isotope using adiabatic demagnetization. This interaction can be classified using Wolfenstein parameters as part of an analysis using CKM matrices. Cronin and Fitch showed that it violates CP symmetry by analyzing neutral kaons that decayed into antiparticles. The electromagnetic force was unified with, for 10 points, what fundamental force that causes beta decay?
