In 1958, Gell-Mann in collaboration with Richard Feynman, in parallel with the independent team of E. C. George Sudarshan and Robert Marshak, discovered the chiral structures of the weak interaction of physics and developed the V-A theory (vector minus axial vector theory). This work followed the experimental discovery of the violation of parity by Chien-Shiung Wu, as suggested by Chen-Ning Yang and Tsung-Dao Lee, theoretically.
