Although E. C. George Sudarshan and Robert Marshak developed the theory nearly simultaneously, Feynman's collaboration with Murray Gell-Mann was seen as seminal because the weak interaction was neatly described by the vector and axial currents. Source: Internet

At distances around 10 −18 meters, the weak interaction has a strength of a similar magnitude to the electromagnetic force, but this starts to decrease exponentially with increasing distance. Source: Internet

For example, a neutral pion (which decays electromagnetically) has a life of about 10 −16 seconds, while a charged pion (which decays through the weak interaction) lives about 10 −8 seconds, a hundred million times longer. Source: Internet
