Toughest trial of Weak Interaction
Abstract: How the riddle of beta decay was solved by Fermi? How weak interaction appeared in the realm of modern physics? Why weak interaction faced series of amendments and how the problem was solved? I would try to find answer to these questions . It has been more than eighty years since Enrico Fermi informed the world that there exists a weak interaction by his famous nuclear beta decay theory, yet its importance has not faded. Various changes and modifications have been made to Fermi’s weak interaction theory during the process of formulation of Standard Model but still the fundamental idea of Fermi serves as a core part of this model. Now it is known that not only beta decay, most of the elementary particles such as muons, kaons, pions and hyperons decay via weak interaction. Years of Conundrum By the end of 1920, it was evident that there was something strange about beta decay. Alpha and gamma rays, which were also the nuclear byproduct like beta rays, had...
