50 years with the GIM mechanism
Antonio Davide Polosa
The title of this article is taken from the name of the conference that should have been held in Rome, at Sapienza University, in April 2020, canceled due to the health emergency. We intended to make a written report of what we learned directly from the protagonists of the discovery whose 50th anniversary occurs this year. While waiting to reorganize the event in 2021, we offer the reader a brief illustration, for non- specialists, of the GIM mechanism, from the famous result of Sheldon Glashow, John Iliopoulos and Luciano Maiani.
