50 years of discoveries of neutral currents and asymptotic freedom






The year 1973 brought two major discoveries, one experimental and one theoretical, which set the stage for the formulation of Standard Model and lead to further discoveries confirming the basic ideas on which it is based - quarks and leptons as fundamental particles interacting via intermediate vector bosons - and culminating with Higgs boson discovery in 2012. While the discovery of neutral currents was to some extent expected, the discovery of asymptotic freedom of nonabelian gauge theories came as complete surprise to all theorists. I will recall both discoveries, but focus on the second as it brings important lesson for current situation in particle physics.
