"Reminiscences of the Standard Model" - Special Colloquium by Steven Weinberg

October 17, 2017 by Steven Weinberg

Abstract: "I will describe the path that led me to the electroweak theory of Salam and myself, and what happened afterwards"
Steven Weinberg is a theoretical physicist who holds the Josey Regental Chair in Science at the University of Texas at Austin. Together with Abdus Salam and Sheldon Glashow he was awarded the 1979 Nobel Prize in Physics for contributions to the theory of the unified weak and electromagnetic interaction between elementary particles, including, inter alia, the prediction of the weak neutral current. Weinberg’s research has extended over many areas of theoretical physics, especially in the theory of elementary particles and in cosmology. In recent years, he has been concerned with the fundamentals of quantum mechanics, and in particular whether any viable generalization of quantum mechanics is possible. He recently showed that existing observations of atomic clocks set stringent limits on the terms in the Lindblad equation for the density matrix representing departures from ordinary quantum mechanics. He has also returned to his concern with cosmology, working with Raphael Flauger on a new project: to evaluate the effects of intervening matter on gravitational radiation from distant sources, such as gravitational waves from coalescing black holes discovered by the LIGO observatory and from quantum fluctuations in the early universe.
