32. From Parity Violation to the Standard Model and Beyond

Prof. Ming-Xing Luo (CSRC)

Plenary Talk

This talk reviews the historical path from the proposal of parity nonconservation to the establishment of the Standard Model. We trace the development from parity-violation experiments and the V–A theory through current algebra, flavor mixing, CP violation to the electroweak theory and beyond. This evolution illustrates how this brave challenge to a fundamental symmetry reshaped the field of...

19. The battle of symmetry vs asymmetry

John Donoghue (University of Massachusetts, Amherst)

Plenary Talk

The discovery of parity violation introduced asymmetry directly into our most fundamental laws. I will discuss how the conflict between symmetry and asymmetry has shaped where we are in fundamental physics and where we are going. Along the way we will check in on the discrete symmetries, the arrow of time and causality, work by T. D. Lee and G.C. Wick, Starobinsky inflation, etc..
