Particles and Fields at the LHC

Speaker: 
George Sterman (Yang Institute for Theoretical Physics, Stony Brook, USA)
Abstract: 
This talk will review how high energy experiments reveal quantum fields, using as a prime example the theory of the strong interactions, quantum chromodynamics. We'll review the classical concept of gauge theories and the quantum consequence of asymptotic freedom, with the goal of illustrating how the complex outcomes of particle collisions have been used to confirm simple underlying laws.
