Centre for Particle Theory Colloquia: Scattering Amplitudes in String Theory and Field Theory

Presented by Michael Green, Cambridge

1 February 2011 16:15 in CLC 202

String theory provides an ultraviolet complete extension of Yang-Mills theory and general relativity.  This talk will describe the structure of scattering amplitudes in string theory and contrast them with corresponding field theory amplitudes.  The talk will focus in particular on the structure of graviton scattering which has a rich perturbative and non-perturbative structure that is strongly constrained by "duality" symmetries.  This provide an intriguing insight into the ultraviolet divergences of the corresponding (super)gravity field theory.
