The Bootstrap Siege of M-theory

Andrea Guerrieri
(City University )
Abstract
In recent years, analytic and numerical Bootstrap methods have emerged as powerful tools to probe non-perturbative aspects of quantum field theory and quantum gravity. In this talk I will discuss the nonperturbative S-matrix Bootstrap approach to scattering amplitudes in maximal supergravity. After a brief overview of the method, I will review earlier results obtained in this framework, including bounds on the Wilson coefficient of the R^4 operator in D=9,10,11, and the observation that string and M-theory amplitudes appear to lie on the boundary of the allowed bootstrap region. I will then present preliminary results for the higher dimensional corrections like the D^4 R^4 interaction in eleven dimensions and show how the resulting constraints on the non-perturbative M-theory scattering amplitude match expectations from string/M-theory.
