Bounds on the next-to-leading Wilson coefficient in maximal supergravity
Abstract
One expects type II string theory to be the unique ultraviolet completion of maximal supergravity. Motivated by the recent computation of the unitary bound on the leading Wilson coefficient within the S-matrix bootstrap, we analyse the minimum of the next-to-leading Wilson coefficient in string theory in seven spacetime dimensions. We find that the next-to-leading Wilson coefficient is minimum at the same point as the leading Wilson coefficient.
