IAS Amplitudes Group Meeting

Abstract: String spectra comprise infinitely many physical states of arbitrarily high mass and spin, the presence of all of which is crucial to the good UV behaviour of string scattering amplitudes. Yet what do all these states look like? In this seminar, we will discuss a new, covariant and efficient technology of constructing entire string trajectories deeper in the open string spectrum, as well as work to appear on the closed string and possibly other work in progress on string amplitudes and the modelling of Hawking radiation in string theory. The aim of this direction is to attempt to shed light on aspects of the underlying nature of string theory per se.
