## Upcoming Events

For string backgrounds with known exact worldsheet theory descriptions, ordinary string perturbation theory can be employed to study their observables such as string spectrum and scattering.

Should we include a sum over wormhole topologies in the path integral of quantum gravity?

Klaas Parmentier will give the Stanford Institute for Theoretical Physics Monday Colloquium on November 4, 2024.

Jeongwan Haah will be giving the Stanford Institute for Theoretical Physics Monday Colloquium on November 11, 2024.

Sahand Seifnashri from the Institute for Advanced Study, Princeton will be giving the Stanford Institute for Theoretical Physics Monday Colloquium on November 18, 2024.

Non-perturbative effects in string theory, such as D-branes, play an essential role in our current understanding of both quantum gravity and string-based models of the universe.

In this talk I will do three things. First, I will outline the conditions under which the interaction rate of inelastic processes with a system consisting of N targets scales as N^2.
