ITMP Seminar "New probes of the string spectrum"

ITMP Seminar
31 октября 2023

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Nov 1, 18:00 (Moscow time). It will be organised via Zoom.

Speaker: Dr. Chrysoula Markou, University of Mons

Title: New probes of the string spectrum

Abstract: As is well known, the string spectrum comprises infinitely many states that can collectively be visualized along Regge trajectories of increasing mass and spin. Its massless and lightest levels, as well as certain higher spins including the leading Regge trajectory, have been the focus of past studies. In this talk, we will discuss new probes beyond the leading Regge, starting with the interactions of some of the lightest subleading massive spin-2 superstring states. We will then proceed to discuss a new way of organizing the string spectrum based on Howe duality, presented in recent work with Evgeny Skvortsov, which allows for a covariant method of excavating string states and their interactions by entire trajectories, rather than individually.

If you want to join the seminar please register here before 16:00, November 1 here.
