We are pleased to announce that the next ITMP seminar will be held on Wednesday, Nov 11, at 18:00. The seminar will be arranged via Zoom.
Speaker: Alexander Zhiboedov, CERN
Title: Event shapes, the light-ray OPE and superconvergence
Abstract: I will describe recent progress in understanding event shapes in conformal field theories. Familiar from the description of hadronic events at colliders, these observables are computed by matrix elements of the so-called light-ray operators. Characterizing the light-ray operators in a nonperturbative setting poses many theoretical challenges. I will describe some of the recently developed tools to perform computations of conformal event shapes and illustrate them using N=4 SYM. Finally, I will explain how via holography some of the basic properties of conformal event shapes lead to nontrivial sum rules obeyed by possible UV completions of general relativity.
If you want to join the seminar please register here before 14:00, November 11.
