ITMP Seminar "Towards the Virasoro-Shapiro Amplitude in AdS5xS5"

ITMP Seminar
22 марта 2021

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Mar 24, at 18:00 (Moscow time). The seminar will be arranged via Zoom.

 

Speaker: prof. Paul Heslop, Durham University

Title: Towards the Virasoro-Shapiro Amplitude in AdS5xS5

Abstract: We propose a systematic procedure for obtaining all single trace 1/2-BPS correlators in N=4 super Yang-Mills corresponding to the four-point tree-level amplitude for type IIB string theory in AdS5xS5. The underlying idea is to compute generalised contact Witten diagrams coming from a 10d effective field theory on AdS5xS5 whose coefficients are fixed by the flat space Virasoro-Shapiro amplitude up to ambiguities related to commutators of the 10d covariant derivatives which require additional information such as localisation. We illustrate this procedure by computing stringy corrections to the supergravity prediction for all single trace 1/2-BPS correlators up to O(α′7), and spell out a general algorithm for extending this to any order in α′.

 

If you want to join the seminar please register here before 14:00, March 24.
