ITMP Seminar "Demystifying integrable QFTs in AdS: No-go theorems for higher-spin charges"

Dear Colleagues,
We are pleased to announce that the next ITMP seminar will be held on Wednesday, Apr 9, 18:00 (Moscow time). It will be organised via Zoom.

Speaker: Dr. Nat Levine, University of Amsterdam

Title: Demystifying integrable QFTs in AdS: No-go theorems for higher-spin charges

Abstract: Higher-spin conserved currents and charges feature prominently in integrable 2d QFTs in flat space. Motivated by the question of integrable field theories in AdS space, we consider the consequences of higher-spin currents for QFTs in AdS_2. We find that their effect is much more constraining than in flat space. Specifically, it is impossible to preserve: (a) any higher-spin charges when deforming a massive free field by interactions, or (b) any spin-4 charges when deforming a CFT by a Virasoro primary. We therefore conclude in these settings that there are no integrable theories in AdS with higher-spin conserved charges.
