1-loop renormalisability of integrable sigma-models from 4d Chern-Simons theory
Sylvain Lacroix, Nat Levine, Anders Wallberg
Large families of integrable 2d sigma-models have been constructed at the classical level, partly motivated by the utility of integrability on the string worldsheet. It is natural…

Demystifying integrable QFTs in AdS: No-go theorems for higher-spin charges
António Antunes, Nat Levine, Marco Meineri
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…
