Virasoro OPE and Conformal Blocks from the Inverse Shapovalov Form

Jean-François Fortin, Lorenzo Quintavalle, Witold Skiba

We derive expressions for the Virasoro OPE and four-point conformal blocks on the sphere via the resolution of identity recently determined in [Phys. Rev. D 111, 085010 (2025), arX…

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…

Kac-Moody Algebras on Soft Group Manifolds

Rutwig Campoamor-Stursberg, Alessio Marrani, Michel Rausch de Traubenberg

Within the so-called group geometric approach to (super)gravity and (super)string theories, any compact Lie group manifold $G_{c}$ can be smoothly deformed into a group manifold $G…

Vacuum configuration of winding superstrings from non-standard semiclassical quantization

Tommaso Canneti, Federico Castellani, Wolfgang Mück

Semiclassical quantization techniques are unreliable, if the magnitude of the quantum fluctuations becomes comparable with a classical background scale. This is the case, for examp…
