Quantum corrections to $Ad{S}_5\times S^5$ left-invariant superstring current algebra

Dáfni F. Z. Marchioro, Daniel Luiz Nedel

In this work the pure spinor formulation of the superstring is used to study quantum corrections to the left current OPE algebra of the coset $PSU(2,2|4)/SO(4,1)\times SO(5)$ si…
