Sommaire:

We study dual strong coupling description of an integrable deformation of the $OSp(N|2m)$ sigma model. This description is based on the set of screening charges, which we present and which describes the integrable structure of this theory. We find one-parametric Yang-Baxter deformation of the $OSp(N|2m)$ sigma model and study its one-loop renormalization group flow. This action is conjectured to appear from the mentioned system of the screening charges.
