Yang-Baxter Deformations of the $Ad{S}_5\times S^5$ Pure Spinor Superstring

We present an integrable deformation of the $Ad{S}_5\times S^5$ pure spinor action based on homological perturbation theory. Its equations of motion, Lax connection and BRST symmetry are discussed. The resulting model describes a pure spinor superstring in a generalized supergravity background.
