Integrable Deformation of the AdS 5 × S 5 Superstring Action

An integrable deformation of the type IIB ${\mathrm{AdS}}_{5}\ifmmode\times\else\texttimes\fi{}{\mathrm{S}}^{5}$ superstring action is presented. The deformed field equations, Lax connection, and $\ensuremath{\kappa}$-symmetry transformations are given. The original $\mathfrak{psu}(2,2|4)$ symmetry ... View More
