Classical spectral curve of the AdS5 × S5 lambda superstring
Classical spectral curve of the AdS5 × S5 lambda superstring
The classical spectral curve for the worldsheet theory of the AdS5×S5 lambda superstring is constructed. The lambda string is interpreted as a regularized, non-abelian T-dual of the AdS5×S5 superstring with respect to the full PSU(2, 2|4) symmetry. The form of the curve is identified as the semi-classical limit of a …
