Abstract:
We discuss the Zamolodchikov-Faddeev algebra for the superstring sigmamodel
on AdS5 ? S5. We find the canonical su(2|2)2 invariant S-matrix satisfying the
standard Yang-Baxter and crossing symmetry equations. Its near-plane-wave expansion
matches exactly the leading order term recently obtained by the direct perturbative computation.
We also show that the S-matrix obtained by Beisert in the gauge theory framework
does not satisfy the standard Yang-Baxter equation, and, as a consequence, the corresponding
ZF algebra is twisted. The S-matrices in gauge and string theories however are
physically equivalent and related by a non-local transformation of the basis states which
is explicitly constructed.
