Query: Exact S-matrices for AdS_3/CFT_2   We propose exact $S$-matrices for the AdS_3/CFT_2 duality between Type IIB
strings on AdS_3 x S^3 x M_4 with M_4=S^3 x S^1 or T^4 and the corresponding
two-dimensional conformal field theories. We fix the complete two-particle
S-matrices for both those cases of AdS_3/CFT_2, on the basis of the symmetries
su(1|1) and su(1|1) x su(1|1), respectively preserved by their vacua. A crucial
justification comes from the derivation of the all-loop Bethe ansatz matching
exactly the recent conjecture proposed by [1] and [2].
