Alessandro Torrielli’s paper on “The all-loop integrable spin-chain for strings on AdS_3 x S^3 x T^4: the massive sector” has been accepted for publication in the Journal of High-Energy Physics. The co-authors are Riccardo Borsato (Utrecht), Olof Ohlsson Sax (Utrecht), Alessandro Sfondrini (Utrecht), and Bogdan Stefansks (City U, London). In the paper they bootstrap the all-loop dynamic S-matrix for the homogeneous psu(1,1|2)^2 spin-chain believed to correspond to the discretization of the massive modes of string theory on AdS_3 x S^3 x T^4. The S-matrix is the tensor product of two copies of the su(1|1)^2 invariant S-matrix constructed recently for the d(2,1;alpha)^2 chain, and depends on two antisymmetric dressing phases. They write down the crossing equations that these phases have to satisfy. Furthermore, they present the corresponding Bethe Ansatz, which differs from the one previously conjectured, and discuss how the construction matches several recent perturbative calculations.
