Query: Worldsheet two- and four-point functions at one loop in AdS(3) / CFT(2)   In this note we study worldsheet two- and four-point functions at the
one-loop level for the type IIA superstring in AdS(3) x S(3) x M(4) . We first
address the regularization ambiguity that appears in the dispersion relation
derived from integrability. We demonstrate that only the regulator treating all
fields equally respects worldsheet supersymmetry. This is done in an implicit
regularization scheme where all divergent terms are collected into master
tadpole-type integrals. We then investigate one-loop two-body scattering on the
string worldsheet and verify that a recent proposal for the dressing phase
reproduces explicit worldsheet computations. All calculations are done in a
near-BMN like expansion of the Green-Schwarz superstring equipped with quartic
fermions.
