We consider winding conserving four point functions in the SL(2,R) WZW model for states in arbitrary spectral flow sectors. We compute the leading order contribution to the expansion of the amplitudes in powers of the cross ...

We consider a four-parameter family of point interactions in one dimension. This family is a generalization of the usual delta-function potential. We examine a system consisting of many particles of equal masses that are ...

We initiate the study of four-point functions of large BPS operators at any value of the coupling. We do it by casting it as a sum over exchange of superconformal primaries and computing the structure constants using ...

We calculate some extremal and non-extremal four-point functions on the sphere of certain chiral primary operators for strings on AdS 3×S3×T4. The computation is done for small values of the spacetime cross-ratio where ...

We obtain all planar four-point correlators of half-BPS operators in N= 4 SYM up to five loops. The ansatz for the integrand is fixed partially by imposing lightcone OPE relations between different correlators. We then fix ...
