The paper “AdS3 integrability, Sine-Gordon and fractional supersymmetry“, with author Alessandro Torrielli, has been accepted for publication in Physical Review Research as a regular article. A final form preprint in available on the arXiv (link here). The massless S-matrix of the pure RR AdS3 X S3 X T4 theory is very similar but not quite the same as Fendley-Intriligator’s N=2 S-matrix, in turns related to Sine-Gordon taken at a special coupling. In this short note Alessandro reviews the reason why supersymmetry emerges but with a fractional statistics of the particles. This result is then used to obtain a very simple interpolating S-matrix between massless AdS3 and Sine-Gordon. Full details are available at the above link.
