The paper “A study of integrable form factors in massless relativistic AdS_2“, co-authored by Daniele Bielli (Surrey & Milano-Bicocca – moving to Chulalongkorn University, Bangkok), Vaibhav Gautam, and Alessandro Torrielli, has been accepted for publication in the Journal of High Energy Physics (link to arXiv version here). In the paper, they initiate the study of form factors for the massless scattering of integrable AdS2 superstrings, where the difference-form of the S-matrix can be exploited to implement the relativistic form-factor bootstrap. The image below shows Figures 3-6 from the paper.
