New Dressing Factors for AdS3/CFT2
Sergey Frolov, Alessandro Sfondrini
The worldsheet S matrix of strings on the background is almost entirely fixed by symmetries, up to five functions -- the dressing factors. These must sa…
Mirror Thermodynamic Bethe Ansatz for AdS3/CFT2
Sergey Frolov, Alessandro Sfondrini
We consider superstrings on the pure-Ramond-Ramond background. Using the recently-proposed dressing factors for the worldsheet S matrix, we formulate th…
Massless S matrices for AdS3/CFT2
Sergey Frolov, Alessandro Sfondrini
The AdS3/CFT2 correspondence features massless non-relativistic modes on the string worldsheet in lightcone gauge. We study in detail these excitations and highlight how they natur…
Graviton particle statistics and coherent states from classical scattering amplitudes
Ruth Britto, Riccardo Gonzo, Guy R. Jehu
In the two-body scattering problem in general relativity, we study the final graviton particle distribution using a perturbative approach. We compute the mean, the variance and the…
Four flavours, triality and bimodular forms
Johannes Aspman, Elias Furrer, Jan Manschot
We consider supersymmetric gauge theory with massive hypermultiplets. The duality group of this theory contains transformations acting on the…
CFT correlators, -algebras and Generalized Catalan Numbers
Robin Karlsson, Manuela Kulaxizi, Gim Seng Ng +2
In two spacetime dimensions the Virasoro heavy-heavy-light-light (HHLL) vacuum block in a certain limit is governed by the Catalan numbers. The equation for their generating functi…
