Workshop on S-matrix Bootstrap

September 9-13, 2019

ICTP-SAIFR, São Paulo, Brazil

Auditorium of IFT-UNESP


The goal of this very informal workshop is to bring together specialists on different topics like the conformal bootstrap, 2D integrable S-matrices, lattice field theory, effective field theories and flux tubes, dispersion relations approaches and string theory amplitudes.

The workshop is supported by the Simons Bootstrap collaboration and is already in its third edition. The first was in EPFL and the second in the Azores. As in the previous editions, we plan to have a very informal gathering, with 3 talks in the morning and free afternoons for discussions.

There is no registration fee.
