Revisiting the infrared physics of particles of arbitrary spin

After a brief overview of the recent developments relating different aspects of the infrared physics of spin-1 and spin-2 particles, I will revisit Weinberg's constraints on the S-matrix of massless higher-spin particles from the viewpoint of asymptotic symmetries in flat space. I will also discuss the hints that this analysis provides on possible higher-spin extensions of the BMS symmetry.
