Abstract
- We compute the conserved charges associated with the asymptotic symmetries of massless particles by examining their free theory in Minkowski spacetime. We give a procedure to systematically deduce the fall off of the massless fields at spatial infinity and show that it has a universal behaviour when expressed in tangent space. We do this for generic massless particles. We do not impose gauge fixing conditions which allows us to uncover new nonzero charges for the graviton beyond the well-known supertranslation charges. We also compute conserved charges in the dual formulations of certain low spin particles and argue that this leads to an infinite number of new conserved charges.<br />Comment: 25 pages.
