We present a unified treatment of the conserved asymptotic charges associatedwith any bosonic massless particle in any spacetime dimension. In particular weprovide master formulae for the asymptotic charges and the central extensionsin the corresponding charge algebras. These formulae can be explicitlyevaluated for any given theory. For illustration we apply them toelectromagnetism and gravity, thereby recovering earlier results.
