Query: On electromagnetic and colour memory in even dimensions   We explore memory effects associated to both Abelian and non-Abelian
radiation getting to null infinity, in arbitrary even spacetime dimensions.
Together with classical memories, linear and non-linear, amounting to permanent
kicks in the velocity of the probes, we also discuss the higher-dimensional
counterparts of quantum memory effects, manifesting themselves in modifications
of the relative phases describing a configuration of several probes. In
addition, we analyse the structure of the asymptotic symmetries of Maxwell's
theory in any dimension, both even and odd, in the Lorenz gauge.
