Radiative corrections modify tracer particle dispersion

We study a tracer particle coupled to a scalar Bose field in the limit of infinite field propagation speed. For initial states without field excitations, we derive an effective dynamics where the particle propagates with a modified dispersion relation. This can be understood as radiative corrections due to interactions with virtual bosons.
