Abstract
We show that, owing to discrete photon emissions, an electron colliding with a high intensity laser field can acquire a significant transverse momentum. This is in contrast to the case of a (continuously radiating) classical particle which, in a plane wave field, is shown to be unable to gain transverse momentum. Via numerical simulations, we show that this scattering behaviour is manifest in collisions with a realistic laser pulse of intensity within reach of current technology, and we propose it as a measurable signature of strong-field quantum electrodynamics.
