Two surprising effects related to electron-electron scattering in graphene are demonstrated: One is a long-lived anisotropic carrier distribution after THz excitation, and the other one is an unexpected sign reversal of the pump-probe signal in a magnetic field. The latter reflects an Auger scattering so strong that it overcomes the effect of optical pumping.
