      abstract     = {Linear colliders rely on high-quality flat beams to achieve
                      the desired event rate while avoiding potentially
                      deleterious beamstrahlung effects. Here, we show that flat
                      beams in plasma accelerators can be subject to quality
                      degradation due to emittance mixing. This effect occurs when
                      the beam particles’ betatron oscillations in a nonlinearly
                      coupled wakefield become resonant in the horizontal and
                      vertical planes. Emittance mixing can lead to a substantial
                      decrease of the luminosity, the main quantity determining
                      the event rate. In some cases, the use of laser drivers or
                      flat particle beam drivers may decrease the fraction of
                      resonant particles and, hence, mitigate emittance
                      deterioration.},
