Particle-in-cell (PIC) simulation results of sustained acceleration ofelectron-positron (e+e-) plasmas by comoving electromagnetic (EM) pulses arepresented. When a thin slab of overdense e+e- plasma is irradiated withlinear-polarized ultra-intense short laser pulses from both sides, the pulsesare transmitted when the plasma is compressed to thinner than ~ 2 relativisticskin depths. A fraction of the plasma is then captured and efficientlyaccelerated by self-induced JxB forces. For 1 micron laser and 1021Wcm-2intensity, the maximum energy exceeds GeV in a picosecond.Comment: 10 pages, 4 figure
