One Loop Gluon Gluon Scattering in Light Cone Gauge
  We calculate the one loop amplitudes for the two gluon scattering process in light cone gauge with fermions and scalars circulating in the loop. This extends the earlier works, in which only the gluon circulates the loop. By putting all fields in the adjoint representation with N_f=2, N_s=6, the scattering amplitude of gluon by gluon in the special case of N=4 Super Yang-Mills can be obtained. The massive fermion and scalar with arbitrary representations are also considered.
