Group constraint relations for five-point amplitudes in gauge theories with SO(N) and Sp(2N) groups
Linear constraint relations among loop-order five-point color-ordered amplitudes in SO(N) and Sp(2N) gauge theories are derived with the group-theoretic method. These constrains are derived up to four-loop order. It is found that in both theories, there are n=6,22,34,44,50 linear constraint relation...
