...in the 7-gluon amplitude discussed in appendix B, they come from much simpler superspace expressions which can be analysed by hand. 6 See however the tree-level, one-loop and two-loop calculations of =-=[22]-=- to check how the choice has to be taken into account at higher-loops. 7 One also has to evaluate the functional integration of the exponentials ∏ : eik i ·X(zi) :, but they will not appear explicitly...
