摘要：
We construct the most general composite operators of N = 4 SYM in Lorentz harmonic chiral (approximate to twistor) superspace. The operators are built from the SYM supercurvature which is nonpolynomial in the chiral gauge prepotentials. We reconstruct the full nonchiral dependence of the supercurvature. We compute all tree-level MHV form factors via the LSZ reduction procedure with on-shell states made of the same supercurvature.
