Asymptotic behavior of the Sudakov form factor in quantum chromodynamics

In this paper we give an algorithm to compute the asymptotic behavior of the on-shell quark form factor in the limit of large momentum transfer (Sudakov form factor) in Abelian and non-Abelian gauge theories. We ignore terms which are suppressed by a power of momentum transfer, but keep all nonleading logarithms of the momentum transfer and all powers of the coupling constant.
