Quark-Hadron Duality and Intrinsic Transverse Momentum
Abstract
It is demonstrated in several exclusive processes involving the pion that a local quark-hadron duality prescription is equivalent to using an effective q q (two-body) light-cone wave function (LD)(x,k) for the pion. This wave function models soft dynamics of all higher qG … G q Fock components of the standard light-cone approach. Contributions corresponding to higher Fock components in a hard regime appear in this approach as radiative corrections and are suppressed by powers of αs/π.
