Transverse momentum dependence in the perturbative calculation of pion form factor

Abstract

By reanalysing transverse momentum dependence in the perturbative calculation of pion form factor an improved expression of pion form factor which takes into account the transverse momentum dependenc in hard scattering amplitude and intrinsic transverse momentum dependence associated with pion wave functions is given to leading order, which is available for momentum transfers of the order of a few GeV as well as for $Q\to \infty$. Our scheme can be extended to evaluate the contributions to the pion form factor beyond leading order.
