英文摘要	Transverse momentum dependence in the perturbative calculation of the pion electromagnetic form factor is re-analyzed. It is found that (a) the intrinsic transverse momentum dependence associated with the pion wave function significantly suppresses perturbative prediction for the pion form factor at the energy region of a few GeV, and (b) the transverse momentum dependence in the fermion propagator of the hard scattering leads to a mild reduction of the perturbative calculation. Our formalism is available for both the intermediate energy region (Q similar to a few GeV) and the asymptotic energy region (Q --> asymptotic to).
