摘要
The pion decay constant and the electromagnetic form factor are computed by using quark diagrams and projecting the bound-state wave function on the null plane. We show that the resulting formulas are the same as those of the Hamiltonian front-form scheme. The connection between the radius (r(pi)) and the pion decay constant (f(pi)) is studied using different models of confinement.
