A dispersion-theoretic study of pion factor
Description
It is shown that the pion electromagnetic form factor satisfies a nonsubtracted dispersion relation if one of the pions is taken to be massless. It is possible pointed out that, by giantizing the theory on the light-cone, the mass extrapolation ambiguity due to one of the pions being massless can be overcome. This result is used to establish an upper bound on the pion charge radius
