Abstract

We show that the J/ψ→π+π- decay is a reliable source of information for the electromagnetic form factor of the pion at t=MJ/ψ2=9.6 GeV2 by using general arguments to estimate, or rather, put upper bounds on, the background processes that could spoil this extraction. We briefly comment on the significance of the resulting Fπ(MJ/ψ2).
