The ρ-meson propagator is modified by insertions of the vacuum-polarization tensor due to charged pion pairs. The sum of all such contributing graphs via the Duffin–Kemmer formalism is seen to give a Breit–Wigner-type expression for the electromagnetic pion form factor. The width of the ρ meson is associated with the absorptive part of the pion form factor and at t = mρ2 we estimate fρππ2/4π = 2.5 using the experimental width Γρ = 125 ± 20 MeV.
