No Sommerfeld resummation factor in e+e- → p(p)over-bar?

The Sommerfeld rescattering formula is compared to the e(+)e(-) -> p (p) over bar BABAR data at threshold and above. While there is the expected Coulomb enhancement at threshold, two unexpected outcomes have been found: the modulus of the proton form factor is normalized to one at threshold, i.e. vertical bar G(p)(4M(p)(2))vertical bar = 1, as a pointlike fermion, and, moreover, data show that the resummation factor in the Sommerfeld formula is not needed. Other e(+)e(-) -> baryon-antibaryon cross-sections show similar behavior near threshold.
