Description:
Author(s): B. Ananthanarayan, Irinel Caprini, and Diganta Das We present a determination of the pion charge radius from high precision data on the pion vector form factor from both timelike and spacelike regions, using a novel formalism based on analyticity and unitarity. At low energies, instead of the poorly known modulus of the form factor, we use its phase... [Phys. Rev. Lett. 119, 132002] Published Thu Sep 28, 2017
