The electromagnetic pion form factor and its phase
Pablo Sanchez-Puertas, Enrique Ruiz Arriola
In this work, we employ a dispersion relation that allows to recover the electromagnetic form factor of the pion from its modulus along the unitarity cut. Unlike the standard dispe…

The phase of the electromagnetic form factor of the pion
Enrique Ruiz Arriola, Pablo Sanchez-Puertas
We employ a dispersion relation that allows to recover the phase of the electromagnetic form factor of the pion from its absolute value above threshold. Compared to alternative app…
