Abstract
Recent experimental data on the space-like and time-like form factors of the proton are analyzed by means of a dispersive procedure. Both the space-like data, from Jlab and the time-like ones from FENICE at ADONE, DM2 at DCI and E835 at Fermilab are unexpected, for instance all these results are inconsistent with the low energy scaling. In light of these good and bad news, we try to gain some information about the properties of the ratio Gp E(q2)/Gp M(q2), by using a dispersive approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
