The ratio of the electromagnetic proton elastic form factors, GpE/GpM, has been measured at Jefferson Lab up to View the MathML source, by using the CEBAF 6 GeV electron beam, and revealing an unexpected and challenging physical behaviour. The 2014 scheduled 12 GeV upgrade will allow the measurement of GpE/GpM up to View the MathML source, by taking advantage of the new large-acceptance forward spectrometer Super BigBite (SBS) in Hall A. Measurements of neutron form factors in the region around 10 (GeV/c)2, where quark confinement plays an important role, are expected to show the behaviour already observed in the proton case.
