Experimental review of the nucleon electroweak form factors Original Research Article

Since more than 50 years, lots of results have been obtained on the nucleon electromagnetic form factors and their Q2-dependence (up to 31 (GeV/c)2 for GM) through elastic electron scattering off the nucleon. This is far from being the case for the electroweak form factors which are very poorly known and especially for the induced pseudoscalar one which is the least known of all the nucleon form factors. In this review we present the available results on these electroweak form factors and some of the planned experiments to improve our knowledge of these fundamental quantities.
