Abstract: The charged current weak production of Δ ( 1232 ) from the free proton target induced by the electron/positron in the intermediate energy range corresponding to the beam energy available at JLab and Mainz, has been studied. The results for the differential scattering cross section d σ d Q 2 , the angular distribution d σ d Ω Δ , and the total scattering cross section σ ( E e ) for both the electron and positron induced processes are presented, for the various energies in the range of 0.5–4 GeV. The cross section σ ( E e ) is found to be of the order of 10 − 39 cm 2 for the electron/positron energies in the few GeV range. The availability of electron/positron beams having well-defined energy and direction with very high luminosity of the order of 10 38 – 10 39 cm − 2 sec − 1 , makes it possible to observe the weak charged current production of Δ ( 1232 ) and determine the axial vector form factors C i A ( Q 2 ) ; ( i = 3 – 5 ) . The sensitivity of the differential cross section d σ d Q 2 to the subdominant form factors C 3 A ( Q 2 ) and C 4 A ( Q 2 ) is found to be strong enough, especially in the low Q 2 region, which can be used to determine them phenomenologically and to test the various theoretical models proposed to calculate them.
