  7. This sum rule is the electroproduction counterpart to the Adler sum rule and indeed\(\int\limits_0^\infty {dvW_2 (q^2 ,v) = 1} \) to second order ing. However, Fig. 1b) gives a contribution toW 2 which is a function ofs=q 2+2ν+m 2 and therefore\(\int {dvW_2 \ne } \int {\left( {d\omega /\omega } \right)F_2 \left( \omega \right)} \). SeeJ. M.
