    • Abstract

       

      We derive sum rules for the structure functionV(x) for the ‘three-photon’ processe±+pe±+γ+X which can distinguish between various colour models below colour threshold, independently of the quark and gluon distributions. A careful study of the sum rule forV(x) in the broken colour gauge theory model can in principle be used to determine the colour gluon mass. Invoking the specific assumptions of the dominance ofp-type quarks and neglecting the sea of quark-antiquark pairs, we also obtain bounds forV(x) in terms ofvW2 (x) which can distinguish between various colour models below colour threshold.
