Abstract
The Nachtmann moments of the singlet structure function F2νN(x, Q2) which contains the information of the mixing between quarks and gluons are predicted based on QCD in leading order approximations. The agreement with experimental data is fairly good. The energy momentum sum rule which is imposed on the Q2-dependent quark and gluon distribution function is not consistent with the Abelian vector gluon theory, but consistent with QCD. This fact concludes that the Abelian vector gluon theory with small fixed point is definitely excluded as the theory responsible for the strong interactions, whereas QCD is the most eligible one.
