Demonstration of the Double Q2-Rescaling Model

In this paper we have demonstrated the double Q²-rescaling model (DQ²RM) of parton distribution functions of nucleon bounded in nucleus. For different χ regions in I-A deep inelastic scattering process we take different approaches: in high χ region (0.1 ≤ χ ≤ 0.7)we use the distorted QCD vacuum model which resulted from topologically multi-connected domain vacuum structure of nucleus; in low χ region (10^-4 ≤ χ ≤ 10^-3) we adopt the Glauber (Mueller) multi-scat tering formula for gluon coherently rescat tering in nucleus. From these two approaches we show that the rescaling parton distribution functions in bound nucleon are in good agreement with those we got from DQ²RM, thus the validity for this phenomenological model is demonstrated.
