Nuclear dependence of structure functions and ∧ QCD

We study quantitatively a model for the EMC effect. Here theA dependence of structure functions is computed using the evolution equations. The model has been tested by computing both the structure function and the EMC ratio. The Q2 and A dependence of the ratio, reported recently, are explained. However at low x an extra intrinsic component to the nuclear structure function is indicated. The model also implies anA dependent QCD scale parameter ∧, which seems to be borne out by the data
