摘要：

We study the dual relationship between the resonances and the scaling curve for the inelastic structure function nuW2 in the Q2 range 1 to 17 (GeV/c)2. We focus on an exception to the rule that resonance bumps fall with increasing Q2 at the same rate as the background, namely, the DELTA(1232), for which the resonance falls faster than the background. We show that nuW2, averaged over suitable ranges of x, yields the smooth scaling curve seen at higher values of Q2 at the same values of x, for all resonance regions. The fall of the DELTA(1232) and corresponding rise of the background hints at a common dynamics for both.
