Phenomenology of IR-renormalons in inclusive processes

We have compared the existing experimental data on the leading power corrections to the structure functions F-2(x, Q(2)), F-3(x, Q(2)), and F-L(x,Q(2)) with the IR-renormalon model predictions for higher-twist contributions. Our analysis shows that the model properly describes the x-dependence, but typically falls short by a factor 2 or 3...More
