We first prove a general result as follows.

By Proposition 7.1, our goal is reduced to evaluating the sum

Write

so that

Lemma 8.2. Suppose T < x < P. Then for µ = 6, 7

where

Proof. The sum is equal to

We move the contour of integration to the vertical segments

and to the two connecting horizontal segments

It follows by Lemma 5.6 that

The result now follows by direct calculation.

Combining these results with Lemma 8.3, we find that the integral (8.9) is equal to

The result now follows by direct calculation.
