Hello fellow physicists,
during some calculations for a project regarding Renormalization, I had a difficulty in computing a derivative of a loop integral in Yukawa theory. The thing i'm reffering to can be found in Peskin and Schroeder's book, Introduction to QFT , in Chapter 10 page 329330. Question #1: How the gamma function's argument changes from "1d/2" (10.33) to "2d/2" (10.35) ? Question #2: Could please somebody show me a detailed calculation of the derivation? I cannot get the finel form, with "x(1x)" in the numerator and plus the denominator has power "2d/2" and i think that normally the power should be "d/2" Thank you very much in advance..
