WebOct 4, 2024 · 2 Answers Sorted by: 3 You can perform the Feynman trick like Konstantinos suggested. Alternatively, you can perform the Schwinger proper-time trick, which I personally find simpler and easier in practice. The Schwinger trick is basically substituting 1 a = ∫ 0 ∞ d τ e − a τ. The denominator a usually comes from a propagator of a virtual … WebI'm assuming you are talking about a special case of Leibniz's rule, which is now often referred to as "Feynman's method". The gist of the method consists of putting a parameter in the integral you are trying to evaluate, differentiating with respect to that parameter, and then solving the resulting differential equation. 1.
