How to get this result? The notation ##o(\Lambda^0)## means all terms constant in Lambda, which we ignore because we are interested in a large ##\Lambda## limit. Also, the implicit region of integration is all of ##\mathbb{R}^4##.

I managed to switch to spherical coordinates and integrate over the angular variables to pull put a factor of the surface area of the unit 3-sphere. The rest of the integral picks up a factor of ##q^3## and becomes an integration over dq from 0 to infinity.

From there, what is a quick way to get to the result? Is there some trick that lets you see the large Lambda behaviour while ignoring the constant terms?
