Double Higgs production is a unique collider process, enabling the determination of the Higgs self-coupling. However, it is exceedingly rare in the Standard Model, due to the cancellation between the standard triangle and box contributions to the amplitude. I will demonstrate an analytic understanding of this cancellation, and its implications for the impact of new physics on Higgs pair production. In particular, I will show how the invariant mass distribution in double Higgs production is sensitive to the spins of the particles in the loop diagrams.
