Wilson Coefficients and Natural Zeros from the On-Shell Viewpoint
We show how to simplify the calculation of the finite contributions from heavy particles to EFT Wilson coefficients by using on-shell methods. We apply the technique to the one-loop calculation of g − 2 and Hγγ, showing how finite contributions can be obtained from the product of tree-level amplitud...
