Description
In this talk I will briefly present our recent RBC/UKQCD result for isospin-breaking corrections to leptonic decay rates. With the leading systematic uncertainty coming from unknown finite-volume effects, I will discuss the analytical evaluation of these at order $1/L^3$. This order is particularly complicated in certain formulations of finite-volume QED, and requires better understanding for future precision calculations in lattice QCD+QED.
