Description

Based on our previous series of work, we present the full resummation at RG-improved leading order for $h\rightarrow\gamma\gamma$ decay amplitudes induced by light quarks. We analytically show that endpoint divergences cancel in the plus-type subtraction scheme after scale evolution and use a slicing method to do the numerical evaluation. We find logarithms beyond NLL are significant.
