"The decay widths have higher-order perturbative QCD corrections, and these are particularly important for the  decay which dominates over a wide range of (light) Higgs masses. The main effect…

When I started writing this blog, I wasn't sure about its direction, so I began by presenting something that I was curious about and hoped that others would find it interesting, while attempting to…
