We conducted a detailed study on the properties of the total decay width of the Higgs decay channel $ H\to gg $ up to $ H\to gg $ -order QCD corrections by using the newly suggested infinite-order scale-setting approach, which is based on both the principle of maximum conformality and intrinsic conformality. This approach is called PMC $ H\to gg $ . By using the PMC $ H\to gg $ approach, we observed that the conventional renormalization scale ambiguity in perturbative QCD calculation is eliminated, and the residual scale dependence due to unknown higher-order terms can also be highly suppressed. We then obtained an accurate perturbative QCD prediction on the total decay width, e.g., $ H\to gg $ keV, where the errors are squared averages of those from all the mentioned error sources.
