Higgs Decay To bb: Different Approaches To Resummation Of QCD Effects
Abstract
The comparison between parameterisations of the perturbation results for the decay width of the Standard Model Higgs boson to bb-quarks pairs, based on application of MS-scheme running quark mass and pole b-quark mass, are presented. In the case of the latter parameterisation taking into account of order O(αs3) term is rather important. It is minimising deviations of the results obtained at the O(αs2) level from the results, which follow from the running quark mass approach
