Scale-invariant total decay width Γ(H → b b ¯ $$ b\overline{b} $$ ) using the novel method of characteristic operator

Abstract According to the renormalization group invariance, any physical observable should be invariant under different renormalization schemes and scales. Nevertheless, a fixed-order pQCD approximant cannot inherently satisfy this requirement, giving rise to the conventional scheme-and-scale ambigu...
