We calculate the Oðα s Þ QCD corrections to the inclusive h → bb decay rate in the dimension-6 standard model effective field theory (SMEFT). The QCD corrections multiplying the dimension-6 Wilson coefficients which alter the hbb-vertex at tree-level are proportional to the standard model (SM) ones, so next-to-leading order results can be obtained through a simple rescaling of the tree-level decay rate. On the other hand, contributions from the operators Q bG and Q HG , which alter the gbb-vertex and introduce a hgg-vertex respectively, enter at Oðα s Þ and induce sizeable corrections which are unrelated to the SM ones and cannot be anticipated through a renormalization-group analysis. We present compact analytic results for these contributions, which we recommend to be included in future phenomenological studies.
