mb at mH: The Running Bottom Quark Mass and the Higgs Boson

We present a new measurement of the bottom quark mass in the MS scheme at the renormalization scale of the Higgs boson mass from measurements of Higgs boson decay rates at the LHC: -0.31 GeV. The measurement has a negligible theory uncertainty and excellent prospects to improve at the HL-LHC and a future Higgs factory. Confronting this result and mb(mb) from low-energy measurements and mb(mZ) from Z-pole data, with the prediction of the scale evolution of the renormalization group equations, we find strong evidence for the running of the bottom quark mass.

Automated summary

In this study, a new measurement of the bottom quark mass in the MS scheme at the renormalization scale of the Higgs boson mass is presented. The measurement shows evidence for the running of the bottom quark mass, which has important implications for future experiments.
