- Abstract
We present a new measurement of the bottom quark mass in the MSbar scheme at the renormalization scale of the Higgs boson mass from measurements of Higgs boson decay rates at the LHC: mb(mH ) = 2.60+0.36−0.31 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.
