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.

The idea for this analysis goes back to the LEP days and was revived in a DESY-IFIC workshop organized by K. Lipka. We thank Junping Tian for his inputs on the ILC potential and Stefano Catani for valuable comments.
