Description
A new method is presented to extract quark masses from collider data on Higgs production and decay rates. We find a value for the bottom quark MSbar mass at the scale of the Higgs boson mass of mb(mh) = 2.6 +/- 0.3 GeV from recent measurements by ATLAS and CMS. This result is compatible with the prediction of mb(mh) from the evolution of the world average for mb(mb) and thus provides further evidence for the scale evolution, or "running" of the bottom quark mass. Future precision measurements of Higgs decay rates are expected to improve this result considerably. We assess, in particular, the potential of a future "Higgs factory" electron-positron collider.
This abstract is related to the abstract presented by Adrian Irles and Seidai Tairafune, on determinations of the bottom quark mass in Z-boson production.
