abstract

We present a new measurement of the bottom quark mass in the $\bar{MS}$ scheme at the renormalization scale of the Higgs boson mass from measurements of Higgs boson decay rates at the LHC: $m_b(m_H)= 2.60^{+0.36}_{-0.31}$ 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 $m_b(m_b)$ from low-energy measurements and $m_b(m_Z)$ 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.

    hep-ex 2026-08 accept novelty 6.0 of 10

    The combined ATLAS Higgs measurements agree with the Standard Model and yield a self-coupling modifier kappa_lambda = 1.3 (+3.1/-1.6), a total width of 3.6 (+2.1/-1.6) MeV, and a b-quark running mass of 2.73 (+0.27/-0...

    hep-ph 2025-11 conditional novelty 6.0 of 10

    With a spin/color-weighted entanglement entropy built from Higgs branching ratios, the Standard Model Higgs and W masses sit near the global maximum, and the preferred coupling ratio is SM-like.
