Precise Charm- and Bottom-Quark Masses: Recent Updates
Johann H. Kuhn
TL;DR
This paper reviews recent theoretical and experimental advances in precisely determining charm and bottom quark masses, highlighting the most accurate current measurements and analyzing associated uncertainties.
Contribution
It provides the latest precise values for charm and bottom quark masses, including a critical assessment of uncertainties and comparison with lattice results.
Findings
$m_c(3\text{GeV})=986(13)$ MeV and $m_b(m_b)=4163(16)$ MeV
Lattice determination of $m_c(3\text{GeV})=986(10)$ MeV
Most precise current measurements of these quark masses
Abstract
Recent theoretical and experimental improvements in the determination of charm and bottom quark masses are discussed. The final results, MeV and MeV represent, together with a closely related lattice determination MeV, the presently most precise determinations of these two fundamental Standard Model parameters. A critical analysis of the theoretical and experimental uncertainties is presented.
