Precise quark masses from sum rules
Matthias Steinhauser
TL;DR
This paper presents an improved method for accurately determining charm and bottom quark masses using sum rules applied to experimental and theoretical moments of the photon polarization function, resulting in precise $ar{ m MS}$ mass values.
Contribution
The paper introduces an enhanced analysis technique for extracting quark masses from sum rules, improving precision over previous methods.
Findings
Charm quark mass: 0.986(13) GeV at 3 GeV
Bottom quark mass: 3.609(25) GeV at 10 GeV
Provides more accurate quark mass values using sum rule analysis.
Abstract
In this contribution an improved analysis is described to extract precise charm and bottom quark masses from experimental and theoretical moments of the photon polarization function. The obtained mass values read GeV and GeV.
