Measurements of the bottom quark mass

TL;DR

This paper reviews recent measurements of the bottom quark mass from ALEPH and DELPHI, demonstrating consistency with QCD predictions across different energy scales using various observables and jet algorithms.

Contribution

It provides a comprehensive analysis of bottom quark mass measurements at the Z peak and Upsilon scale, confirming the running of the mass as predicted by perturbative QCD.

Findings

Measurements are consistent across different energy scales.

Jet algorithms and observables are effectively used for mass determination.

Results support the predicted running of the bottom quark mass.

Abstract

I will review new measurements of the b quark mass, presented at this conference by ALEPH and DELPHI. A large set of observables has been used and detailed studies on jet algorithms have been performed. These measurements at the Z peak are consistent with the results obtained at the Upsilon scale when assuming the running of the b quark mass as predicted by perturbative QCD.
