19 Dec 2002 | | Journal: | Phys.Lett. B554 (2003) 133-140 DOI: 10.1016/S0370-2693(03)00003-0 | | Subject: | hep-ph hep-ex | | Affiliation: | MPI Munich | | Abstract: | A detailed compilation of uncertainties in the MSbar bottom quark mass m_b(m_b) obtained from low-n spectral sum rules at order alpha_s^2 is given including charm mass effects and secondary b production. The experimental continuum region above 11.1 GeV is treated conservatively. An inconsistency of the PDG averages for the electronic partial widths of Upsilon(4S) and Upsilon(5S) is pointed out. From our analysis we obtain m_b(m_b)=4.20pm 0.09 GeV. The impact of future CLEO data is discussed. | | Source: | arXiv, hep-ph/0212297 | | Services: | Forum | Review | PDF | Favorites | |
