- W2963399318 abstract "From the fact that the nonperturbative self-energy contribution $C_{rm SE}$ to the heavy meson mass is small: $C_{rm SE}(bbar{b})=0$; $C_{rm SE}(cbar{c})cong -40$ MeV cite{ref.01}, strong restrictions on the pole masses $m_b$ and $m_c$ are obtained. The analysis of the $bbar{b}$ and the $cbar{c}$ spectra with the use of relativistic (string) Hamiltonian gives $m_b$(2-loop)$=4.78pm 0.05$ GeV and $m_c$(2-loop)$=1.39 pm 0.06$ GeV which correspond to the $bar{rm MS}$ running mass $bar{m}_b(bar{m}_b)=4.19pm 0.04$ GeV and $bar{m}_c(bar{m}_c)=1.10pm 0.05$ GeV. The masses $omega_c$ and $omega_b$, which define the heavy quarkonia spin structure, are shown to be by $sim 200$ MeV larger than the pole ones." @default.
