THEO
1  AUBERT 2010A determine the ${\mathit {\mathit b}}$- and ${\mathit {\mathit c}}$-quark masses from a fit to the inclusive decay spectra in semileptonic ${{\mathit B}}$ decays in the kinetic scheme.
2  ABDALLAH 2006B determine ${\mathit m}_{{{\mathit b}}}−{\mathit m}_{{{\mathit c}}}$ from moments of the hadron invariant mass and lepton energy spectra in semileptonic inclusive ${{\mathit B}}$ decays.
3  Determine ${\mathit m}_{{{\mathit b}}}−{\mathit m}_{{{\mathit c}}}$ from a global fit to inclusive ${{\mathit B}}$ decay spectra.
