Popis: | The strange-quark mass is determined from finite energy and Laplace transform QCD sum rules for the two-point function involving strangeness changing vector currents and their divergences. Improved QCD input and experimental data in the I = 1 2 , S-wave Kπ amplitude are used to obtain: m s = 266 ± 29 MeV , or m s (1 GeV ) = 194 ± 4 MeV , where m s and m are the invariant and the running quark masses, respectively. |
