    Meson Decay Constants from Isospin Mass Splittings in the Quark Model

    Full text link
    Decay constants of DD and BB mesons are estimated within the framework of a heavy-quark approach using measured isospin mass splittings in the DD, DD^*, and BB states to isolate the electromagnetic hyperfine interaction between quarks. The values fD=(262±29)f_D = (262 \pm 29) MeV and fB=(160±17)f_B = (160 \pm 17) MeV are obtained. Only experimental errors are given; possible theoretical ambiguities, and suggestions for reducing them, are noted.Comment: 7 pages, LaTeX, EFI-92-3
