    Investigation of P-wave scalar and S-wave pseudo-scalar charmonia semileptonic transitions to the Ds(D) meson in QCD
    (IOP Publishing, 2010) Dağ, Hüseyin; Azizi, K.; Bashiri, V.; Natural and Mathematical Sciences; DAĞ, Hüseyin
    In this work, the semileptonic decays of the scalar charmonium state Xc0 and the pseudo scalar charmonia states ηc(1s) and ηc(2s) into Ds and D mesons are analyzed. The form factors of the transitions Xc0 → Ds(D)_ν and ηc(1s, 2s) → Ds(D)_ν are calculated within the framework of the threepoint QCD sum rules. The results of the form factors are used to estimate the decay widths of the charmonia states into Ds(D)eν¯e and Ds(D)μν¯μ.
