Abstract

In this work, the semileptonic decays of the scalar charmonium state X c0 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)ℓν and ηc(1s, 2s) → Ds(D)ℓν are calculated within the framework of the three-point QCD sum rules. The results of the form factors are used to estimate the decay widths of the charmonia states into and . © 2010 IOP Publishing Ltd.
