D^＋→η^（＇）l＋ν_l semileptonic decays in light-cone sum rules
Abstract
We calculate the D → η transition form factor in light-cone sum rules by taking improved current correlators to avoid the pollution from the twist-3 wave function. We get consistent results of the D＋ → η^（＇）l＋νl decays with the experimental data. By compa
