The form factors are computed with the covariant light-front quark model, where uncertainties come from the decay constant of charmed meson.
The form factors are computed with QCD sum rules, where uncertainties are from the Borel parameters.
The form factors are computed with parameter (0.5) GeV using the WSB model.
The form factors are computed with flavor dependent parameter using the WSB model.
The form factors are computed with parameter using the WSB model.
