Description
The semileptonic charmed meson decays are the ideal tools to explore the various aspects of heavy quark decays. We study the leptonic and semileptonic $D_s$ meson decays ($D_s \to \ell^+ \nu_{\ell}$ and $D_s \to \phi \ell^+ \nu_{\ell}$) in the framework of covariant quark model (CQM) with built-in infrared confinement. The CQM is an effective quantum field approach for the hadronic interaction based on effective Lagrangian of hadrons interacting with the constituent quarks. The required form factors are computed in the entire range of momentum transfer and used to determine semileptonic branching fractions. The computed branching fractions are in close resemblance with the recent BESIII data [arXiv:1709.03680] and other experimental results.
