| contents | The decays governed by the flavor-changing-neutral-current transitions (FCNC), such as $b\to s\ell^{+}\ell^{-}$, provide an important tool to test the physics in and beyond the Standard Model (SM). This work focuses on investigating the FCNC process $B_{c}\to D_{s}^{*} \left(\to D_{s}π\right)\ell^{+}\ell^{-}(\ell=e,μ,τ)$. Being an exclusive process, the initial and final state meson matrix elements involve the form factors, which are non-perturbative quantities and need to be calculated using specific models. By using the form factors calculated in the covariant light-front quark model, we analyze the branching fractions and angular observables such as the forward-backward asymmetry $A_{FB}$, polarization fractions (Longitudinal and transverse) $F_{L(T)}$, CP asymmetry coefficients $A_{i}$ and CP-averaged angular coefficients $S_{i}$, both in the SM and some new physics (NP) scenarios. Some of these physical observables are a potential source of finding the physics beyond the SM and help us distinguish various NP scenarios. |
