Imprinting New Physics by using Angular profiles of the FCNC process B₂ Dₒ^* (\;Dₒ) ^+^-

The decays governed by the flavor-changing-neutral-current transitions (FCNC), such as b s^+^-, provide an important tool to test the physics in and beyond the Standard Model (SM). This work focuses on investigating the FCNC process B₂ Dₒ^* (Dₒ) ^+^- (=e, , ). 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 A₅₁, polarization fractions (Longitudinal and transverse) F₋ (ₓ), CP asymmetry coefficients A₈ and CP-averaged angular coefficients S₈, 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.
