This study focuses on estimating the strong coupling constants of charmed and bottom mesons, such as B⁎, D⁎, B1, and D1, in relation to light pseudoscalar and axial vector states including π−, K−, a1−, b1−, K1(1270), and K1(1400). We wil

Abstract In this work, a Hard-Wall AdS/QCD model with 4 flavours is utilized to calculate the transition form factors for the semileptonic $$D\rightarrow (V, A, S)\,\ell \,\nu _{\ell }$$ D → ( V , A , S ) ℓ ν ℓ . These decays occur by $$c \rig

Abstract In phenomenology of quantum chromodynamics (QCD), charmed meson vertices are useful tools to study the final-state re-scattering effects in the hadronic B decays. The strong couplings of charm mesons vertices, are related to the basic parame
