Charm meson couplings in hard-wall Holographic QCD

S. Momeni, M. Saghebfar

The four-flavor hard-wall holographic QCD is studied to evaluate the couplings of $(D^{_{- (*-)}}, D ˉ^{_{0}}, a_{1}^{_{-}})$ , $(D^{_{- (*-)}}, D ˉ^{_{0}}, b_{1}^{_{-}})$ , $(D_{s}^{_{-(*…

Helicity form factors for $D_{(s)} \to A ℓ ν$ process in the light-cone QCD sum rules approach

S. Momeni

The helicity form factors of the $D_{(s)} \to A ℓ^{+} ν$ with $A = a_{1}^{-}, a_{1}^{0}, b_{1}^{-}, b_{1}^{0}, K_{1} (1270)$ and $K_{1} (1400)$ are calculated in the light-cone sum rul…

$D D A$ , $D^{} D^{} A$ and $D^{*} D A$ vertices in the light-cone QCD and considering $B^{0} \to K_{1}^{+} π^{-}$ branching ratio

S. Momeni, R. Khosravi

We investigate the strong coupling constants of $D D A$ , $D^{*} D^{*} A$ and $D^{*} D A$ vertices in the framework of the light-cone QCD sum rules, where $A$ is an axial vector meson…

Semileptonic $D_{(s)} \to A ℓ^{+} ν$ and nonleptonic $D \to K_{1} (1270, 1400) π$ decays in LCSR

S. Momeni, R. Khosravi

In this work, the transition form factors are calculated for the semileptonic $D_{(s)} \to A ℓ^{+} ν$ where $A = a_{1}, b_{1}, K_{1} (1270, 1400)$ , i.e., $D^{+} \to a^{0}_{1} (b^{0}_{…

Semileptonic and nonleptonic decays of $D$ into tensor mesons with light-cone sum rule

S. Momeni, R. Khosravi, S. Ghaziasgar

Form factors of $D$ decays into $J^{P C} = 2^{++}$ tensor mesons are calculated in the light-cone sum rules approach up to twist-4 distribution amplitudes of the tensor meson. The mas…

Analysis of the semileptonic $B \to K_{1} ℓ^{+} ℓ^{-}$ transitions and non-leptonic $B \to K_{1} γ$ decay in the AdS/QCD correspondence

S. Momeni, R. Khosravi

We consider the axial-vector mesons $K_{1} (1270)$ and $K_{1} (1400)$ as a mixture of two $∣^{3} P_{1} ⟩$ and $∣^{1} P_{1} ⟩$ states with the mixing angle $θ$ that equal to $(-34\pm 13)^…
