| contents | All charmless $B \to PV\ell^+ν_\ell$ ($P$ denotes the light pseudoscalar meson and $V$ denotes the vector meson) decays have not been experimentally observed to date, but some of them might be measured in the near future. The charmless $B \to PV\ell^+ν_\ell$ decays with the axial-vector ($A$) resonance states, the tensor ($T$) resonance states and the excited vector ($V_{E,D}$) resonance states are studied based on flavor SU(3) analysis in this work, where $V_E$ contains $\{ρ(1450), K^*(1410), ω(1420), ϕ(1680)\}$ with quantum numbers $n^{2S+1}L_J=2^3S_1$ and $V_D$ contains $\{ρ(1700), K^*(1680), ω(1650), ϕ(2170)\}$ with quantum numbers $n^{2S+1}L_J=1^3D_1$. The hadronic amplitudes of the $B \to A/T \ell^+ν_{\ell}$ decays are related by the nonperturbative parameters, and the branching ratio predictions of $B \to A/T/V_{E,D} \ell^+ν_{\ell}$ are obtained, and then the branching ratios of the $B\to A(A\to PV)\ell^+ν_\ell$, $B\to T(T\to PV)\ell^+ν_\ell$, $B\to V_E(V_E\to PV)\ell^+ν_\ell$ and $B\to V_D(V_D\to PV)\ell^+ν_\ell$ are obtained by the narrow width approximation or further considering the width effects. We find that most branching ratios of the $B \to A \ell^+ν_{\ell}$ decays and many branching ratios of the $B\to A(A\to PV)\ell^+ν_\ell$ decays are on the order of $\mathcal{O}(10^{-4}-10^{-3})$, and all branching ratios with the tensor resonance states and the excited vector resonance states are small. Our results could be tested in the future BelleII and LHCb experiments. |
