abstract
We report the first observation of $B^0 \to X(3872) (K^{+}\pi^{-})$ and evidence for $B^+ \to X(3872) (K^{0}\pi^{+})$. We measure the product of branching fractions for the former to be ${\cal B}(B^0 \to X(3872) (K^+ \pi^-)) \times {\cal B}(X(3872) \to J/\psi \pi^+ \pi^-) = (7.9 \pm 1.3(\mbox{stat.})\pm 0.4(\mbox{syst.})) \times 10^{-6}$ and find that $B^{0}\to X(3872) K^{*}(892)^{0}$ does not dominate the $B^{0}\to X(3872)K^{+}\pi^{-}$ decay mode. We also measure ${\cal B}(B^+ \to X(3872) (K^0 \pi^+)) \times {\cal B}(X(3872) \to J/\psi \pi^+ \pi^-) = (10.6 \pm 3.0(\mbox{stat.}) \pm 0.9(\mbox{syst.})) \times 10^{-6}$. This study is based on the full data sample of 711~fb$^{-1}$ ($772\times 10^6 B\bar B$ pairs) collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB collider.

Radiative decay of $\chi_{c1}$ states in effective Lagrangian approach
A triangle-loop effective Lagrangian model predicts chi_c1(3872) radiative branching fractions tens of times above LHCb measurements, supporting a non-charmonium interpretation.
