| dc.description | We present a measurement of the branching fraction for the Cabibbo- and color-suppressed $B^0 \to χ_{c1}π^0$ decay based on a data sample of $657\times 10^6$ $B\bar B$ events collected at the $Υ(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We observe a signal of $40\pm9$ events with a significance of $4.7σ$ including systematic uncertainties. The measured branching fraction is $\mathcal {B}(B^0 \to χ_{c1} π^0) = (1.12\pm 0.25(\rm {stat.})\pm 0.12({\rm syst.}))\times 10^{-5}$. | |
