Description
X(3872) and Y(4260) are famous for their exotic nature. We present
search for $B \to Y(4260) K$, $B \to X(3872) (\to \chi_{c1}\pi^0) K$ and
$B \to X(3915)(\to \chi_{c1} \pi^0) K$ at Belle based on the full data sample
accumulated by the Belle experiment at KEKB asymmetric energy $e^+ e^-$
collider. As no signal is found, upper limit on the product
branching fraction is provided.
We also report evidence of $B \to h_c K$ along with first observation of the
decay $\eta_c(2S)-> p \bar{p} \pi^+ \pi^-$ in Belle.
