Observation of $B^{+}\to \ddot{I}{‡}_{c0}{K}^{+}$

Abstract

We report the first observation of the decay $B^{+}\to \ddot{I}{‡}_{c0}{K}^{+}$ using 21.3 fb${}^{-1}$ of data collected by the Belle detector at the $\hat{I}\yen$(4S) resonance. The preliminary result for the branching fraction is $\mathcal{B}(B^{+}\to \ddot{I}{‡}_{c0}{K}^{+})=(8.0_{-2.4}^{+2.7}\pm 1.0\pm 1.1)\times 10^{-4}$ where the first error is statistical, the second is systematic, and the third comes from the uncertainty in the $\ddot{I}{‡}_{c0}\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}$ branching fraction.
