Observation of B+ -> chic0 K+
Abstract
Using a sample of 31.3 x 106 BB$ pairs collected with the Belle detector at the Y(4S) resonance, we make the first observation of the charged B meson decay to chic0 and a charged kaon. The measured branching fraction is Br(B+ -> chic0 K+)=(6.0+2.1-1.81.1)x10-4, where the first error is statistical, and the second is systematic.
