We present the observation of the decay as well as evidence of , with an 8.9 and a 3.6 standard deviation significance, respectively, using a data sample of 454×106 $$Υ(4S)→B \bar{B}$$ decays collected with the BABAR detector at the PEP-II B meson factory located at the Stanford Linear Accelerator Center (SLAC). The measured branching fractions are B( )=(1.7±0. 3±0.2)×10-4 and B(B+→χc0K*+)=(1.4±0. 5±0.2)×10-4, where the first quoted errors are statistical and the second are systematic. Finally, we obtain a branching fraction upper limit of B(B+→χc0K*+)<2.1×10-4 at the 90% confidence level.
