Abstract
We report on a search for the decay and other charmless modes with a final state, including , nonresonant , , and . These results are obtained from a data sample containing pairs collected with the Belle detector at the KEKB asymmetric-energy collider. We set an upper limit on of at the 90% confidence level (C.L.). From our measurement and an isospin analysis, we determine the Cabibbo-Kobayashi-Maskawa phase to be degrees. We find excesses in and nonresonant with and significance, respectively. The corresponding branching fractions are less than and at the 90% C.L. In addition, we set 90% C.L. upper limits as follows: , , and .
