摘要：We report preliminary results on 3-body B decays using a data sample of 21.3 fb−1 recorded at the (4S) resonance with the Belle detector at the KEK e+e− storage ring. With no assumption on the intermediate mechanisms, the following branching fractions have been measured for the rst time: B(B+ ! K+−+) = (58:57:1 8:8) 10−6; B(B+ ! K+K−K+) = (37:03:94:4) 10−6 and B(B0 ! K+−0) = (35:6+8:1 −7:7 5:2) 10−6: Results of studies for various intermediate two-body decays are also presented.
