| dc.description.abstract | Using a data sample of 772�106 BB pairs collected on the �'(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e-collider, we report the observation of B0?pp?+?- A nd the first observation of B+?pp?+?0. We measure a decay branching fraction of (0.83�0.17�0.17)�10-6 in B0?pp?+?-for M?+?-<1.22 GeV/c2 with a significance of 5.5 standard deviations. The contribution from B0?ppK0 is excluded. We measure a decay branching fraction of (4.58�1.17�0.67)�10-6 for B+?pp?+?0 with M?+?0<1.3 GeV/c2 with a significance of 5.4 standard deviations. We study the difference of the Mpp distributions in B0?pp?+?- A nd B+?pp?+?0. � 2020 authors. | en_US |
