Search for the Theta(1540)+ pentaquark using kaon secondary interactions at Belle
The Belle Collaboration, K. Abe
Using kaon secondary interactions in the material of the Belle detector, we search for both inclusive and exclusive production of the Theta(1540)+. We set an upper limit of 2.5% at…
Measurement of Branching Fractions for at Belle
The Belle Collaboration, N. Soni
We have measured the branching fractions for the exclusive decay modes using a data sample collected by the Belle detector at the KEKB a…
Observation of B+->Lambda_c+Lambda_c-K+ and B0->Lambda_c+Lambda_c^-K0 decays
The Belle Collaboration, N. Gabyshev
We report first measurements of the doubly charmed baryonic B decays B->Lambda_c+Lambda_c-K. The B+->Lambda_c+Lambda_c-K+ decay is observed with a branching fraction of (6.5+1.0-0.…
Search for the b --> d gamma process
The Belle Collaboration, D. Mohapatra
We report the results of a search for the flavor-changing neutral current process b --> d gamma using a sample of 275 million B meson pairs accumulated by the Belle detector at KEK…
Determination of |V_ub| from Measurements of the Inclusive Charmless Semileptonic Partial Rates of B Mesons using Full Reconstruction Tags
Belle Collaboration, I. Bizjak
We present a measurement of the Cabibbo-Kobayashi-Maskawa matrix element |V_ub|, based on 253 fb^-1 of data collected by the Belle detector at the KEKB e^+e^- asymmetric collider.…
Measurement of |V_ub| near the endpoint of the electron momentum spectrum from semileptonic B-meson decays
The Belle Collaboration, A. Limosani
We report measurements of partial branching fractions of inclusive charmless semileptonic -meson decays at the endpoint of the electron momentum spectrum. The measurements are m…
