DOWNLOAD EBOOKThe authors present measurements of partial branching fractions of B 2!KX, B 2!K° X, and B 2![pi]+X, where X denotes any accessible final state above the endpoint for B decays to charmed mesons, specifically for momenta of the candidate hadron greater than 2.34 (2.36) GeV for kaons (pions) in the B rest frame. These measurements are sensitive to potential new-phisics particles which could enter the b 2!s(d) loop transitions. The analysis is performed on a data sample consisting of 383 x 106 B{bar B} pairs collected with the BABAR detector at the PEP-II e+e− asymmetric energy collider. The results are in agreement with standard model predictions and exclude large enhancements of the inclusive branching fraction due to sources of new physics.
