These measurements are sensitive to potential new-physics particles which could enter the b → s ( d ) loop transitions. The analysis is performed on a data sample consisting of 383 × 10 6 B ¯¯¯ B pairs collected with the BABAR detector at the PEP-II e + e − asymmetric energy collider. We observe the inclusive B → π + X process, and we set upper limits for B → K + X and B → K 0 X . Our results for these inclusive branching fractions are consistent with those of known exclusive modes, and exclude large enhancements due to sources of new physics.
