Measurement of partial branching fractions of inclusive charmless B meson decays to K+, K0, and pi+
We present measurements of partial branching fractions of B-->K+X, B-->K0X, and B-->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 re...

description | We present measurements of partial branching fractions of B-->K+X, B-->K0X, and B-->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-physics particles which could enter the b-->s(d) loop transitions. The analysis is performed on a data sample consisting of 383×106BB[over-bar] 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-->K0X. 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. |
