Using 383×106 B pairs from the BABAR data sample, we report results for branching fractions of six charged B-meson decay modes, where a charged kaon recoils against a charmless resonance decaying to K* or final states with mass in the range (1.2–1.8) GeV/c2. We observe a significant enhancement at the low K* invariant mass which is interpreted as B+(1475)K+, find evidence for the decay B+(1295)K+, and place upper limits on the decays B+(1405)K+, B+f1(1285)K+, B+f1(1420)K+, and B+(1680)K+.

Abstract
Using 383×106 B pairs from the BABAR data sample, we report results for branching fractions of six charged B-meson decay modes, where a charged kaon recoils against a charmless resonance decaying to K* or final states with mass in the range (1.2–1.8) GeV/c2. We observe a significant enhancement at the low K* invariant mass which is interpreted as B+(1475)K+, find evidence for the decay B+(1295)K+, and place upper limits on the decays B+(1405)K+, B+f1(1285)K+, B+f1(1420)K+, and B+(1680)K+.File in questo prodotto:
