The results are B ( B 0 → K * 0 K + K − ) = ( 27.5 ± 1.3 ± 2.2 ) × 10 − 6 , B ( B 0 → K * 0 π + K − ) = ( 4.6 ± 1.1 ± 0.8 ) × 10 − 6 , and B ( B 0 → K * 0 π + π − ) = ( 54.5 ± 2.9 ± 4.3 ) × 10 − 6 . The first errors quoted are statistical and the second are systematic. An upper limit is set for B ( B 0 → K * 0 K + π − ) < 2.2 × 10 − 6 at 90% confidence level. We also present measurements of C P -violating asymmetries for the observed decays.8 p.application/pdfeng(c) American Physical Society, 2007Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article5581752019-04-04info:eu-repo/semantics/openAccess
