Download or read book OBSERVATION OF EXCLUSIVE TWO-BODY B DECAYS TO KAONS AND PIONS. written by and published by . This book was released on 2003 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have studied two-body charmless hadronic decays of B mesons into the final states??, K?, and KK. Using 3.3 million B{bar B} pairs collected with the CLEO-II detector, we have made the first observation of the decays B° → K?−, B+ → K°?+, and the sum of B+ →?+?° and B+ → K+?° decays (an average over charge-conjugate states is always implied). We place upper limits on branching fractions for the remaining decay modes.
