This book was released on 2009 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report measurements of the branching fractions of neutral and charged B meson decays to final states containing a K1(1270) or K1(1400) meson and a charged pion. The data, collected with the BABAR detector at the SLAC National Accelerator Laboratory, correspond to 454 million B{bar B} pairs produced in ee− annihilation. We measure the branching fractions?(B° → K1(1270)+?− + K1(1400)+?−) = 3.1{sub 0.7}{sup +0.8} x 10−5 and?(B+ → K1(1270)°?+ + K1(1400)°?+) = 2.9{sub -1.7}{sup +2.9} x 10−5 (
