Observation of B+ -> a(1)(+)(1260)K-0 and B-0 -> a(1)(-)(1260)K+

Observation of B+ -> a(1)(+)(1260)K-0 and B-0 -> a(1)(-)(1260)K+

We present branching fraction measurements of the decays B+→a1+(1260)K0 and B0→a1-(1260)K+ with a1±(1260)→π π±π±. The data sample corresponds to 383×106 BB̄ pairs produced in e+e- annihilation through the Υ(4S) resonance. We measure the products of the branching fractions B(B+→a1+(1260)K0)B(a1+(1260...
