Title: Observation of B0 Meson Decays to a1(1260)+- pi-+

Abstract

The authors present a measurement of the branching fraction of the decay B{sup 0} {yields} a{sub 1}{sup {+-}}(1260){pi}{sup {-+}} with a{sub 1}{sup {+-}}(1260) {yields} {pi}{sup {-+}}{pi}{sup {+-}}{pi}{sup {+-}}. The data sample corresponds to 218 x 10{sup 6} B{bar B} pairs produced in e{sup +}e{sup -} annihilation through the {Upsilon}(4S) resonance. The authors measure the branching fraction {Beta}(B{sup 0} {yields} a{sub 1}{sup {+-}}(1260){pi}{sup {-+}}){Beta}(a{sub 1}{sup {+-}}(1260){yields} {pi}{sup {-+}}{pi}{sup {+-}}{pi}{sup {+-}})=(16.6 {+-} 1.9 {+-} 1.5) x 10{sup -6}, where the first error quoted is statistical and the second is systematic.
