A measurement of the B0 --> J/psi pi+pi- branching fraction

Creators

Description

We present a measurement of the branching fraction for the decay of the neutral B meson into the final state J/ψπ+π-. The data set contains approximately 56 million B(bar B) pairs produced at the Υ(4S) resonance and recorded with the BABAR detector at the PEP-II asymmetric-energy e+e- storage ring. The result of this analysis is Β(B 0 → J/ψ π+π-) = (4.6 ± 0.7 ± 0.6) x 10-5, where the first error is statistical and the second is systematic. In addition we measure Β(B0 → J?ψρ0) = (1.6 ± 0.6 ± 0.4 ) x 10-5
