N2 - The decay Bso→J/ψπ +π - can be exploited to study CP violation. A detailed understanding of its structure is imperative in order to optimize its usefulness. An analysis of this three-body final state is performed using a 1.0fb -1 sample of data produced in 7TeV pp collisions at the LHC and collected by the LHCb experiment. A modified Dalitz plot analysis of the final state is performed using both the invariant mass spectra and the decay angular distributions. The π +π - system is shown to be dominantly in an S-wave state, and the CP-odd fraction in this B̄s0 decay is shown to be greater than 0.977 at 95%confidence level. In addition, we report the first measurement of the J/ψπ +π - branching fraction relative to J/ψ of (19.79±0.47±0.52)%. © 2012 CERN. Published by the American Physical Society under the terms of the.
