| Summary: | Title screen The time-integrated untagged Dalitz plot of the three-body hadronic charmless decay B¯ 0 → K0 Sπþπ− is studied using a pp collision data sample recorded with the LHCb detector, corresponding to an integrated luminosity of 3.0 fb−1. The decay amplitude is described with an isobar model. Relative contributions of the isobar amplitudes to the B¯ 0 → K0 Sπþπ− decay branching fraction and CP asymmetries of the flavor-specific amplitudes are measured. The CP asymmetry between the conjugate B¯ 0 → K ð892Þ−πþ and B0 → K ð892Þþπ− decay rates is determined to be −0.308 0.062. |
