Abstract
The charmless three-body decays B(s)0â KS0h+hâ² â(where h(â²)= Ï, K) are analysed using a sample of pp collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3 fbâ1. The branching fractions are measured relative to that of the B0â KS0Ï+Ïâdecay, and are determined to be: (Formula Presented.) at 90% confidencelevel, where fs/fdrepresents the ratio of hadronisation fractions of the Bs0and B0mesons.File in questo prodotto:
