Measurement of the relative branching fractions of $B^{+}\to h^{+}{h}^{\prime +}{h}^{\prime -}$ decays

Abstract

The relative branching fractions of $B^{+}\to h^{+}{h}^{\prime +}{h}^{\prime -}$ decays, where $h^{(\prime )}$ is a pion or kaon, are measured. The analysis is performed with a data sample, collected with the LHCb detector, corresponding to an integrated luminosity of $3.0{\mathrm{fb}}^{-1}$ of $pp$ collisions. The results obtained improve significantly on previous measurements of these quantities, and are important for the interpretation of Dalitz plot analyses of three-body charmless hadronic decays of $B^{+}$ mesons.
