Dalitz plot studies ofD⁰→K_S⁰π⁺π⁻decays in a factorization approach

Abstract

Abstract. A quasi two-body QCD factorization is used to study theThe presently available high-statistics Dalitz plot data of this process measured by the Belle and BABAR Collaborations are analyzed together with the τThe total experimental branching fraction is also included in the fits which show a very good overall agreement with the experimental Dalitz plot density distributions. The branching fractions of the dominant channels compare well with those of the isobar Belle or BABAR models. We show that the branching fractions corresponding to the annihilation amplitudes are significant.
