Dalitz plot studies of D0 → KS0π+π− decays in a factorization approach

A quasi two-body QCD factorization is used to study the D0 → KS0π+π− decays. The presently available high-statistics Dalitz plot data of this process measured by the Belle and BABAR Collaborations are analyzed together with the τ− → KS0π−ντ decay data. The total experimental branching fraction is a...
