Abstract

We perform an analysis of the D⁺→ K⁰ _Sπ⁺π⁰ Dalitz plot using a data set of 2.92 fb^-1 of e⁺e^- collisions at the ψ(3770) mass accumulated by the BESIII experiment, in which 166694 candidate events are selected with a background of 15.1%. The Dalitz plot is found to be well represented by a combination of six quasitwo- body decay channels [K⁰ _Sρ⁺, K⁰ _Sρ(1450)⁺, K^∗0π⁺, K⁰ (1430)⁰π⁺, K (1680)⁰π⁺, κ⁰π⁺] plus a small nonresonant component. Using the fit fractions from this analysis, partial branching ratios are updated with higher precision than previous measurements.

N2 - We perform an analysis of the D+→ K0 Sπ+π0 Dalitz plot using a data set of 2.92 fb-1 of e+e- collisions at the ψ(3770) mass accumulated by the BESIII experiment, in which 166694 candidate events are selected with a background of 15.1%. The Dalitz plot is found to be well represented by a combination of six quasitwo- body decay channels [K0 Sρ+, K0 Sρ(1450)+, K∗0π+, K0 (1430)0π+, K (1680)0π+, κ0π+] plus a small nonresonant component. Using the fit fractions from this analysis, partial branching ratios are updated with higher precision than previous measurements.
