Özet
© 2019 authors. Published by the American Physical Society.The decay D+→KS0π+π+π- is studied with an amplitude analysis using a data set of 2.93 fb-1 of e+e- collisions at the ψ(3770) peak accumulated by the BESIII detector. Intermediate states and nonresonant components, and their relative fractions and phases, have been determined. The significant amplitudes, which contribute to the model that best fits the data, are composed of five quasitwo-body decays KS0a1(1260)+, K̄1(1270)0π+ K̄1(1400)0π+, K̄1(1650)0π+, and K̄(1460)0π+, a three-body decay KS0π+ρ0, as well as a nonresonant component KS0π+π+π-. The dominant amplitude is KS0a1(1260)+, with a fit fraction of (40.3±2.1±2.9)%, where the first and second uncertainties are statistical and systematic, respectively.
