Different spin-parity hypotheses are tested via a helicity amplitude analysis of the processes e+e??Ds?+Ds?, D?0D0 and D?+D?, with Ds?+?Ds+?, D?0?D0?0, and D?+?D+?0. The results confirm the quark model predictions. © 2023 The Author(s)eninfo:eu-repo/semantics/openAccessBesıııCharmed MesonSpin And ParityArticle8462-s2.0-8517609591310.1016/j.physletb.2023.138245Q1
