IFAE is partially funded by the CERCA program of the Generalitat de Catalunya. We perform a combined study of the two hadronic decays D+→K−π+π+ and D+s→K+K+π− using a detailed analysis of the semileptonic decays D+→K−π+ℓ+νℓ (ℓ=e, μ) thanks to the high-statistics dataset provided by the BESIII Collaboration. We propose simple and suitable amplitude parametrizations of the studied reactions that shall be of interest to experimentalists for upcoming analyses. These new parametrizations are based on the naïve-factorization hypothesis and the description of the resulting matrix elements in terms of well-known hadronic form factors, with special emphasis on the Kπ scalar and vector cases. Such form factors account for two-body final-state interactions which fulfill analyticity, unitarity, and chiral symmetry constraints. As a result of our study, we find that the P-wave contribution fits nicely within the naïve-factorization approach, whereas the S-wave contribution requires complex Wilson coefficients that hint for possibly genuine three-body nonfactorizable effects. Our hypothesis is further supported by the examination of D+s→K+K+π− decays, where we achieve a description in overall good agreement with data. 2023-12-04T11:10:15Z 2023-12-04T11:10:15Z 2023-11-06 journal article R.
