We start from an elementary production diagram, considered subleading in previous approaches, which cannot produce a final K-K+ pair at the tree level but which we show to be able to provide the strength of the decay through final meson-meson state interaction. The different meson-meson elementary productions are related through SU(3), and the final rescattering is implemented from a suitable implementation of unitary extensions of chiral perturbation theory, which generate dynamically the scalar resonances1 f(0)(980) and a(0)(980). We obtain a good agreement with recent experimental data from the LHCb Collaboration with a minimal freedom in the fit and show the dominance of the a(0)(980) contribution close to the threshold of the K-K+ spectrum.", optnote="WOS:000621332000004", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=4742), last updated on Mon, 22 Mar 2021 07:22:39 +0000", issn="2470-0010", doi="10.1103/PhysRevD.103.034020", opturl="https://arxiv.org/abs/2011.05185", opturl="https://doi.org/10.1103/PhysRevD.103.034020", language="English" }
