The K-1 (1270) resonance is dynamically generated through these interactions in coupled channels and influences the shape of the invariant mass distributions under consideration. We show how these shapes are affected by the K-1 (1270) double-pole structure to confront the results from our model with future experiments that might investigate the PV spectra in these decays.", optnote="WOS:000664520700018", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=4886), last updated on Mon, 19 Jul 2021 06:53:58 +0000", issn="2470-0010", doi="10.1103/PhysRevD.103.116019", opturl="https://arxiv.org/abs/2102.08402", opturl="https://doi.org/10.1103/PhysRevD.103.116019", language="English" }
