We show that the K- p produced only couples to Lambda* states, not Sigma* and that the pi Sigma state is only generated from final state interaction of (K) over barN and eta Lambda channels which are produced in a primary stage. This guarantees that the pi Sigma state is generated in isospin I=0 and we see that the invariant mass produces a clean signal for the Lambda(1405) of higher mass at 1420 MeV. We also study the eta(c)p final state interaction, which is driven by the excitation of a hidden charm resonance predicted before. We relate the strength of the different invariant mass distributions and find similar strengths that should be clearly visible in an ongoing LHCb experiment. In particular we predict that a clean peak should be seen for a hidden charm resonance that couples to the eta(c)p channel in the invariant eta(c)p mass distribution.", optnote="WOS:000423930700061", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3480), last updated on Wed, 21 Feb 2018 08:56:18 +0000", issn="0370-2693", doi="10.1016/j.physletb.2017.12.064", opturl="http://arxiv.org/abs/1711.01710", opturl="https://doi.org/10.1016/j.physletb.2017.12.064", archivePrefix="arXiv", eprint="1711.01710", language="English" }
