Low momentum K− (pK≃ 127 MeV/c) produced at the DAΦNE collider are impinged on a Carbon target within the KLOE detector and the two and three nucleon absorption processes are disentangled by comparing the experimental data to phenomenological calculations. The Λp spectra are entirely interpreted in terms of K− multi-nucleon absorption processes; the possible contribution of a K−pp bound state is demonstrated to overlap with the two nucleon capture process, its absolute yield thus resulting indistinguishable.application/pdfengcc-by (c) Grande, R. del et al., 2019http://creativecommons.org/licenses/by/3.0/esEstructura nuclearKaonsNuclear structureKaonsinfo:eu-repo/semantics/article6872002019-03-05info:eu-repo/semantics/openAccess
