“…When extracting the Λ(1405) shape from K − induced reactions in light nuclear targets (see for example [23]) the hyperon-pion spectroscopy is influenced by the energy threshold, imposed by the last nucleon binding energy. The m Σπ invariant mass threshold is about 1412 MeV and 1416 MeV, for K − capture at-rest in 4 He and 12 C respectively, thus the K − absorption at-rest is not sensitive to the high mass pole predicted by chiral unitary models.…”

Abstract. The AMADEUS collaboration aims to provide unique quality results from K − hadronic interactions in light nuclear targets, in order to solve fundamental open questions in the non-perturbative strangeness QCD sector, like the controversial nature of the Λ(1405) state, the yield of hyperon formation below threshold, the yield and shape of multi-nucleon K − absorption, processes which are intimately connected to the possible existence of exotic antikaon multi-nucleon clusters and to the role of strangeness in neutron stars. AMADEUS takes advantage of the DAΦNE collider, which provides a unique source of monochromatic low-momentum kaons and exploits the KLOE detector as an active target, in order to obtain excellent acceptance and resolution data for K − nuclear capture on H, 4 He, 9 Be and 12 C, both at-rest and in-flight.

“…However, there has been no clear indication of the Λ(1405) formation in the 3 He(K − , n)X reaction at 1 GeV/c, so far. In the case of the (K − stop , π − ) reaction like in the FINUDA experiment, the Λ(1405) has played an important role [15] in producing Σπ's in the final state rather than Λπ.…”
