21 Apr 2017 | | Abstract: | The aim of AMADEUS is to provide unprecedented experimental information on
K$^-$ absorption in light nuclear targets, to face major open problems in
hadron nuclear physics in the strangeness sector, namely the nature of the
$Lambda$(1405), strongly related to the possible existence of kaonic nuclear
clusters, kaons and hyperon scattering cross sections on nucleons and nuclei.
These issues are fundamental for a better understanding of the non-perturbative
QCD in the strangeness sector.
AMADEUS step 0 deals with the analysis of the 2004-2005 KLOE collected data.
The interactions of the negative kaons produced by the DA$Phi$NE collider (a
unique source of monochromatic low-momentum kaons) with the materials of the
KLOE detector, used as active targets, provide samples of K$^-$ absorptions on
H, ${}^4$He, ${}^{9}$Be and ${}^{12}$C, both at-rest and in-flight. A second
step deals with the data from the implementation in the central region of the
KLOE detector of a pure graphite target, providing a high statistic sample of
K$^- , {}^{12}$C nuclear captures at rest. For the future a new setup, with
various dedicated gaseous and solid targets, is under preparation. | | Source: | arXiv, 1704.6562 | | Services: | Forum | Review | PDF | Favorites | |
