23 Jan 2015 | | Abstract: | The AMADEUS experiment aims to provide unique quality data of $K^-$ 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 $Lambda(1405)$ 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. AMADEUS takes advantage of the
DA$Phi$NE 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. During the
second half of 2012 a successful data taking was performed with a dedicated
pure carbon target implemented in the central region of KLOE, providing a high
statistic sample of pure at-rest $K^-$ nuclear interactions. For the future
dedicated setups involving cryogenic gaseous targets are under preparation. | | Source: | arXiv, 1501.5781 | | Services: | Forum | Review | PDF | Favorites | |
