Kaon-nuclei interaction studies at low energies (the AMADEUS project)

TL;DR

The AMADEUS project investigates low-energy kaon interactions with nuclei at the DAΦNE collider, focusing on deeply bound states, the \\Lambda(1405) resonance, and cross sections on light nuclei, using a specialized setup within the KLOE detector.

Contribution

This study introduces a dedicated experimental setup at DAΦNE for precise measurements of low-energy kaon-nuclei interactions, including bound states and resonance behavior.

Findings

Measurement of K- on light nuclei cross sections below 100 MeV/c.

First experimental investigation of deeply bound kaonic nuclear states.

Insights into the nature of the \\Lambda(1405) in nuclear matter.

Abstract

The AMADEUS experiment aims to perform dedicated precision studies in the sector of low-energy kaon-nuclei interaction at the DA\Phi NE collider at LNF-INFN. In particular the experiment plans to perform measurements of the debated deeply bound kaonic nuclear states (by stopping kaons in cryogenic gaseous targets 3He and 4He) to explore the nature of the \Lambda(1405) in nuclear environment and to measure the cross section of K- on light nuclei, for K- momentum lower than 100 MeV/c. The AMADEUS dedicated setup will be installed in the central region of the KLOE detector.
