Investigation of the low-energy K− hadronic interactions with light nuclei by AMADEUS

Abstract

The aim of the AMADEUS collaboration is to provide new experimental constraints to the antikaon-nucleon ([Formula: see text]) strong interaction in the regime of nonperturbative QCD, investigating the low-energy [Formula: see text] hadronic interactions with light nuclei like H, 4He, 9Be and [Formula: see text]C. The unique low-momentum kaon beam produced at the DA[Formula: see text]NE collider is ideal to study [Formula: see text] nuclear captures, both at-rest and in-flight. The large acceptance KLOE detector, used as an active target, allows to achieve excellent position and momentum resolutions. In this work, a brief description of recent AMADEUS results is presented.

A review of the low-energy K−-nucleus/nuclei interactions with light nuclei AMADEUS investigations

“…The AMADEUS (Anti-kaonic Matter At DAΦNE: An Experiment with Unraveling Spectroscopy) Collaboration performed research of the low-energy K − -nucleon/nuclei interactions in light nuclear targets for over a decade [1][2][3]. The primary objective of these studies is an investigation of the poorly known Λ(1405) resonance and a deeper understanding of the K − single-and multi-nucleon absorption processes, both at-rest and in-flight, including the possible formation of kaonic bound states.…”
