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.
