This review covers the modern era of experimental kaonic atom studies, encompassing 20
years of activity, defined by breakthroughs in technological developments which allowed …

Kaonic atoms are an extremely efficient tool to investigate the strong interaction at the low
energy Frontier, since they provide direct access to the K− N interaction at threshold …

The K¯ N system at threshold is a sensitive testing ground for low energy QCD, especially
for the explicit chiral symmetry breaking. Therefore, we have measured the K-series X-rays …

We have measured the 3 d→ 2 p transition x rays of kaonic He 3 and He 4 atoms using
superconducting transition-edge-sensor microcalorimeters with an energy resolution better …

The kaonic helium-4 3d→ 2p X-ray transition was measured in a gaseous target, where
Compton scattering in helium is negligible. The X-rays were detected with large-area Silicon …

The SIDDHARTINO experiment at the DAΦNE collider of INFN-LNF, the pilot run for the
SIDDHARTA-2 experiment which aims to perform the measurement of kaonic deuterium …

The first observation of the kaonic 3He 3d→ 2p transition was made, using slow K− mesons
stopped in a gaseous 3He target. The kaonic atom X-rays were detected with large-area …

The SIDDHARTA-2 experiment at the DAΦNE collider aims to perform the first kaonic
deuterium x-ray transitions to the fundamental level measurement, with a systematic error at …

Abstract The VIolation of Pauli exclusion principle-2 experiment, or VIP-2 experiment, at the
Laboratori Nazionali del Gran Sasso searches for X-rays from copper atomic transitions that …

We present the analysis of K− absorption processes on He 4 leading to Λ π− final states,
measured with the KLOE spectrometer at the DAΦNE e+ e− collider and extract, for the first …
