Description
Strange exotic atoms, in which a kaon (or a Sigma minus) replaces an
electron in orbit, offer a precision window into low-energy QCD,
high-precision QED and possible new physics studies.
Recent advances at DAΦNE (SIDDHARTA-2) and J-PARC are enabling
high-accuracy X-ray spectroscopy of kaonic atoms, such as hydrogen,
deuterium, and of many other light-to-heavy exotic atoms.
Proposals as EXKALIBUR, based on next-generation SDDs, on fast-timing CZT
detectors, on high-precision HPGe, as well as TES detection systems used
in Japan (for example for muonic atoms) open the path to sub-eV precision
and a broader program on strange atomic systems.
This contribution outlines future opportunities and a partway towards
coordinated strategies at DAΦNE and J-PARC, highlighting their
complementary roles in advancing the physics of fundamental interactions
studies with strange exotic atoms.
