Kaonic atoms measure the antikaon-nucleus interaction at almost zero relative energy, allowing one to determine basic low-energy quantum chromodynamics (QCD) quantities, namely, antikaon-nucleon ( K ¯ N) scattering lengths. The latter are important for extracting sigma terms which built on symmetry breaking part of Hamiltonian, thereby providing a chiral and SU(3) symmetries breaking. After discussing their relations kaonic atoms, we describe most precise measurement in literature hydrogen,...
Kaonic atoms are an extremely efficient tool to investigate the strong interaction at low energy Frontier, since they provide direct access K − N threshold, eliminating necessity for extrapolation, unlike in case of scattering experiments.
