on behalf of the SIDDHARTA collaborationThe KN system at rest makes a sensitive testing ground for chiral SU(3) symmetry in QCD, especially for the explicit symmetry breaking induced by the relatively large mass of the strange quark. At the DAΦNE electron-positron collider of Laboratori Nazionali di Frascati we study kaonic atoms, taking advantage of the low-energy kaons from Φ-mesons decaying nearly at rest. The low-energy antikaon-nucleon interaction in kaonic hydrogen and kaonic deuterium can be investigated under favorable conditions. The DEAR (DAΦNE Exotic Atom Research) experiment at LNF delivered the most precise data on kaonic hydrogen up to now. DEAR and its follow-up experiment SIDDHARTA (Silicon Drift Detector for Hadronic Atom Research by Timing Application) are using X-ray spectroscopy of kaonic atoms to measure the strong interaction induced shift and width of the ground state. SID-DHARTA will be the first experiment on kaonic deuterium ever, and kaonic hydrogen will be remeasured with greatly improved precision. From the shift and width in K − p and K − d the isospin-dependent antikaon-nucleon scattering lengths can be determined, quantities essential as constraints for low-energy QCD.

“…± 30(syst.) eV (5) This measurement has triggered new interest from the theoretical groups working in the low-energy kaon-nucleon interaction field, and as well it is related to nonperturbative QCD tests [10][11][12][13][14][15][16][17].…”

“…Recently in Refs. [1]- [4] (see also [5]) we have proposed a phenomenological quantum field theoretic model for strong low-energyKN andKNN interactions at threshold for the analysis of the experimental data by the DEAR Collaboration Refs. [6,7] on the energy level displacement of the ground state of kaonic hydrogen According to the DGBTT formula [8], the energy level displacement of the ground state of kaonic hydrogen is related to the S-wave amplitude f K − p 0 (0) of elastic K − p scattering at threshold as…”

On the estimate of the σ (I=1) KN (0)-term value from the energy level shift of kaonic hydrogen in the ground state AbstractUsing the experimental data on the energy level shift of kaonic hydrogen in the ground state (the DEAR Collaboration, Phys. Rev. Lett. 94, 212302 (2005)) and the theoretical value of the energy level shift, calculated within the phenomenological quantum field theoretic approach to the description of strong low-energyKN and KN N interactions developed at Stefan Meyer Institut für subatomare Physik in Vienna, we estimate the value of the σ (I=1) KN (0)-term of low-energyKN scattering. We get σ (I=1) KN (0) = (433 ± 85) MeV. This testifies the absence of strange quarks in the proton structure.
