12. Research objectives in detail • Determination of the antikaon-nucleon scattering lengths using data from kaonic atom x-ray spectroscopy (kaonic hydrogen Lyman spectrum) with new technology followed by theoretical extraction and interpretation. • Precision X-ray spectroscopy of kaonic atoms with light nuclei, such as kaonic3He and 4He for determination of the antikaon-nucleus interaction including its theoretical interpretation. • Further developments and applications of theoretical methods: chiral perturbation theory, effective field theory with strangeness, chiral SU(3) dynamics with coupled channels, antikaon-nuclear few-body theory; comparisons with data from high-precision experiments. And last but not least • Search for deeply bound antikaonic nuclear states using various reactions and fully exclusive determination of the reaction and decay products. ECT* Meeting Trento 2010

13. Theory Task T1 • Derivation of effective antikaon-nucleon interaction from chiral SU(3) coupled-channel dynamics significantly different results than local potential approach, consequences for kaonic bound nuclear systems. • Variational calculations of antikaon-nuclear quasibound states based on chiral SU(3) dynamics, binding energy of K-pp 20-40 MeV, width 50 MeV. • Theoretical studies of kaonicquasibound states in nuclei taking into account Λ(1405) and Σ(1385) resonances.
