3 3 Stefan Meyer Institute - short history P. Kienle, Director of "Institute for Medium Energy Physics“ (founded 1987) 2004: Renamed to Stefan Meyer Institute (SMI), Director E. Widmann Stefan Meyer first director of the „Institut für Radiumforschung“ – Founded 1910 – 1 st institute of Austrian Academy – Pioneer in radioactivity research – 2 nobel laureates (V. Hess, G. Hevesy) Nuppec Meeting, Vienna, March 13,

4 Exotic Atoms Nuppec Meeting, Vienna, March 13, Exotic atoms represent a bridge between atomic physics and nuclear/particle physics … and an unique laboratory precision experiments

5 5 Fundamental symmetry and interaction studies with exotic atoms Hadronic atoms (pionic, kaonic, antiprotonic atoms) highly excited states (optical transitions) pbar-He (atomcule) – spectroscopy, with QED  pbar properties, CPT low-lying states (xray transitions) – Strong interaction at low- energy (inaccessible in scattering experiments) shift and broadening by strong interaction Nuppec Meeting, Vienna, March 13, 2009

6 6 Research Areas Matter-antimatter asymmetry: CERN Antikaon-nucleon interaction: kaonic atoms and nuclei Antiprotons at FAIR Nuppec Meeting, Vienna, March 13, 2009

8 Antiproton Physics at CERN-AD ASACUSA Nuppec Meeting, Vienna, March 13, 20098

9 9 Antiprotonic helium Hyperfine structure – Precision microwave spectroscopy – antiproton magnetic moment, QED/CPT test Laser spectroscopy – antiproton mass & charge  QED/CPT test – 2-photon spectroscopy to increase precision Nuppec Meeting, Vienna, March 13, 2009

10 10 Antihydrogen ground-state hyperfine structure complementary to 1S-2S laser spectroscopy (ALPHA, ATRAP) – spin-spin interaction – direct CPT test measured in hydrogen to 10 −12 atomic beam method (Rabi) – no trapping, 100 K temperature is o.k. new recombination schemes needed – point source straight sextupoles, 4T pole field: efficiency ~10 −4 CPT test by comparison of hfs H vs. H Nuppec Meeting, Vienna, March 13, 2009

11 Antikaon-nucleon Interaction Nuppec Meeting, Vienna, March 13,

12 12 Kaonic Atom „puzzles“ K − 4 He (solved) and K − 3 He at J-PARC (scheduled) Nuppec Meeting, Vienna, March 13, 2009 DEAR/SIDDHARTA: K − p, K − d, K -4 He at LNF (running)  repulsive Δε 1s attractive  Kaonic hydrogen Kaonic helium ( 4 He)

13 Low-energy antikaon- nucleon interaction The low-energy kaon-nucleon interaction is neither simple nor well understood. Problems arise from the existence of resonances like the famous Λ*(1405) in the s wave (one pole/two pole structure?) In general the development of reliable theories suffers from the lack of precision data on the observables (e.g. shift/width of kaonic atoms) Nuppec Meeting, Vienna, March 13,

14 Low energy kaon-nucleon interaction K-p threshold data Sources of information on the s-wave interaction put constraints on theory: –Kaon-proton scattering data (old data, large errors) –πΣ mass spectrum –Threshold inelastic decay ratios –X-ray data of kaonic atoms (e.g. K - p, K - d) Reliable theory has to cope these informations Nuppec Meeting, Vienna, March 13, Most simple systems K - p, K - d (K -3,4 He) "kaonic hydrogen puzzle" solved (sign of strong interaction is negative, i.e. repulsive at threshold ) New precision experiments running/upcoming LNF, Precision - challenge for experiments Challenge for theory (extraction of scattering lengths, K-N sigma term)
