29. Is there place for strangeness in the Universe? Kaonic atoms studies at the DAFNE collider with advanced X-ray detectors

Dr Catalina Oana Curceanu (LNF)

I shall present a series of experiments performed during the last two decades at the DAFNE collider in Frascati devoted to the measurement of kaonic atoms using advanced X-ray detectors. The detectors which were used for these studies range from Charged Coupled Devices to two versions of spectroscopic Silicon Detectors. Combining the excellent quality kaon beam delivered by the DANE collider...

8. Past experiments and possible future experiments with high resolution X-ray detectors

The application of Gamma and X-ray detectors in exotic atom research has already a quite long history. On the one hand spectroscopy was used to study high Z kaonic atoms, low Z atoms recently by SIDDHARTA and last but not least to extract the up-to-now much precise masses of the charged kaon and the sigma, on the other hand the dynamics of processes in higher quantum states of exotic atoms...

11. X-ray measurements at J-PARC – a general overview

Mr Johann Zmeskal (SMI)

The antikaon-nucleon interaction close to threshold provides crucial information on the interplay between spontaneous and explicit chiral symmetry breaking in low-energy QCD. In this context, the importance of kaonic atom X-ray spectroscopy has been well recognized and were performed at KEK and J-PARC (Japan) and DAFNE (Italy) during the last 3 decades. At J-PARC there are now two experiments...
