Measurement of Kaonic Hydrogen with Dear at DAΦNE and Future Perspectives
Abstract
The objective of the DEAR (DAΦNE Exotic Atom Research) and the coming SIDDHARTA (SIlicon Drift Detector for Hadronic Atom Research by Timing Application) experiments is an eV precision measurement of the Kα line shift and width, due to the strong interaction, in kaonic hydrogen and a similar measurement - the first one - in kaonic deuterium. The final aim is a precision determination of the antikaon-nucleon isospin dependent scattering lengths, which allows to better understand the chiral symmetry breaking scenario in the strangeness sector. DEAR has performed the most precise measurement up to now on kaonic hydrogen at the end of 2002. It is for the first time that the K-complex could be clearly identified. The obtained result is presented in this paper. An eV precision measurement of kaonic hydrogen and kaonic deuterium is foreseen in the framework of the newly started SIDDHARTA project, which continues the DEAR scientific line.
