Kaonic hydrogen versus the K-p low-energy data

We present an exact solution to the K--proton bound-state problem formulated in the momentum space. The 1s level characteristics of the kaonic hydrogen are computed simultaneously with the available low-energy K - p data. In the strong-interaction sector the meson-baryon interactions are described by means of an effective (chirally motivated) separable potential and its parameters are fitted to the experimental data.
