“…We developed a precise method of computing the meson-nuclear bound states in momentum space. The method was already applied to pionic atoms [24] and its multichannel version was used to calculate the 1s level characteristics of pionic hydrogen [25]. Here we just remark that our approach is based on the construction of the Jost matrix and involves the solution of the Lippman-Schwinger equation for the transition amplitudes between various channels.…”

The effective separable meson-baryon potentials are constructed to match the equivalent chiral amplitudes up to the second order in external meson momenta. We fit the model parameters (low energy constants) to the threshold and low energy K − p data. In the process, the K − -proton bound state problem is solved exactly in the momentum space and the 1s level characteristics of the kaonic hydrogen are computed simultaneously with the available low energy K − p cross sections. The model is also used to describe the πΣ mass spectrum and the energy dependence of the K − n amplitude.

“…Our approach to solving the meson-nuclear bound state problem in the presence of multiple coupled channels was given in Ref. [1]. Here we just remark that the method is based on the construction of the Jost matrix and involves the solution of the Lippman-Schwinger equation for the transition amplitudes between various channels.…”

“…We developed a precise method of computing the mesonnuclear bound states in momentum space. The method was already applied to pionic atoms and its multichannel version was used to calculate the 1s level characteristics of pionic hydrogen [1]. In the present work we aim at simultaneous description of both the 1s level kaonic bound state and the available experimental data for the K − p initiated processes.…”

Abstract. 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.
