2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/191729We 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.6 pages, 1 figure, ver2: minor text changes made prior to journal publicationHigh Energy Physics - PhenomenologyKaonic hydrogen versus the $K^{-}p$ low energy datatext
