“…We have calculated the isospin-breaking corrections and the dispersive corrections to the energy level displacement of the ground state of kaonic hydrogen within the quantum field theoretic model of low-energy KN interactions developed in [3,5] (see also [24,25] and [35,36]). The isospin-breaking corrections are caused by the QCD isospin-breaking interaction, whereas the dispersive corrections are defined by the contribution of the transition K − p → Ko n → K − p to the S-wave amplitude of K − p scattering with the K0 n pair on-mass shell.…”

In the model of low-energyKN interactions near threshold (EPJA 21, 11 (2004); 25, 79 (2005)) we calculate isospin-breaking corrections to the energy level displacement of the ground state of kaonic hydrogen, investigated by Meißner, Raha and Rusetsky (EPJC 35, 349 (2004)) within the non-relativistic effective Lagrangian approach based on ChPT by Gasser and Leutwyler. Our results agree well with those by Meißner et al.. In addition we calculate the dispersive corrections, caused by the transition K − p →K 0 n → K − p with theK 0 n pair on-mass shell. We show also how hypothesis on the dominant role of theK 0 n-cusp for the S-wave amplitude of low-energy K − p scattering near threshold, used by Meißner et al., can be realized in our approach. The result agrees fully with that by Meißner et al..

“…where E H (n) ( q) = M 2 H (n) + q 2 and q are the energy and the momentum of hydrogen, M H (n) = m p + m + n is the mass of hydrogen and n is the binding energy of the nLstate, φ nLM L ( k) is the wavefunction of the nLM L -state in the momentum representation [9] (see also [12][13][14]).…”

We argue that due to isospin and U -spin invariance of strong low-energy interactions the S-wave scattering lengths a 0 0 and a 1 0 ofKN scattering with isospin I = 0 and I = 1 satisfy the low-energy theorem a 0 0 + 3a 1 0 = 0 valid to leading order in chiral expansion. In the model of strong low-energyKN interactions at threshold (EPJA 21,11 (2004)) we revisit the contribution of the Σ(1750) resonance, which does not saturate the low-energy theorem a 0 0 + 3a 1 0 = 0, and replace it by the baryon background with properties of an SU (3) octet. We calculate the S-wave scattering amplitudes of K − N and K − d scattering at threshold. We calculate the energy level displacements of the ground states of kaonic hydrogen and deuterium. The result obtained for kaonic hydrogen agrees well with recent experimental data by the DEAR Collaboration. We analyse the cross sections for elastic and inelastic K − p scattering for laboratory momenta 70 MeV/c < p K < 150 MeV/c of the incident K − meson. The theoretical results agree with the available experimental data within two standard deviations.
