New strong coupled-channels (K) over barN-pi Sigma potential, reproducing all existing experimental data and suitable for using in an accurate few-body calculations, is constructed. Isospin breaking effects of direct inclusion of the Coulomb interaction and using of physical masses in calculations are investigated. The 1s level shift and width of kaonic hydrogen, consistent with the scattering data, was obtained and the corresponding exact strong K(-)p scattering length was calculated. One- and two-pole form of Lambda(1405) resonance was considered.
