摘要：

We have performed new fits of our chirally motivated coupled-channels model for meson-baryon interactions and discussed the impact of the SIDDHARTA measurement on the (K) over barN amplitudes in the free space and in nuclear medium. The kaon-nucleon amplitudes generated by the model are fully consistent with our earlier studies that used the older kaonic hydrogen data by the DEAR collaboration. The subthreshold energy dependence of the in-medium (K) over barN amplitudes plays a crucial role in (K) over bar -nuclear applications.
