SUMMARY
The strong interaction in pionic hydrogen is attractive due to the negative charge of the pion replacing the electron, which facilitates attraction to the proton. In contrast, kaonic hydrogen exhibits a repulsive strong interaction because the negatively charged kaon orbits the hydrogen atom, necessitating repulsion to maintain its orbit. This phenomenon is linked to sub-threshold resonances, which play a critical role in the interaction dynamics of these exotic atoms.
