Strong interaction in hadronic hydrogen atoms

  1. Mar 21, 2006 #1
    Hello,

    Does anyone know why in pionic hydrogen the strong interaction should be attractive whilst in kaonic hydrogen it is repulsive. I have heard it is something to do with a sub-threshold resonance but nothing more.

    Thanks

    In pionic hydrogen the negative charge "pion" replaces the negative "electron"--thus predict attraction--see this link:http://www.oeaw.ac.at/smi/research/pi-h.htm. However, in kaonic hydrogen the negative "kaon" is found orbiting the hydrogen atom and thus predict repulsion to maintain the orbit--see this link for details: http://en.wikipedia.org/wiki/Kaonic_hydrogen
