Beim Kaon (vielmehr: den Kaonen) handelt es sich um das leichteste Meson,  welches ein \"s\"-quark enth\u00e4lt. Damit sind folgende Kombinationen m\u00f6glich: \"K^0=|d\bar{s}\rangle\",  \"K^+=|u\bar{s}\rangle\",  \"\bar{K}^0=|\bar{d}s\rangle\",  \"\bar{K}^-=|\bar{u}s\rangle\". Die geladenen Kaonen haben eine Masse von 493 MeV, w\u00e4hrend die neutralen eine Masse von 497 MeV besitzen.<\/p>\n

Das Kaon besitzt mit \"1,2s eine relativ lange Lebensdauer. Der Zerfall kann nur \u00fcber die schwache Wechselwirkung erfolgen, da sie als einzige die Strangeness verletzt, dabei wird das s-Quark in das leichtere u-Quark umgewandelt, was nur mit einer geringen Wahrscheinlichkeit passiert (siehe CKM Matrix).<\/p>\n

Das Kaon war das Teilchen an dem man 1964 die CP-Verletzung nachgewiesen hat….<\/p>\n

Erzeugt werden Kaonen vornehmlich in der der H\u00f6henstrahlung durch die Streuung zwischen einem Proton und einem Pion:<\/p>\n\n\n\n\n
