WebbWe discuss the structure of the nuclear force using a lagrangian derived from hadronization of a chiral quark and diquark model. A generalized trace log formula including meson and nucleon fields is expanded to the ord… WebbIn particle physics, a kaon (/ ˈ k eɪ. ɒ n /), also called a K meson and denoted K, is any of a group of four mesons distinguished by a quantum number called strangeness.In the quark model they are understood to be bound states of a strange quark (or antiquark) and an up or down antiquark (or quark).. Kaons have proved to be a copious source of information …
