Key Stage 5
Meaning
A K-meson is a type of meson which has a strangeness of +1 or -1.
About K-mesons
- K-mesons decay via the weak interaction to produce π-mesons. In this case strangeness is not conserved.
NB: You do not need to memorise the exact composition of a given K-meson. However, you should be able to determine a possible quark composition given the charge and strangeness of the meson and by remembering the properties of the up-quark, down-quark and strange-quark.
