==Key Stage 5==
===Meaning===
A '''K-meson''' is a type of [[meson]] which has a [[strangeness]] of +1 or -1.
===About K-mesons===
''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 [[Electrical Charge|charge]] and [[strangeness]] of the [[meson]] and by remembering the properties of the [[up-quark]], [[down-quark]] and [[strange-quark]].''
: '''K-meson''' may consist of:
:*Up-antistrange [[quark]] pair (<math>K^+</math>).
:*Down-antistrange [[quark]] pair (<math>K^0</math>).
:*Strange-antiup [[quark]] pair (<math>K^-</math>).
:*Strange-antidown [[quark]] pair (<math>\bar{K}^-</math>).
