==Key Stage 5==
===Meaning===
A '''π-meson''' is a type of [[meson]] which has a [[strangeness]] of zero.

===About π-mesons===
''NB: You do not need to memorise the exact composition of a given '''π-meson'''. However, you should be able to determine a possible [[quark]] composition given the [[Electrical Charge|charge]] of the [[meson]] and by remembering the properties of the [[up-quark]], [[down-quark]].''
: '''π-meson''' may consist of:
:*Up-antidown [[quark]] pair (π+).
:*Down-antiup [[quark]] pair (π-).
:*Up-antiup [[quark]] pair (π0).
:*Down-antidown [[quark]] pair (π0).
:*Strange-antistrange [[quark]] pair (π0).
