Are pions produced in pairs?

  1. Jun 4, 2017 #1
    I thought only strange particles were produced in pairs via the strong interaction, however in my text book it states 'kaons, like pions are produced in pairs via the strong interaction'.

    Can particles that are not strange also be produced in this way?

    Pions can be produced in pairs, they can also be produced as single particles.
    Kaons are always* produced in pairs by the strong interaction.

    *unless some other particle with a strange quark is produced.
