The pi-meson (π0)

  1. Oct 10, 2015 #1
    1. The problem statement, all variables and given/known data
    How does the pi-meson (π0) work without annihilating itself?

    2. Relevant equations
    |π01/√2 〉- {|uu − |dd}

    u= anti-upquark
    d= anti-downquark

    3. The attempt at a solution
    I do understand that it is a superposition, but why does it work when it is a partice with its own anti.particle?

    What do you mean by "work". The pi mesons are all unstable particles which decay with well known half-lives.
