    1. The problem statement, all variables and given/known data


    Q)

    1]Neutral pion decays into 2 photons which then decay into electron-positron pairs.

    What would the feynman diagram look like?

    2] Why is this decay of the neutral pion difficult to identify in bumble chambers?


    2. Relevant equations

    feynman diagram


    3. The attempt at a solution


    1]neutral pion enters feynman diagram with arrow point in, then separating into 2 photons show by squiggly lines. both of these photons then separate creatin the electron-positron annihilation shown by e- meeting the photon and e+ meeting the photon ???

    2]hard to detect as photons are invisible and only show up when interacting with as particle and can have gaps between their interactions like with the electron-positron shown here

    ???:confused:
