Proton, anti Proton annihilation help!

  1. Apr 21, 2012 #1
    I have been told when a proton and anti proton annihilate only the one up and one anti up quark destroyed forming ∏+ and ∏- measons. I dont understand how both protons are not fully annihilated?

    anti proton has:
    anti up, anti up and anti down quarks
    proton has:
    up, up down quarks

    Any help would be appriciated. :)

    There are a number of channels in which this reaction can proceed.

    I found the following referenc where baryon-antibaryon annihilation dynamics is discussed. You may follow other references from there:
