Investigating an Antimatter Imbalance in the Proton (IMAGE)
Caption
A proton contains 3 more quarks than antiquarks (large dots) & a sea containing an equal number of quarks & of antiquarks (small dots). When two protons collide, a quark & antiquark may annihilate to create a single photon that decays to a pair of muons.
