Antimatter - Antimatter interaction

Author: Daniel L. Miller

I’m asking whether interaction between identical particles is precisely matching interaction of identical antiparticles? Identical means that these particles cannot be distinguished upon exchange; they should have same charge, spin, spin projection, parity, quark flavor, and color, isospin etc. For example two up-quarks forming proton have different color. Therefore system has no symmetry with respect to exchange of these quarks and their interaction is not interesting. This explains why we see matching between proton and antiproton e/m ratio with high accuracy.

In other words, I'm asking to test commutation between the charge conjugation and exchange of indistinguishable particles. The experiment must compare interaction between 2 indistinguishable particles and compare the crossection with interaction between 2 indistinguishable antiparticles. I think in next few years anti-hydrogen molecule will be produced; then we will learn from S=0 to S=1 transition whether antimatter-antimatter interaction is matching matter-matter interaction.
