The Positron Fraction<br />
Fragmentation of the gauge bosons also produces positrons and<br />
antiprotons → Important consistency check, but may also produce<br />
interesting signatures<br />
Complicated antimatter propagation due to diffusion and energy loss<br />
→ loss of directional and spectral information<br />
The astrophysics of propagation involves many uncertainties about<br />
properties of the interstellar medium<br />
