The semi-Hooperon: Gamma-ray and anti-proton excesses in the Galactic Center
A puzzling excess in gamma-rays at GeV energies has been observed in the center of our galaxy using Fermi-LAT data. Its origin is still unknown, but it is well fitted by Weakly Interacting Massive Particles (WIMPs) annihilations into quarks with a cross section around 10â26Â cm3sâ1 with masses of 20...
