- Abstract: After the discovery of Fermi bubbles and the excess of gamma-ray emission, the Galactic Center has received increasing attention with the aim to understand its role in the origin and acceleration of primary cosmic rays. Based on a diffusion/reacceleration model, we use the galprop software to solve the diffusion equation for the cosmic rays and compare the results with the cosmic-ray spectrum, motivated by the relationship between several energetic sources at the Galactic Center and the generated diffuse GeV-TeV gamma rays. We calculate the cosmic ray distribution, gamma-ray flux from the Galactic Center and explore its contribution on the spectrum and chemical composition of cosmic rays observed on Earth. We also discuss the effects of nuclei interactions with different interstellar gas models.
