Estimating QCD uncertainties in Monte Carlo event generators for gamma-ray dark matter searches
Estimating QCD uncertainties in Monte Carlo event generators for gamma-ray dark matter searches
Motivated by the recent galactic center gamma-ray excess identified in the Fermi-LAT data, we perform a detailed study of QCD fragmentation uncertainties in the modeling of the energy spectra of gamma-rays from Dark-Matter (DM) annihilation. When Dark-Matter particles annihilate to coloured final states, either directly or via decays such as …
