Looking for the Gluon Condensation Signature in Protons Using the Earth-limb Gamma-Ray Spectra
Abstract
A new type of gamma-ray spectrum is predicted in a general hadronic framework by taking into account gluon condensation (GC) effects in proton. The result presents a power law with a sharp break in the gamma-ray spectra at the TeV band. We suggest probing this GC signature in Earth-limb gamma-ray spectra using the Dark Matter Particle Explorer and the Calorimetric Electron Telescope in orbit.
