Several independent analyzes of Fermi-LAT results found evidences of a spatial dependence of the cosmic ray (CR) proton spectral index which is not accounted for in conventional models of CR transport in the Galaxy. Moreover, several CR experiments have established the presence of a CR spectral hardening above few hundred GeV. We show that these results may have a relevant impact on the gamma ... More
