Description
The data recorded by ARGO-YBJ in more than 5 years have been analyzed todetermine the diffuse gamma ray emission from the Galactic plane. The spatial distribution of the diffuse gamma rays and their energy spectra at Galactic longitudes 25^o < l <100^o o and Galactic latitudes |b|<5^o have been studied. The regions with 40^o< l <100^o and 65^o < l <85^o have been focused, where Milagro observed an excess with respect to the predictions of current models. The energy range investigated covers from ~350 GeV to ~2TeV, connecting the region explored by Fermi-LAT with the multi-TeV
energies studied by Milagro. Great care has been taken in masking the TeV
point sources observed by ARGO-YBJ and other experiments. Our results are
consistent with the predictions of the Fermi model and do not show any
excess as observed by Milagro.
