Multi-scale TeV cosmic-ray anisotropy observed with the ARGO-YBJ experiment

The distribution of the cosmic-ray arrival direction provides essential information about the source distribution, the propagation medium and the diffusive process that primaries undergo. To the current knowledge of the local interstellar medium, cosmic rays in the rigidity range 10(12)-10(13) V are re-accelerated within few hundreds of astronomic units, what makes the TeV anisotropy an important probe to investigate the outer space until that horizon. We report the observation of anisotropy in the TeV cosmic-ray arrival direction measured with the ARGO-YBJ experiment, at angular scales in the range 10 degrees-180 degrees and with intensity 10(-4)-10(-3). Findings of other experiments are confirmed and new details on the cosmic-ray distribution in the declination range -10 degrees-70 degrees are given.
