Measurement of Cosmic Ray spectrum and Anisotropy with ARGO-YBJ

Abstract

In this paper we report on the observation of the anisotropy of cosmic ray arrival direction at different angular scales with ARGO-YBJ. Evidence of new few-degree excesses throughout the sky region 195${}^{\circ }\le$ R.A. $\le$ 315${}^{\circ }$ is presented for the first time. We report also on the measurement of the light-component (p+He) spectrum of primary cosmic rays in the range 5 - 200 TeV.
