AbstractWe report angular correlation function (ACF) of Lyman Break Galaxies (LBGs) with unprecedented statistical quality from a sample of 16,920 galaxies at z=4 detected in the 1 deg^2 field of the Subaru/XMM-Newton Deep Field. The ACF significantly departs from a power law, and shows an excess on small scale. Particularly, the ACF of LBGs with i’<27.5 have a clear break between the small and large-scale regimes at the angular separation of ~7’’ whose projected length corresponds to the virial radius of dark halos with a mass of 10^{11-12} Mo, indicating multiple LBGs residing in a single dark halo. Both on small (2’’
