We study the angular correlation function of passive and star-forming galaxies at 0.2<z<1.0 in the COSMOS field as a function of stellar mass, in order to investigate the relationship between the stellar mass growth of galaxies and their DM halos. The clustering strength of star-forming galaxies strongly depends on stellar mass. On the other hand, passive galaxies are more strongly clustered than SF galaxies in all mass ranges, but their clustering strength weakly and inversely depends on<br>mass; passive galaxies with lower stellar mass are more strongly clustered than massive ones. We also found that the clustering of post-starburst galaxies is similarly strong. The quenching of star formation in these galaxies can be related with massive DM halo environment.
