Belle CP violation in b to sqq and uud processes
  We report the analysis of time-dependent CP violation in neutral B meson system using a data sample corresponding to 140fb-1 collected by Belle detector and KEKB e+e- collider. One B meson decaying into CP eigenstate is fully reconstructed and the accompanying B meson flavor is identified by its decay products. The CP violation parameters are determined from the distribution of proper time intervals between the two B decays. Here we cover measurements of CP violation in b to uud and b to sq \bar{q$ processes.
