Resum

In this proceeding, we report the recent studies in charmless two-body decays from B factories and Belle II prospects on direct CP violation in charmless B decays. We present the first observation of the decay B 0 s → K 0K 0 using a dataset of 121.4 f b−1 collected at the ϒ(5S) resonance with the Belle detector. We also discuss the first evidence of B 0 → ηη. Being also related to direct CP asymmetry, we present a preliminary measurement of the branching fraction and CP asymmetry of B + → K +K −π + decays. Furthermore, we discuss the future prospects on the studies of direct CP violation in charmless B decays at the coming Belle II experiment.
