Abstract: One of the fundamental properties of particles is their behavior under the CP (charge-parity) transformation and a violation of the CP symmetry may have an important connection to the observed baryon asymmetry in the Universe. In the lepton sector, the landmark discovery of non-zero 1-3 mixing angle by the Daya Bay experiment established the standard three-flavor oscillation picture of neutrinos and opened the door for a completely new and independent source of CP invariance violation in neutrino oscillation experiments. In the intensity frontier, the currently running and upcoming high-precision long-baseline neutrino oscillation experiments are the most promising avenues to observe a difference between neutrino and antineutrino transition probabilities - providing a smoking gun signature of leptonic CP violation. In this talk, after having an insightful discussion on the critical role of CP asymmetries in the appearance and disappearance channels, I will present in detail the capabilities of the next-generation long-baseline neutrino oscillation experiments DUNE and T2HK in isolation and combination to establish the leptonic CP violation at high confidence level. I will show how the possible complementarity among the on-axis DUNE and off-axis T2HK experiments can enhance the sensitivity towards leptonic CP violation by suppressing the parameter degeneracies.
