Abstract

In this paper, we study the combined sensitivity of T2K-II and NOvA, the world leading long-baseline neutrino oscillation experiments, to CP violation in lepton sector. By operating until the year 2026, T2K-II is expected to collect a total exposure of \(20 \times 10^{21}\) protons-on-target. Meanwhile, NO$\nu$A experiment plan to expend the run up to 2024. By combining T2K-II and NO\(\nu\)A with an ultimate constraint from reactor, the sensitivity to CP-violation is expected to exceed $4\sigma$ C.L. It is also pointed out that by reducing the systematic uncertainties of both T2K-II and NO$\nu$A to a level of  2\%, the sensitivity to CP-violation will significantly increase with a discovery possibility at 5$\sigma$ C.L. significance for a particular range of true \(\delta_{CP}\).
