Abstract
Combining ν oscillations at T2K or T2HK with \( \overline{\nu} \) oscillations from μ + decay at rest (DAR) allows a determination of the leptonic CP-violating phase δ. The degeneracies of this phase with θ 13 and θ 23 are broken and δ can be reliably distinguished from 180° − δ. We present the sensitivity to δ of T2(H)K together with a μ + DAR experiment using Super-K as a near detector and Hyper-K at the Tochibora site as a far detector.
