Is the Large Uncertainty of ${δ}_{CP}$ Fundamentally Encoded in the Neutrino Quantum State?
feeds.aps.org · By Michela Ignoti, Claudia Frugiuele, Matteo G. A. Paris & Marco G. Genoni ·
The Brief
- The precise measurement of the leptonic CP-violating phase δCP remains a major open challenge in neutrino physics.
- Current experiments achieve only very limited accuracy in measuring δCP.
- The paper asks whether the large uncertainty in δCP is fundamentally encoded in the neutrino quantum state.
Why it matters
The study asks whether the large uncertainty in δCP reflects a fundamental limit tied to the neutrino quantum state, which bears on how precisely future experiments can measure leptonic CP violation.
