Phenomenology of future neutrino experiments with large Theta(13)

Understand

The question "how small is the lepton mixing angle \theta_{13}?" had a convincing answer in a surprisingly short time, \theta_{13} \simeq 9^{\circ}, a large value comparable to the Chooz limit.

• It defines a new epoch in the program of determining the lepton mixing parameters, opening the door to search for lepton CP violation of the Kobayashi-Maskawa-type.
• I discuss influences of the large value of \theta_{13} to search for CP violation and determination of the neutrino mass hierarchy, the remaining unknowns in the standard three-flavor mixing scheme of neutrinos.
• I emphasize the following two points: (1) Large \theta_{13} makes determination of the mass hierarchy easier.
