Phenomenology of future neutrino experiments with large Theta(13)

Abstract
The question "how small is the lepton mixing angle θ_{13}?" had a convincing answer in a surprisingly short time, θ_{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 θ_{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 θ_{13} makes determination of the mass hierarchy easier. It stimulates to invent new ideas and necessitates quantitative reexamination of practical ways to explore it. (2) However, large θ_{13} does not quite make CP measurement easier so that we do need a "guaranteeing machine" to measure CP phase δ.
