Abstract

In this talk I have raised the question of how the future discovery of leptonic CP violation can be made robust even at accepting the rather large current experimental uncertainties in our knowledges of neutrino propagation in matter. To make progress toward answering the difficult question, I listed ways to proceed: (1) Obtain tighter constraints on the MSW theory by testing it by various neutrino experiments. (2) Measure the matter effect in situ, namely within the experiment for discovering CP violation itself. (3) Uncover leptonic CP violation in a matter effect free environment. I also reported a step made toward the above point (2) by taking neutrino factory as a concrete setting; An accurate in situ measurement of the matter effect looks promising.
