地球物质密度测量与MSW理论检验

Measuring Earth Matter Density and Testing the MSW Theory

Hisakazu Minakata

摘要:

在这次演讲中,我提出了这样一个问题:即使在我们对中微子在物质中传播的认识中存在相当大的当前实验不确定性的情况下,如何使将来对轻子CP破坏的发现变得可靠。为了在回答这个难题上取得进展,我列出了一些方法:(1)通过各种中微子实验来检验MSW理论,从而使它得到更严格的约束。(2)现场测量物质效应,即在实验中发现CP破坏本身。(3)在无物质效应环境中揭示轻子CP破坏。我还报道了以中微子工厂为具体背景,朝着上述(2)点迈出的一步;对物质效应的精确原位测量看来是有希望的。

英文摘要:

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.
