| Research Abstract |
CP violating phase is the unique unknown quantity among the lepton flavor mixing parameters. Given precision measurement of theta13 by the reactor measurement, we have investigated the sensitivity to the Kobayashi-Maskawa type lepton CP phase which can be reached by T2K (in Japan) or NOVA (in USA) experiments alone, and when they are combined. We used a reliable analysis code written with kind help of Masashi Yokoyama (T2K collaborator) and the results were presented with use of the newly proposed "CP exclusion fraction" by us. Assuming the operation of 10 years of each experiment, it was shown that T2K is able to exclude about a half of CP phase space at 90% CL, while NOVA's sensitivity is slightly less. Complementarity between T2K and NOVA experiments is also illuminated.
