Implication of a large \theta_13 for the Tokai to Kamioka and Korea setup

In this paper, I present the implications of the large value of \theta_13 on the Tokai to Kamioka and Korea setup (T2KK). I study the sensitivity of T2KK when using a 750 kW beam (the design luminosity of T2K planned to be achieved by 2017) and a potential 1.66 MW upgraded beam. In addition I compare the capability of the T2KK setup with the T2HK letter of intent.
