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

TL;DR

This paper examines how a large b8_13 influences the sensitivity and capabilities of the T2KK neutrino experiment setup, comparing different beam powers and with the T2HK proposal.

Contribution

It provides an analysis of the impact of a large b8_13 on T2KK's sensitivity and compares its performance with T2HK, considering different beam powers.

Findings

Higher beam power improves sensitivity.

T2KK shows competitive performance with T2HK.

Large b8_13 enhances experimental sensitivity.

Abstract

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.
