Abstract content

Since the the observation of the $\nu_\mu \rightarrow \nu_e$ appearance channel by T2K and others, neutrino experiments have refocused on precision measurements. Previous generations of experiments sought simply to detect oscillations in a particular channel, which is optimally achieved with a baseline and energy tuned as close as possible to the first maximum of the oscillation signature. But in the precision era this is not optimal for all measurements.

In this poster we highlight the benefits of placing a detector at a baseline that cover the second oscillation maximum, such as could be achieved by a Korean detector site in the J-PARC neutrino beam. This has non-obvious effects and benefits for the measurement of CP phase; the manifestation of matter effects leading to a determination of the mass hierarchy; and the ability to distinguish deviations from the model, be they systematic errors or departures from the PMNS mixing paradigm.
