Neutrino Superbeam Scenarios at the Peak

Abstract

We discuss options for U.S. long baseline neutrino experiments using upgraded conventional neutrino beams, assuming $L/E_{\hat{I}}½$ is chosen to be near the peak of the leading oscillation. We find that for L = 1290 km (FNAL-Homestake) or 1770 km (FNAL-Carlsbad, or BNL-Soudan) it is possible to simultaneously have good ${\sin }^{2}2\hat{I}{¸}_{13}$ reach and sgn($\hat{I}´m_{31}^2$) determination, and possibly sizeable $\ddot{I}„$ rates and some $\hat{I}´$ sensitivity.
