Precision Neutrino Oscillation Measurements using Simultaneous High-Power, Low-Energy Project-X Beams
Abstract
The first phase of the long-baseline neutrino experiment, LBNE10, will use a broadband, high-energy neutrino beam with a 10-kt liquid argon TPC at 1300 km to study neutrino oscillation. In this paper, we describe potential upgrades to LBNE10 that use Project X to produce high-intensity, low-energy neutrino beams. Simultaneous, high-power operation of 8- and 60-GeV beams with a 200-kt water Cerenkov detector would provide sensitivity to numu to nue oscillations at the second oscillation maximum. We find that with ten years of data, it would be possible to measure sin2(2theta13) with precision comparable to that expected from reactor antineutrino disappearance and to measure the value of the CP phase, deltaCP, with an uncertainty of (5-10) degrees.
