Title: Quantum mechanics of neutrino detectors determine coherence and phases in oscillation experiments.

Abstract

The apparent symmetry between energy and momentum found in all covariant descriptions of neutrino oscillations is destroyed in the neutrino detector, a quantum mechanical system described by a density matrix diagonal in energy but not in momentum. The off diagonal matrix elements between states of different momenta and the same energy produce the coherence and interference between mass eigenstates having the same energy and different momenta that produce oscillations.

  • The effect of quantum mechanics violation due to quantum gravity on neutrino oscillation is investigated. It is found that the mechanism introduced by Ellis, Hagelin, Nanopoulos, and Srednicki through the modification of the Liouville equation can affect neutrino oscillation behavior and may be taken as a new solution of the solar neutrino problem. {copyright} {ital 1997} {ital The American Physical Society}
  • We try to understand and to develop some of the basic quantum mechanics of neutrino oscillation. First, we observe that measurements which identify the physical neutrino (mass eigenstate) involved in each event of an experiment destroy any oscillation pattern. We explain how these measurements do that. Then, we construct a wave-packet treatment of neutrino oscillation. We find that it gives the same results as the standard treatment. Next, we estimate the distance a beam must travel before its different physical neutrinos, which have different speeds, will stop interfering with each other. Finally, we consider the possibility of observing the differencemore » in the arrival times of the various physical neutrinos at a given point.« less
  • The dynamics of a driven spin-boson model is studied by means of the perturbation approach based on a unitary transformation. Analytical expressions for the population difference and the coherence of the two state system are obtained. The results show that for weak driving, the population difference displays damping coherent oscillation and/or damping quantum beat, depending on the initial preparation. The coherence exhibits damped oscillation with Rabi frequency. When driving is strong enough, the population difference exhibits undamped large-amplitude coherent oscillation. In addition, our theory leads to correct results in two limiting cases: without dissipation and without driving field.
  • We study the coherence condition for a neutrino to keep coherence between the effective mass eigenstates in the presence of matter and examine whether or not resonant neutrino oscillation (RNO) happens in the cases of solar and SN 1987A neutrinos. As a result, it becomes evident that RNO is possible in the solar-neutrino case but impossible in the SN 1987A neutrino case.
  • There is a growing interest in very long baseline neutrino oscillation experimentation using an accelerator produced neutrino beam as a machinery to probe the last three unmeasured neutrino oscillation parameters: the mixing angle {theta}{sub 13}, the possible CP violating phase {delta}{sub CP} and the mass hierarchy, namely, the sign of {Delta}m{sub 32}{sup 2}. Water Cherenkov detectors such as IMB, Kamiokande and Super-Kamiokande have shown to be very successful at detecting neutrino interactions. Scaling up this technology may continue to provide the required performance for the next generation of experiments. This report presents the latest effort to demonstrate that a nextmore » generation (>100 kton) water Cherenkov detector can be used effectively for the rather difficult task of detecting v{sub e}s from the neutrino oscillation v{sub {mu}} {yields} v{sub e} despite the large expected potential background resulting from {pi}{sup 0}s produced via neutral current interactions.« less
