Neutrino Experiments

Recently it is advocated that high intensity and low energy (Eν~2 GeV ) neutrino beams should be built to probe the (13) mixing angle ϕ to a level of a few parts in 104. Experiments using such beams will have better signal-to-background ratio in searches for νμ→νe oscillations. We propose that such experiments can also determine the sign of Δ31 even if the beam consists of neutrinos only. By measuring the νμ→νe transitions in two different energy ranges, the effects due to propagation of neutrinos through earth's crust can be isolated and the sign of Δ31 can be determined. If the sensitivity of an experiment to ϕ is ε, then the same experiment is automatically sensitive to matter effects and the sign of Δ31 for values of ϕ≥2ε.

Neutrino physics has come a long way and made great strides in the past decades. We discuss the prospects of what more can be learned in this field in the forthcoming neutrino oscillation facilities. We will mostly focus on the potential of the long-baseline experiments and the atmospheric neutrino experiments. Sensitivity of these experiments to standard neutrino oscillation parameters will be presented. We will also discuss the prospects of new physics searches at these facilities.

Best Fit

The long baseline neutrino experiments, T2K and NO[Formula: see text]A, have taken significant amount of data in each of the four channels: (a) [Formula: see text] disappearance, (b) [Formula: see text] disappearance, (c) [Formula: see text] appearance, and (d) [Formula: see text] appearance. There is a mild tension between the disappearance and the appearance data sets of T2K. A more serious tension exists between the [Formula: see text] appearance data of T2K and the [Formula: see text] appearance data of NO[Formula: see text]A. This tension is significant enough that T2K rules out the best-fit point of NO[Formula: see text]A at 95% confidence level, whereas, NO[Formula: see text]A rules out T2K best-fit point at 90% confidence level. We explain the reason why these tensions arise. We also do a combined fit of T2K and NO[Formula: see text]A data and comment on the results of this fit.
