Solar Neutrino measurements

Abstract

Abstract. A review of solar neutrino experiments is provided, including experimental measurements to date and proposed future measurements. Experiments to date have provided a clear determination that solar neutrinos are undergoing flavor transformation and that the dominant mechanism for this transformation is oscillation. The mixing parameters are well defined and limits are placed on subdominant modes. The measurements also provide strong confirmation of solar model calculations. New experiments under development will study neutrino oscillation parameters and sub-dominant modes with greater precision and will investigate solar fluxes further, concentrating primarily on the low energy pp,

Phenomenology of future neutrino experiments with large

“…Similarly, ∆m 2 21 and θ 12 are measured by the solar [18] and the Kam-LAND [19] experiments independently. In this sense, it is great that we were able to maintain double coverage of θ 13 determination by the reactor and the accelerator experiments.…”

Neutrino beams

“…Six independent parameters have to be experimentally measured: three mixing angles θ 12 , θ 13 , θ 23 , two mass-squared differences ∆m 2 12 , ∆m 2 23 , where ∆m 2 ij = m 2 i − m 2 j , and a CP violating phase δ. The solar neutrino measurements [1] and the KamLAND [2] long-baseline reactor experiment constrain the solar neutrino mixing angle and mass splitting to 0.32 < tan 2 θ 12 < 0.55 and 6 · 10 −5 < |∆m 2 12 | < 9 · 10 −5 eV 2 at 90 % C.L. The atmospheric neutrino measurements [3] combined with the results of K2K [4] long baseline and CHOOZ [5] reactor measurements, constrain to 0.9 < sin 2 θ 23 < 1 at 90 % C.L.…”
