“…While analyzing simulated data from DUNE or Hyper-K, we will not include any prior information on ∆m 2 32 and sin 2 θ 23 since these are expected to be better constrained by DUNE and Hyper-K independently. T2K and NOνA are also sensitive to the value of sin 2 θ 13 [47,48]. The T2K collaboration presented results on neutrino and antineutrino oscillation parameters separately, resulting in a bound on sin 2 θ 13 between 0.02 and 0.065 at 68.3% confidence level [47].…”

“…Neutrino oscillation parameters are mostly constrained by solar neutrino experiments [40][41][42][43][44][45], the SuperKamiokande atmospheric neutrino data [37], and accelerator data from MINOS [46], T2K [47], and the NuMI Off-Axis ν e Appearance Experiment (NOνA) [48]. These imply the existence of two hierarchical mass-squared differences ∆m 2 21 and ∆m 2 32 and three nonzero mixing angles θ 13 , θ 12 , θ 23 .…”

The results recently published by T2K are ∆m 2 32 = (2.54 ± 0.08) × 10 −3 eV 2 and sin 2 θ 23 = 0.55 +0.05 −0.09 [47], both for a normal mass-hierarchy.…”

Testing, in a non-trivial, model-independent way, the hypothesis that the three-massive-neutrinos paradigm properly describes nature is among the main goals of the current and the next generation of neutrino oscillation experiments. In the coming decade, the DUNE and Hyper-Kamiokande experiments will be able to study the oscillation of both neutrinos and antineutrinos with unprecedented precision. We explore the ability of these experiments, and combinations of them, to determine whether the parameters that govern these oscillations are the same for neutrinos and antineutrinos, as prescribed by the CPT-theorem. We find that both DUNE and Hyper-Kamiokande will be sensitive to unexplored levels of leptonic CPT-violation. Assuming the parameters for neutrino and antineutrino oscillations are unrelated, we discuss the ability of these experiments to determine the neutrino and antineutrino mass-hierarchies, atmospheric-mixing octants, and CP-odd phases, three key milestones of the experimental neutrino physics program. Additionally, if the CPT-theorem is violated in nature in a way that is consistent with all present neutrino and antineutrino oscillation data, we find that DUNE and Hyper-Kamiokande have the potential to ultimately establish leptonic CPT-invariance violation.

“…The unknown oscillation parameters are: (i) the neutrino mass hierarchy i.e whether m 3 > m 2 > m 1 leading to normal hierarchy (NH) or if m 3 < m 2 ≈ m 1 resulting in inverted hierarchy (IH); (ii) the octant of θ 23 -if θ 23 < 45 • it is said to be in the lower octant (LO) and if θ 23 > 45 • it is in the higher octant (HO); (iii) the CP phase δ CP . There are some indications of these quantities from the recent results of the ongoing experiments T2K [3] and NOνA [4,5]. However no clear conclusions have been reached yet.…”

Abstract:We study the consequences of invisible decay of neutrinos in the context of the DUNE experiment. We assume that the third mass eigenstate is unstable and decays to a light sterile neutrino and a scalar or a pseudo-scalar. We consider DUNE running in 5 years neutrino and 5 years antineutrino mode and a detector volume of 40 kt. We obtain the expected sensitivity on the rest-frame life-time τ 3 normalized to the mass m 3 as τ 3 /m 3 > 4.50 × 10 −11 s/eV at 90% C.L. for a normal hierarchical mass spectrum. We also find that DUNE can discover neutrino decay for τ 3 /m 3 > 4.27 × 10 −11 s/eV at 90% C.L. In addition, for an unstable ν 3 with an illustrative value of τ 3 /m 3 = 1.2 × 10 −11 s/eV, the no decay case could get disfavoured at the 3σ C.L. At 90% C.L. the expected precision range for this true value is obtained as 1.71 × 10 −11 > τ 3 /m 3 > 9.29 × 10 −12 in units of s/eV. We also study the correlation between a non-zero τ 3 /m 3 and standard oscillation parameters and find an interesting correlation in the appearance and disappearance channels with the mixing angle θ 23 . This alters the octant sensitivity of DUNE, favorably (unfavorably) for true θ 23 in the lower (higher) octant. The effect of a decaying neutrino does not alter the hierarchy or CP violation discovery sensitivity of DUNE in a discernible way.
