Neutrino versus antineutrino oscillation parameters at DUNE and Hyper-Kamiokande experiments

“…Results for the inverted hierarchy are similar (up to ∆m 2 32 approximately changing sign). These are consistent with results from MINOS [46], NOνA [48], and atmospheric neutrino data [37]. 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.…”

“…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 .…”

“…MINOS, T2K and NOνA-Accelerator experiments sensitive to ν µ -disappearance for L/E values around 10 3 eV −2 provide the most stringent bounds on ∆m 2 32 and sin 2 θ 23 [39,[46][47][48]. 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.…”

Status of three-neutrino oscillation parameters, circa 2013

“…LBL Acc. + Solar + KL data Concerning LBL accelerator data, we include the observed energy spectra of events, in both appearance (muonto-electron flavor) and disappearance (muon-to-muon flavor) oscillation modes, as presented by the T2K [17][18][19] and MINOS [20][21][22][23] experiments. The theoretical spectra are calculated through a suitably modified version of the GLoBES software package [24,25].…”

“…The vast majority of experimental results on neutrino flavor oscillations converge towards a simple three-neutrino (3ν) framework, where the flavor states ν α = (ν e , ν µ , ν τ ) mix with the massive states ν i = (ν 1 , ν 3 , ν 3 ) via three mixing angles (θ 12 , θ 13 , θ 23 ) and a possible CP-violating phase δ [1]. The observed oscillation frequencies are governed by two independent differences between the squared masses m 2 )/2, where ∆m 2 > 0 and < 0 correspond to normal hierarchy (NH) and inverted hierarchy (IH), respectively [2].…”
