“…At this experiment, oscillations enter the averaged-out regime for ∆m 2 4 eV 2 . Recent competitive constraints on this parameter by the Daya Bay experiment [83] tend to dominate for smaller ∆m 2 values and are comparable to the bounds from BUGEY-3 [46] around ∆m 2 0.1 eV 2 . In the range ∆m 2 0.1-1 eV 2 the bound oscillates significantly between 3.0 · 10 −3 and 1.0 · 10 −2 : therefore, we quote the latter more conservative bound in the rightmost column of table 1.…”

Abstract:The simplest Standard Model extension to explain neutrino masses involves the addition of right-handed neutrinos. At some level, this extension will impact neutrino oscillation searches. In this work we explore the differences and similarities between the case in which these neutrinos are kinematically accessible (sterile neutrinos) or not (mixing matrix non-unitarity). We clarify apparent inconsistencies in the present literature when using different parametrizations to describe these effects and recast both limits in the popular neutrino non-standard interaction (NSI) formalism. We find that, in the limit in which sterile oscillations are averaged out at the near detector, their effects at the far detector coincide with non-unitarity at leading order, even in presence of a matter potential. We also summarize the present bounds existing in both limits and compare them with the expected sensitivities of near-future facilities taking the DUNE proposal as a benchmark. We conclude that non-unitarity effects are too constrained to impact present or near future neutrino oscillation facilities but that sterile neutrinos can play an important role at long baseline experiments. The role of the near detector is also discussed in detail.

“…As we are focused on the electron-sterile coupling it is thus only the ν e → ν e andν e →ν e experiments sensitive to sin 2 2θ ee ≈ 4|V eN | 2 that are relevant. For sub-eV sterile neutrino masses the Daya Bay [125], KamLAND [54] and upcoming JUNO [126] experiments can probe the mixing down to |V eN | 2 10 −3 . However it should be noted that if one wants to fit the solar and atmospheric mass splittings in a minimal (3+1) or (3+2) extension, solar data excludes the region 10 −9 eV < m N < 0.6 eV [47,55].…”

We make a comparative study of the neutrinoless double beta decay constraints on heavy sterile neutrinos versus other direct and indirect constraints from both lepton number conserving and violating processes, as a sensitive probe of the extent of lepton number violation and possible interference effects in the sterile sector. To this effect, we introduce a phenomenological parametrisation of the simplified one-generation seesaw model with one active and two sterile neutrino states in terms of experimentally measurable quantities, such as active-sterile neutrino mixing angles, CP phases, masses and mass splittings. This simple parametrisation enables us to analytically derive a spectrum of possible scenarios between the canonical seesaw with purely Majorana heavy neutrinos and inverse seesaw with pseudo-Dirac ones. We then go on to constrain the simplified parameters of this model from various experiments in energy, intensity and cosmic frontiers. We emphasise that the constraints from lepton number violating processes strongly depend on the mass splitting between the two sterile states and the relative CP phase between them. This is particularly relevant for the neutrinoless double beta decay constraint, which could now get significantly weaker for small mass splitting and opposite CP parities between the sterile states. It is important to keep this in mind while comparing the neutrinoless double beta decay constraint with the direct search limits in the electron flavour from high-energy colliders.

“…As shown in Figure 4, the estimated errors of sin 2 2θ 13 and |∆m 2 ee | will reach ∼ 3% by the year of 2020. In addition, Daya Bay experiment has been carring other important physics topics, including neutron captured on Hydrogen analysis [4], light sterile neutrino search [5,6] and reactor neutrino flux measurement [7].…”
