Prospects for mass scale and inverted hierarchy in non oscillations experiments

چکیده

After the recent evidence of neutrino oscillations which imply the existence of neutrino masses and mixing, one of the most compelling questions in neutrino physics concerns the determination of the absolute values of neutrino masses. Various experimental strategies are and will be employed to answer this question. Here, I will review the non-oscillation techniques for neutrino mass determination with specific emphasis on direct neutrino mass searches and neutrinoless double beta decay.

Atmospheric Neutrino Oscillations, θ13 and Neutrino Mass Hierarchy

We derive predictions for the Nadir angle (θn) dependence of the ratio Nμ/Ne of the rates of the μ−like and e−like multi-GeV events measured in water-Čerenkov detectors in the case of 3-neutrino oscillations of the atmospheric νe (ν̄e) and νμ (ν̄μ), driven by one neutrino mass squared difference, |∆m31| ∼ (2.5− 3.0)× 10−3 eV2 ≫ ∆m21. This ratio is particularly sensitive to the Earth matter effect...

Neutrino mass matrix: inverted hierarchy and CP violation

We reconstruct the neutrino mass matrix in flavor basis, in the case of inverted mass hierarchy (ordering), using all available experimental data on neutrino masses and oscillations. We analyze the dependence of the matrix elements mαβ on the CP violating Dirac, δ, and Majorana, ρ and σ, phases, for different values of the absolute mass scale. We find that the present data admit various structu...

The Lma Msw Solution of the Solar Neutrino Problem, Inverted Neutrino Mass Hierarchy and Reactor Neutrino Experiments

In the context of three-neutrino oscillations, we study the possibility of using antineutrinos from nuclear reactors to explore the 10−4 eV2 < ∆m⊙ ∼< 8 × 10 −4 eV2 region of the LMA MSW solution of the solar neutrino problem. The KamLAND experiment is not expected to determine ∆m⊙ if the latter happens to lie in the indicated region. By analysing both the total event rate suppression and the en...

Identifying the neutrino mass spectrum from the neutrino burst from a supernova

The current data on solar and atmospheric neutrinos admit more than one solutions in terms of the oscillations between three neutrino species. We examine the consequences of these different masses-andmixing schemes for the observable spectra of neutrinos from the burst of a Type II supernova. We point out the distinguishing features of these schemes, and discuss the prospects of identifying the...

We give predictions for the up-down asymmetry in the Nadir angle dependence of the ratio Nμ/Ne of the rates of the μ−like and e−like multi-GeV events measured in water-Čerenkov detectors (Super-Kamiokande, etc.) in the case of 3-neutrino oscillations of the atmospheric νe (ν̄e) and νμ (ν̄μ), driven by one neutrino mass squared difference, |∆matm | ≡ |∆m 2 31| ∼ (2.0 − 3.0) × 10 −3 eV2 ≫ ∆m21 ≡ ∆m...
