The Neutrino Mass Direct Measurements
One of the most important tasks in neutrino physics is to determine the neutrino mass scale to distinguish between hierarchical and degenerate neutrino mass models and to clarify the role of neutrinos as dark matter particles in the universe. The current tritium β decay experiments at Mainz and Troitsk are reaching their sensitivity limit. The different options for a next generation direct neut...
متن کاملImplications of Weak-Interaction Space Deformation for Neutrino Mass Measurements
The negative values for the squares of both electron and muon neutrino masses obtained in recent experiments are explained as a possible consequence of a change in metric within the weak-interaction volume in the energy-momentum representation. Using a model inspired by a combination of the general theory of relativity and the theory of deformation for continuous media, it is shown that the neg...
متن کاملDetermining Neutrino Mass Hierarchy by Precision Measurements in Electron and Muon Neutrino Disappearance Experiments
Recently a new method for determining the neutrino mass hierarchy by comparing the effective values of the atmospheric ∆m measured in the electron neutrino disappearance channel, ∆m(ee), with the one measured in the muon neutrino disappearance channel, ∆m(μμ), was proposed. If ∆m(ee) is larger (smaller) than ∆m(μμ) the hierarchy is of the normal (inverted) type. We re-examine this proposition i...
متن کاملPhysics of Neutrino Mass
For a long time, it was believed that neutrinos are massless, spin half particles, making them drastically different from their other standard model spin half cousins such as the charged leptons (e, μ, τ) and the quarks (u, d, s, c, t, b), which are known to have mass. In fact the masslessness of the neutrino was considered so sacred in the 1950s and 1960s that the fundamental law of weak inter...
متن کاملSolar Neutrino Measurements
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...
