Current neutrino data are consistent with the soâ€“called tribimaximal mixing scenario, which predicts sin Î¸12 = 1/3, zero Ue3 and maximal Î¸23. This implies a special form of the neutrino mass matrix.â€¦ (More)

We analyze the impact of a measurement, or of an improved bound, on Î¸13 for the determination of the effective neutrino mass in neutrino-less double beta decay and cosmology. In particular, weâ€¦ (More)

After a brief overview of the present knowledge of neutrino masses and mixing, we summarize what can be learned about physics beyond the standard model from the various proposed neutrino experiments.â€¦ (More)

It has recently been speculated that the solar neutrino mixing angle is connected to the golden ratio Ï†. Two such proposals have been made, cot Î¸12 = Ï† and cos Î¸12 = Ï†/2. We compare these AnsÃ¤tze andâ€¦ (More)

We consider the seeâ€“saw mechanism for hierarchical Dirac and Majorana neutrino mass matrices mD and MR, including the CP violating phases. Simple arguments about the structure of the neutrino massâ€¦ (More)

We study the range of the elements of the neutrino mass matrix mÎ½ in the charged lepton basis. Neutrino-less double beta decay is sensitive to the ee element (the effective mass) of mÎ½ . We thenâ€¦ (More)

Assuming 3-Î½ mixing, neutrino oscillation explanation of the solar and atmospheric neutrino data and of the first KamLAND results, massive Majorana neutrinos and neutrinoless double-beta ((Î²Î²) 0Î½-)â€¦ (More)

We propose a new parametrization for the quark and lepton mixing matrices: the two 12-mixing angles (the Cabibbo angle and the angle responsible for solar neutrino oscillations) are at zeroth orderâ€¦ (More)

We perform a statistical analysis with the prospective results of future experiments on neutrino-less double beta decay, direct searches for neutrino mass (KATRIN) and cosmological observations.â€¦ (More)

Starting from a degenerate scheme with mass m0 a complete analysis of the allowed range of the effective electron neutrino Majorana mass ã€ˆmã€‰ is performed. Special attention is paid to effects ofâ€¦ (More)
