We present a comprehensive phenomenological analysis of a vast amount of data from
neutrino flavor oscillation and non-oscillation searches, performed within the standard …

Under a hypothesis of classically conformal theories, we investigate the minimal B–L
extended Standard Model, which naturally provides the seesaw mechanism for explaining …

The experimental rate of neutrinoless double beta decay can be saturated by the exchange
of virtual sterile neutrinos, that mix with the ordinary neutrinos and are heavier than 200 …

Taking into account the recent progress in the understanding of the lepton flavor effects in
leptogenesis, we investigate in detail the possibility that the CP-violation necessary for the …

The conclusions of the Physics Working Group of the International Scoping Study of a future
Neutrino Factory and super-beam facility (the ISS) are presented. The ISS was carried out by …

Assuming 3-ν mixing, massive Majorana neutrinos and neutrinoless double-beta ((ββ) 0ν-)
decay generated only by the (V− A) charged current weak interaction via the exchange of …

We review SO (10) grand unified theories (GUTs) in four and five dimensions (4D and 5D).
The renormalizable minimal SO (10) SUSY GUT is the central theme of this paper. It is very …

We propose that leptonic CP violation arises from a breaking of the μ-τ exchange symmetry
in the neutrino mass matrix which in turn is indicated by the near maximal atmospheric …

Current neutrino data are consistent with the so-called tribimaximal mixing scenario, which
predicts sin2θ12= 1/3, zero Ue3 and maximal θ23. This implies a special form of the …

It has been shown that tribimaximal mixing can be obtained by some particular breaking
pattern of the A 4 symmetry, wherein the extra A 4 triplet Higgs scalars pick up certain fixed …
