We discuss gravitationally induced masses and mass splittings of Majorana, Zeldovich-Konopinski-Mahmoud, and Dirac neutrinos. Among other implications, these effects can provide a solution of the solar neutrino puzzle. In particular, we show how this may work in the 17 keV neutrino picture.

Neutrino Masses from Planck-Scale Lepton Number Breaking.
It is argued that, under plausible assumptions, a neutrino mass of O(0.1)  eV is naturally generated by the breaking of the lepton number at the Planck scale, possibly by gravitational effects, without the necessity of introducing new mass scales in the model.
Physical scales and neutrino masses in Grand Unified Theories
The determination of neutrino masses in Grand Unification is intimately related to the unification constraints on the symmetry breaking scale. We discuss some well-known but often overlooked problems
Light neutrino masses from gravitational condensation: the Schwinger–Dyson approach
In this work we demonstrate that non-zero neutrino masses can be generated from gravitational interactions. We solve the Schwinger-Dyson equations to find a non-trivial vacuum thereby determining the
Understanding neutrino masses and mixings
We discuss ways to understand large neutrino mixings using new symmetries of quarks and leptons beyond the standard model for the three allowed patterns of neutrino masses: normal, inverted hierarchy
Neutrinoless double beta decay and the solar neutrino problem
Abstract The MSW or vacuum oscillation solution of the solar neutrino problem can be reconciled with the possible existence of the ( ββ ) 0 ν decay with a half-life corresponding to an effective
Towards a grand unified picture for neutrino and quark mixings
The comparison of the CKM mixing angles with the leptonic mixings implied by the recent atmospheric and solar neutrino data exhibits an interesting complementarity. This pattern can be understood in
Origin of neutrino masses and mixings
Abstract A brief overview of the important theoretical issues in neutrino physics is presented and some of the current ideas for addressing them in the framework of the seesaw mechanism of neutrino
Theories of Neutrino Masses and Mixings
The history of weak-interaction physics has to a large extent been a history of our understanding of the properties of the elusive spin-half particles called neutrinos. Evidence for only left-handed
Renormalization of the neutrino mass operator
Abstract A small neutrino Majorana mass can arise in the Standard Model as an effective dimension 5 operator. We calculate the renormalization of this operator in the minimal Standard Model and in
Sterile Neutrinos and Leptogenesis of Matter and Dark Matter
Abstract Sterile neutrinos can naturally emerge as neutrinos from a shadow or mirror gauge sector. Among other interesting phenomenological and astrophysical implications, this picture suggests the
