Probing Large Extra Dimensions with Neutrinos

  title={Probing Large Extra Dimensions with Neutrinos},
  author={G. R. Dvali and Alexei Yu. Smirnov},
  journal={Nuclear Physics},
We study implications of theories with sub-millimeter extra dimensions and Mf∼(1–10) TeV scale quantum gravity for neutrino physics. In these theories, the left-handed neutrinos as well as other standard model (SM) particles, are localized on a brane embedded in the bulk of large extra space. Mixing of neutrinos with (SM) singlet fermions propagating in the bulk is naturally suppressed by the volume factor Mf/MP∼3×10−16–3×10−15, where MP is the Planck mass. Properties of the neutrino… Expand

Remarks on models with singlet neutrino in large extra dimensions
Abstract Small Dirac masses for neutrinos are natural in models with singlet fermions in large extra dimensions with quantum gravity scale M ∗ ∼1−100 TeV. We study two modifications of the minimalExpand
Neutrinoless Double Beta Decay from Singlet Neutrinos in Extra Dimensions
We study the model-building conditions under which a sizable 0nbb-decay signal to the recently reported level of 0.4 eV is due to Kaluza-Klein singlet neutrinos in theories with large extraExpand
Neutrino masses and mixing in brane world theories
We present a comprehensive study of five-dimensional brane-world models for neutrino physics based on flat compactifications. Particular emphasis is put on the inclusion of bulk mass terms. We deriveExpand
Neutrinos in large extra dimensions and short-baseline νe appearance
We show that, in the presence of bulk masses, sterile neutrinos propagating in large extra dimensions (LED) can induce electron-neutrino appearance effects. This is in contrast to what happens in theExpand
Classical running of neutrino masses from six dimensions
We discuss a six dimensional mass generation for the neutrinos. Active neutrinos live on a three-brane and interact via a brane localized mass term with a bulk six-dimensional standard model singletExpand
Probing Large Extra Dimensions With IceCube
In models with Large Extra Dimensions the smallness of neutrino masses can be naturally explained by introducing gauge singlet fermions which propagate in the bulk. The Kaluza-Klein modes of theseExpand
Neutrinos confronting large extra dimensions
Abstract We study neutrino physics in a model with one large extra dimension. We assume the existence of two four-dimensional branes in the five-dimensional spacetime, one for the ordinary particlesExpand
Reactor searches for neutrino magnetic moment as a probe of extra dimensions

MSLED, neutrino oscillations and the cosmological constant
We explore the implications for neutrino masses and mixings within the minimal version of the supersymmetric large-extra-dimensions scenario (MSLED). This model was proposed in [10] to extract theExpand
Invisible decays of Higgs and other mesons in models with singlet neutrinos in large extra dimensions
Abstract In light of current atmospheric neutrino oscillation data, we revisit the invisible decay of the standard model Higgs boson and other pseudoscalar mesons which can be enhanced because ofExpand


Phenomenology, astrophysics and cosmology of theories with submillimeter dimensions and TeV scale quantum gravity
We recently proposed a solution to the hierarchy problem not relying on low-energy supersymmetry or technicolor. Instead, the problem is nullified by bringing quantum gravity down to the TeV scale.Expand
Cosmological nucleosynthesis and active-sterile neutrino oscillations with small mass differences: The nonresonant case
We study the nonresonant oscillations between left-handed electron neutrinos nu_e and nonthermalized sterile neutrinos nu_s in the early Universe plasma. The case when nu_s do not thermalize till 2Expand

Grand unification at intermediate mass scales through extra dimensions
Abstract One of the drawbacks of conventional grand unification scenarios has been that the unification scale is too high to permit direct exploration. In this paper, we show that the unificationExpand

It is shown how the next generation of solar neutrino experiments should be able to determine the resolution of the solar neutRino problem and how sterile neutrinos remain a viable dark matter candidate. Expand
