We study bulk fermion fields in the localized gravity model with non-factorizable metric recently proposed by Randall and Sundrum, and Gogberashvili. In addition to a tower of weak-scale Kaluza-Klein states we find a zero mode for any value of the fundamental fermion mass. If the fermion mass is larger than half the curvature of the compact dimension, the zero mode can be localized on the ``hidden'' 3-brane in the Randall-Sundrum model. Identifying this mode with a right-handed neutrino provides a new way for obtaining small Dirac neutrino masses without invoking a see-saw mechanism. Cancellation of the parity anomaly requires introducing an even number of bulk fermions. This naturally leads to a strong hierarchy of neutrino masses and generically large mixing angles.

First Search for Kaluza-Klein Gravitons and Radion Using Planck Data
First Planck search for radion and KK-graviton bispectra finds no significant non-Gaussianity (max 1.8σ at m_KK ≈ 1.6H), while a warped 5D model can yield f_NL ~ 1–50.

Partial Compositeness: from Anarchy to Symmetry
A two-stage renormalization group flow, anarchic at high energies and flavor-symmetric at low energies, dynamically realizes Minimal Flavor Violation in composite Higgs models at a 5-10 TeV scale.

Gauged Flavour for Asymmetric Dark Matter
A gauged SO(3) flavour symmetry spontaneously broken at multiple scales links SM flavour hierarchies to asymmetric dark matter via leptogenesis and sphaleron redistribution, with DM as bound states of a confining SU(3).

Inequalities for Standard Model Yukawa Couplings
The paper proves rigorous, basis-independent inequalities on combinations of Standard Model Yukawa matrix entries that follow from the observed hierarchical fermion masses and CKM angles.

A geometric origin for the radiative neutrino portal to secluded dark matter
A brane-separated fifth dimension gives a geometric origin for the vanishing tree-level Higgs-hidden-scalar portal, leaving seesaw neutrinos to generate a small radiative portal that makes secluded dark matter viable ...

The Future of Lepton Flavor
Upcoming neutrino experiments are projected to substantially reduce the number of viable leptonic flavor models in five popular classes by measuring mass ordering, theta_23 octant, delta_CP, and absolute mass scale.

Fermionic Kaluza-Klein mode mixing in braneworlds
Perturbations induce KK mode mixing resolved by SVD of the Dirac mass matrix, with parity-odd operators preserving Z2 symmetry and parity-even operators breaking it to polarize wavefunctions toward the brane.
