We present a 5D axion-neutrino model that explains the Standard Model fermion mass hierarchy and flavor structure, while simultaneously generating a high-quality axion. The axion and righthanded neutrinos transform under a 5D Peccei-Quinn gauge symmetry, and have highly suppressed profiles on the UV brane where the symmetry is explicitly broken. This setup allows neutrinos to be either Dirac, or Majorana with hierarchically small sterile neutrino masses. The axion decay constant originates from… Expand

Massive neutrinos and invisible axion minimally connected
We survey a few minimal scalar extensions of the standard electroweak model that provide a simple setup for massive neutrinos in connection with an invisible axion. The presence of a chiral $U(1)$Expand
Warped seesaw mechanism is physically inverted
Warped extra dimensions can address both the Planck-weak and flavor hierarchies of the Standard Model (SM). In this paper we discuss the SM neutrino mass generation in a scenario in which a SMExpand
Common origin for neutrino anarchy and charged hierarchies.
The generation of exponential flavor hierarchies from extra-dimensional wave function overlaps is reexamined. We find, surprisingly, that the coexistence of anarchic fermion mass matrices with suchExpand

Fermion Masses, Mixings and Proton Decay in a Randall-Sundrum Model
We consider a Randall–Sundrum model in which the Standard Model fermions and gauge bosons correspond to bulk fields. We show how the observed charged fermion masses and CKM mixings can be explained,Expand

It is argued that the Peccei—QuinnU(1)PQ symmetry, needed to solve the strong CP-problem, and the localB−L symmetry of weak interactions may be broken at the same large mass scale leading to massiveExpand

Physical arguments involving the solar neutrino problem are given which connect the scale of U(1)PQ breakdown with that of the spontaneous breakdown of lepton number. In the simplest model, theExpand
Lepton masses and flavor violation in the Randall-Sundrum model
Lepton masses and mixing angles via localization of 5-dimensional fields in the bulk are revisited in the context of Randall-Sundrum models. The Higgs is assumed to be localized on the IR brane.Expand
A holographic perspective on the axion quality problem
The axion provides a compelling solution to the strong CP problem as well as a candidate for the dark matter of the universe. However, the axion solution relies on the spontaneous breaking of aExpand

We show how the seesaw mechanism for neutrino masses can be realized within a five-dimensional (5D) warped geometry framework. Intermediate scale standard model (SM) singlet neutrino masses, neededExpand
