  Title New neutrino mass sum rule from the inverse seesaw mechanism Type Journal Article
  Year 2012 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 86 Issue 5 Pages 056001 - 9pp  
  Keywords  
  Abstract A class of discrete flavor-symmetry-based models predicts constrained neutrino mass matrix schemes that lead to specific neutrino mass sum rules. One of these implies a lower bound on the effective neutrinoless double beta mass parameter, even for normal hierarchy neutrinos. Here we propose a new model based on the S-4 flavor symmetry that leads to the new neutrino mass sum rule and discuss how to generate a nonzero value for the reactor angle theta(13) indicated by recent experiments, and the resulting correlation with the solar angle theta(12).

  Title Predictive discrete dark matter model and neutrino oscillations Type Journal Article
  Year 2012 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 86 Issue 7 Pages 073008 - 5pp  
  Keywords  
  Abstract Dark matter stability can be achieved through a partial breaking of a flavor symmetry. In this framework we propose a type-II seesaw model where left-handed matter transforms nontrivially under the flavor group Delta(54), providing correlations between neutrino oscillation parameters, consistent with the recent Daya-Bay and RENO reactor angle measurements, as well as lower bounds for neutrinoless double beta decay. The dark matter phenomenology is provided by a Higgs-portal.

  Title Bilarge neutrino mixing and Abelian flavor symmetry Type Journal Article
  Year 2013 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 87 Issue 5 Pages 053013 - 13pp  
  Keywords  
  Abstract We explore two bilarge neutrino mixing Anzatze within the context of Abelian flavor symmetry theories: (BL1) sin theta(12) similar to lambda, sin theta(13) similar to lambda, sin theta(23) similar to lambda, and (BL2) sin theta(12) similar to lambda, sin theta(13) similar to lambda, sin theta(23) similar to 1 – lambda. The first pattern is proposed by two of us and is favored if the atmospheric mixing angle theta(23) lies in the first octant, while the second one is preferred for the second octant of theta(23). In order to reproduce the second texture, we find that the flavor symmetry should be U(1) x Z(m), while for the first pattern the flavor symmetry should be extended to U(1) x Z(m) x Z(n) with m and n of different parity. Explicit models for both mixing patterns are constructed based on the flavor symmetries U(1) x Z(3) x Z(4) and U(1) x Z(2). The models are extended to the quark sector within the framework of SU(5) grand unified theory in order to give a successful description of quark and lepton masses and mixing simultaneously. Phenomenological implications are discussed.

  Title Neutrino mixing with revamped A(4) flavor symmetry Type Journal Article
  Year 2013 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 88 Issue 1 Pages 016003 - 7pp  
  Keywords  
  Abstract We suggest a minimal extension of the simplest A(4) flavor model that can induce a nonzero theta(13) value, as required by recent neutrino oscillation data from reactors and accelerators. The predicted correlation between the atmospheric mixing angle theta(23) and the magnitude of theta(13) leads to an allowed region substantially smaller than indicated by neutrino-oscillation global fits. Moreover, the scheme correlates CP violation in neutrino oscillations with the octant of the atmospheric mixing parameter theta(23) in such a way that, for example, maximal mixing necessarily violates CP. We briefly comment on other phenomenological features of the model.

  Title Quark-lepton mass relation and CKM mixing in an A(4) extension of the minimal supersymmetric standard model Type Journal Article
  Year 2013 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 88 Issue 3 Pages 036001 - 8pp  
  Keywords  
  Abstract An interesting mass relation between down-type quarks and charged leptons has been recently predicted within a supersymmetric SU(3)(c) circle times SU(2)(L) circle times U(1)(Y) model based on the A(4) flavor symmetry. Here we propose a simple extension which provides an adequate full description of the quark sector. By adding a pair of vectorlike up quarks, we show how the CKM entries V-ub, V-cb, V-td and V-ts arise from deviations of the unitarity. We perform an analysis including the most relevant observables in the quark sector, such as oscillations and rare decays of kaons, B-d and B-s mesons. In the lepton sector, the model predicts an inverted hierarchy for the neutrino masses, leading to a potentially observable rate of neutrinoless double beta decay.

  Title Dirac neutrinos from flavor symmetry Type Journal Article
  Year 2014 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 89 Issue 3 Pages 033001 - 5pp  
  Keywords  
  Abstract We present a model where Majorana neutrino mass terms are forbidden by the flavor symmetry group Delta(27). Neutrinos are Dirac fermions and their masses arise in the same way as those of the charged fermions, due to very small Yukawa couplings. The model fits current neutrino oscillation data and correlates the octant of the atmospheric angle theta(23) with the magnitude of the lightest neutrino mass, with maximal mixing excluded for any neutrino mass hierarchy.

  Title Radiative neutrino mass in 3-3-1 scheme Type Journal Article
  Year 2014 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 90 Issue 1 Pages 013005 - 5pp  
  Keywords  
  Abstract We propose a new radiative mechanism for neutrino mass generation based on the SU(3)(c) circle times SU(3)(L) circle times U(1)(X) electroweak gauge group. Lepton number is a symmetry of the Yukawa sector which is spontaneously broken in the gauge sector. As a result light Majorana masses arise from neutral gauge boson exchanges at the one-loop level. In addition to the isosinglet neutrinos that may be produced at the LHC through the extended gauge boson portals, the model contains new quarks which can also lie at the TeV scale, and which can provide a plethora of accessible collider phenomena.

  Title Inflation and majoron dark matter in the neutrino seesaw mechanism Type Journal Article
  Year 2014 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 90 Issue 5 Pages 055023 - 6pp  
  Keywords  
  Abstract We propose that inflation and dark matter have a common origin, connected to the neutrino mass generation scheme. As a model we consider spontaneous breaking of global lepton number within the seesaw mechanism. We show that it provides an acceptable inflationary scenario consistent with the recent cosmic microwave background B-mode observation by the BICEP2 experiment. The scheme may also account for the baryon asymmetry of the Universe through leptogenesis for reasonable parameter choices.

  Title LHC diphoton resonance from gauge symmetry Type Journal Article
  Year 2016 Publication (up) Physical Review D Abbreviated Journal Phys. Rev. D  
  Volume 93 Issue 11 Pages 115008 - 8pp  
  Keywords  
  Abstract Motivated by what is possibly the first sign of new physics seen at the LHC, the diphoton excess at 750 GeV in ATLAS and CMS, we present a model that provides naturally the necessary ingredients to explain the resonance. The simplest phenomenological explanation for the diphoton excess requires a new scalar state, X(750), as well as additional vectorlike (VL) fermions introduced in an ad-hoc way in order to enhance its decays into a pair of photons and/or increase its production cross section. We show that the necessary VL quarks and their couplings can emerge naturally from a complete framework based on the SU(3)(L) circle times U(1)(X) gauge symmetry.

  Title Neutrino phenomenology and stable dark matter with A(4) Type Journal Article
  Year 2011 Publication (up) Physics Letters B Abbreviated Journal Phys. Lett. B  
  Volume 697 Issue 4 Pages 339-342  
  Keywords Flavor symmetries; Dark matter; Neutrino masses; Lepton mixing; Discrete symmetries; Neutrino less double beta decay  
  Abstract We present a model based on the A(4) non-Abelian discrete symmetry leading to a predictive five-parameter neutrino mass matrix and providing a stable dark matter candidate. We found an interesting correlation among the atmospheric and the reactor angles which predicts theta(23) similar to pi/4for very small reactor angle and deviation from maximal atmospheric mixing for large theta(13). Only normal neutrino mass spectrum is possible and the effective mass entering the neutrinoless double beta decay rate is constrained to be vertical bar m(ee)vertical bar > 4 x 10(-4) eV.
