A Relation between theta-13 and the Leptonic Dirac CP Phase in SO(10) Lopsided Models
Stephen M. Barr, Almas Khan
It is shown that in SO(10) models where the large solar and atmospheric neutrino angles come from the charged-lepton mass being "lopsided", there is a characteristic relation betwe…
A Realistic Radiative Fermion Mass Hierarchy in Non-supersymmetric SO(10)
S. M. Barr, Almas Khan
A non-supersymmetric grand unified theory can exhibit a "radiative fermion mass hierarchy", in which the heavier quarks and leptons get mass at tree level and the lighter ones get…
Anthropic tuning of the weak scale and of m_u/m_d in two-Higgs-doublet models
S. M. Barr, Almas Khan
It is shown that in a model in which up-type and down-type fermions acquire mass from different Higgs doublets, the anthropic tuning of the Higgs mass parameters can explain the fa…
Extra bosons and low-energy tests of unification
S. M. Barr, Almas Khan
If there is an extra U(1) gauge symmetry broken at low energies, then it may be possible from the charges of the known quarks and leptons under this U(1) to make inferences about h…
