A Low Scale for Quark-Lepton Unification
Lawrence J. Hall, Claudio Andrea Manzari, Clara Murgui
The measured fermion masses may be pointing to the scale of quark-lepton unification. Studying the renormalization-group evolution of the Standard Model Yukawa couplings, we find t…
The Very Nearly Right Theory of Flavor
Nima Arkani-Hamed, Carolina Figueiredo, Lawrence J. Hall +1
A striking empirical observation about the CKM matrix is that the angles of the unitarity triangle are very close to , simple fractions of that…
Generating the fermion mass hierarchy at the TeV scale
Nima Arkani-Hamed, Carolina Figueiredo, Lawrence J. Hall +1
We propose a class of theories to generate quark and lepton mass matrices where the scale of new physics is at the TeV scale, without inducing the large flavor and CP violating pro…
A Flavor of SO(10) Unification with a Spinor Higgs
Juanca Carrasco-Martinez, Lawrence J. Hall, Keisuke Harigaya +1
We investigate Higgs Parity Unification-a realization of grand unification based on the Higgs Parity mechanism in which the Standard Model (SM) Higgs resides in a spinor r…
Radiative Majorana Neutrino Masses in a Parity Solution to the Strong CP Problem
Lawrence J. Hall, Keisuke Harigaya, Yogev Shpilman
The strong CP problem can be solved in Parity symmetric theories with electroweak gauge group containing broken by the minimal Higgs content. Neutrino mass…
Discrete Symmetries and Neutrino Mass Perturbations for θ_{13}
L. J. Hall, G. G. Ross
The recent measurement of the third lepton mixing angle, θ_{13}, has shown that, although small compared to θ_{12} and θ_{23}, it is much larger than anticipated in schemes that ge…
The Weak Mixing Angle From TeV Scale Quark-Lepton Unification
Z. Chacko, Lawrence J. Hall, Maxim Perelstein
Unified theories based on an extended left-right symmetric group, , are constructed in five dimensions. The compactification scale is assumed to be only a loo…
Towards a theory of quark and lepton masses
Lawrence J. Hall
Has any progress been made on understanding and predicting the 13 parameters which describe the observed masses and mixing angles of the quarks and leptons? Arguments are given in…
