The Family Group in Grand Unified Theories
P. Ramond
We review the known ways of incorporating and breaking symmetries in a renormalizable way. We summarize the various grand unified theories based on , and as fa…
Neutrinos: A Glimpse Beyond the Standard Model
P. Ramond
After a review of the early history of neutrinos and their detection, we analyze the different types of models that extend the standard model to massive neutrinos. We emphasize the…
The Weyl Character Formula, the half-spin representations, and equal rank subgroups
B. Gross, B. Kostant, P. Ramond +1
Let B be a reductive Lie subalgebra of a semi-simple Lie algebra of the same rank both over the complex numbers. To each finite dimensional irreducible representation of F we…
M(ysterious) Patterns in SO(9)
T. Pengpan, P. Ramond
The light-cone little group, SO(9), classifies the massless degrees of freedom of eleven-dimensional supergravity, with a triplet of representations. We observe that this triplet g…
A Model for Fermion Mass Hierarchies and Mixings
P. Ramond
We present a model which contains three Abelian symmetries beyond the standard model. One is anomalous {\it \` a la} Green-Schwarz, and family-independent; the other two are family…
The Case for a Standard Model with Anomalous U(1)
P. Ramond
A gauged phase symmetry with its anomalies cancelled by a Green-Schwarz mechanism, broken at a large scale by an induced Fayet-Iliopoulos term, is a generic feature of a large clas…
Pseudo-anomalous U(1) symmetry in the strong coupling limit of the heterotic string
P. Binetruy, C. Deffayet, E. Dudas +1
We discuss, in the context of the strongly coupled E_8 \times E_8 heterotic string proposed by Horava and Witten, the appearance of anomalous U(1)_X symmetries of a nonperturbative…
Family Symmetry and Neutrino Mixing
John K. Elwood, Nikolaos Irges, Pierre Ramond
The observed quark hierarchies suggest a simple family symmetry. Generalized to leptons through grand-unified quantum numbers, it produces a neutrino mixing matrix with order-one ν…
Predictions from an Anomalous U(1) Model of Yukawa Hierarchies
Nikolaos Irges, Stephane Lavignac, Pierre Ramond
We present a supersymmetric standard model with three gauged Abelian symmetries, of a type commonly found in superstrings. One is anomalous, the other two are family symmetri…
