A Built-in Horizontal Symmetry of
C. S. Lam
In a renormalizable theory, all fermion mass matrices are linear combinations of three fundamental types, , and , whose superscripts i…
A Horizontal Symmetry for Leptons and Quarks
C. S. Lam
A generic valon potential invariant under U(1)\x SO(3) is used to determine whether the horizontal symmetry of leptons is , , or some other finite subgroups of SO(3). Val…
Horizontal Symmetry from the Bottom Up
C. S. Lam
A general method to derive horizontal symmetry from a mixing matrix is reviewed. The technique has been applied to deduce leptonic symmetry from the tri-bimaximal neutrino mixing m…
A Higgs Test of Horizontal Symmetry
C. S. Lam
Identical interactions found in the three families of quarks and leptons suggest the presence of a horizontal symmetry. We discuss how such a symmetry can be tested by measuring th…
Probing Extra Dimensions with Neutrino Oscillations
C. S. Lam
In the braneworld scenario, gravity and neutrino oscillation can both be used to detect the presence of an extra dimension. We argue that neutrino oscillation is particularly suita…
Neutrino Oscillations in Extra Dimensions
C. S. Lam
The characteristics and phenomenology of neutrino oscillation in extra dimensions are briefly reviewed
Time Ordering, Energy Ordering, and Factorization
C. S. Lam
Relations between integrals of time-ordered product of operators, and their representation in terms of energy-ordered products are studied. Both can be decomposed into irreducible…
From Multiloop Spinor Helicity Technique to String Reorganization
C. S. Lam
The success of the spinor helicity technique for tree processes is reviewed. To apply it to multiloop diagrams one is naturally led to the Schwinger proper-time representation, who…
