Holographic Scattering Amplitudes
C. S. Lam
Inspired by ancient astronomy, we propose a holographic description of perturbative scattering amplitudes, as integrals over a `celestial sphere'. Since Lorentz invariance, local i…
Horizontal Symmetries and
C. S. Lam
Using group theory of mixing to examine all finite subgroups of SU(3) with an order less than 512, we found recently that only the group can give rise to a correct reactor…
Leptonic Mixing and Group Structure Constants
C. S. Lam
Hernandez and Smirnov discovered an interesting formula to parametrize each column of a neutrino mixing matrix by six integers related to the residual symmetry. We point out that t…
Finite Symmetry of Leptonic Mass Matrices
C. S. Lam
We search for possible symmetries present in the leptonic mixing data from SU(3) subgroups of order up to 511. Theoretical results based on symmetry are compared with global fits o…
Horizontal Symmetry: Bottom Up and Top Down
C. S. Lam
A group-theoretical connection between horizontal symmetry $\G$ and fermion mixing is established, and applied to neutrino mixing. The group-theoretical approach is consistent with…
Group Theory and Dynamics of Neutrino Mixing
C. S. Lam
There is a direct group-theoretical connection between neutrino mixing and horizontal symmetry that can be established without any dynamical input. Such a connection is reviewed an…
