Supersymmetric SO(N) from a Planck-scale statistical theory
Several refinements are made in a theory which starts with a Planck-scale
statistical picture and ends with supersymmetry and a coupling of fundamental
fermions and bosons to SO(N) gauge fields. In particular, more satisfactory
treatments are given for (1) the transformation from the initial Euclidean form
of the path integral for fermionic fields to the usual Lorentzian form, (2) the
corresponding transformation for bosonic fields (which is much less
straightforward), (3) the transformation from an initial primitive
supersymmetry to the final standard form (containing, e.g., scalar sfermions
and their auxiliary fields), (4) the initial statistical picture, and (5) the
transformation to an action which is invariant under general coordinate
transformations.Comment: 12 pages, proceedings of Beyond the Standard Models 2010 (Capetown,

A statistical superfield and its observable consequences
A new kind of fundamental superfield is proposed, with an Ising-like
Euclidean action. Near the Planck energy it undergoes its first stage of
symmetry-breaking, and the ordered phase is assumed to support specific kinds
of topological defects. This picture leads to a low-energy Lagrangian which is
similar to that of standard physics, but there are interesting and observable
differences. For example, the cosmological constant vanishes, fermions have an
extra coupling to gravity, the gravitational interaction of W-bosons is
modified, and Higgs bosons have an unconventional equation of motion.Comment: 35 pages, LaTe
Dark Matter, Quantum Gravity, Vacuum Energy, and Lorentz Invariance
We discuss the problems of dark matter, quantum gravity, and vacuum energy
within the context of a theory for which Lorentz invariance is not postulated,
but instead emerges as a natural consequence in the physical regimes where it
has been tested.Comment: 5 pages; to be published in the proceedings of the Second Meeting on
