Chiral Fermions and AdS/CFT Duality for a Nonabelian Orbifold
We present what we believe is the minimal three-family model
compactified on a nonabelian orbifold . Nontrivial
irreps of the discrete nonabelian group are identified with the
of symmetry to break all supersymmetries, and the scalar
content of the model is sufficient to break the gauge symmetry to the standard
model. According to the conformality hypothesis the progenitor theory becomes conformally invariant at an infra-red fixed point of
the renormalization group.Comment: 11 pages latex and one JPG figur
Using Newton's Law for Dark Energy
A model is introduced in which Newton's law is modified between matter and
dark energy corpuscles (DECs). The model predicts that the DEC component is
presently decelerating in its expansion at 14% of the magnitude of the matter
expansion acceleration. In the future, expansion of the DEC universe will
continue to decelerate.Comment: 4 pages, no figure
Seeking Gauge Bileptons in Linear Colliders
A promising direction to find physics beyond the standard model is to look
for violation of conservation. In particular the process with the exchange of a gauge bilepton has a striking
signal without background and is predicted in the most economical model to have
a cross-section an order of magnitude higher than previous estimates.Comment: 4 pages LaTeX and 5 postscript figure
Anomaly Cancellation and Conformality in Quiver Gauge Theories
Abelian quiver gauge theories provide nonsupersymmetric candidates for the
conformality approach to physics beyond the standard model. Written as , gauge theories, however, they have mixed and
triangle anomalies. It is shown how to construct explicitly
a compensatory term which restores gauge invariance of
under . It can
lead to a negative contribution to the U(1) -function and hence to
one-loop conformality at high energy for all dimensionless couplings.Comment: 15 pages. minor clarification
Identification of All Dark Matter as Black Holes
For the universe I use dimensionless entropy for which the
most convenient unit is the googol () and identify all dark matter as
black holes whereupon the present entropy is about a thousand googols. While
the energy of the universe has been established to be about 0.04 baryons, 0.24
dark matter and 0.72 dark energy, the cosmological entropy is almost entirely,
about , from black holes and only from everything
else. This identification of all dark matter as black holes is natural in
statistical mechanics.Comment: Discussion update
Lepton Number Conservation, Long-lived Quarks and Superweak Bileptonic Decays
In the upcoming LHC Run 2, at TeV, it is suggested to seek
unusually charged ( and ) quarks with mass TeV
which carry lepton number ( and respectively) and decay
superweakly to a bilepton with mass TeV and a usual quark.
These long-lived decays will have displaced decay vertices and produce a
striking final state in which contains two separated jets together with
two pairs of correlated like-sign charged leptons. Such a process was
inaccessible energetically in LHC Run 1 with TeV. The simplest
theoretical explanation is the 331-model which has new physics necessarily
below TeV and which explains the existence of three families by anomaly
cancellation.Comment: 7 pages LaTe
