Coset Space Dimensional Reduction and Wilson Flux Breaking of Ten-Dimensional N=1, E(8) Gauge Theory
We consider a N=1 supersymmetric E(8) gauge theory, defined in ten dimensions
and we determine all four-dimensional gauge theories resulting from the
generalized dimensional reduction a la Forgacs-Manton over coset spaces,
followed by a subsequent application of the Wilson flux spontaneous symmetry
breaking mechanism. Our investigation is constrained only by the requirements
that (i) the dimensional reduction leads to the potentially phenomenologically
interesting, anomaly free, four-dimensional E(6), SO(10) and SU(5) GUTs and
(ii) the Wilson flux mechanism makes use only of the freely acting discrete
symmetries of all possible six-dimensional coset spaces.Comment: 45 pages, 2 figures, 10 tables, uses xy.sty, longtable.sty,

Ultrahigh-Energy Neutrino Interactions
Cross sections for the interactions of ultrahigh-energy neutrinos with
nucleons are evaluated in light of new information about nucleon structure
functions. For --eV neutrinos, the cross section is about 2.4 times
previous estimates. We also review the cross sections for neutrino interactions
with atomic electrons. Some consequences for interaction rates in the Earth and
for event rates from generic astrophysical sources in large-scale detectors are
noted.Comment: 51 pages, LaTeX, uses elsart.sty and BoxedEPS for 23 uufiled
