Here is a little more information:
The Standard Model of elementary particle physics describes the interactions of
quarks and leptons
with so-called gauge bosons which mediate the strong, weak and
electromagnetic interactions. The name, the Standard Model, is an
enormous understatement, since this theory has been tested by thousands
of experiments at all different energies and is tremendously successful.
However, this theory contains nineteen arbitrary parameters which are
fit to data. The goal of any theory which goes Beyond the Standard
Model is to understand the origin of these nineteen parameters. Thirteen
of these parameters are connected to the nine quark and lepton masses
and the four weak mixing angles and three determine the strengths of
the three forces of Nature this theory describes. Grand Unification and
Supersymmetry are two ingredients in many theories which try to
bring order to these nineteen arbitrary parameters. In my research,
I have constructed theories which successfully predict many of these
observed parameters. In addition, these theories then make predictions
for new and as yet unobserved phenomena. One of the most spectacular
of these would be the decay of the most stable form of matter known --
protons -- at the heart of all atoms. Experiments
at SuperKamiokande in Japan are now searching for this rare decay of the
proton. Equally spectacular would be the observation of supersymmetric
partners to the Standard Model particles. Soon the Large Hadron Collider [LHC]
will begin taking data. Observation of these SUSY particles may be
just around the corner.
