There exists now a very successful standard model of the fundamental
constituents of matter and the forces which act between
them. Nevertheless, many basic issues are yet to be explored. The
theoretical particle physics research at UCR is concerned with the
extension of our knowledge at this exciting frontier. Some current
topics on which we are working include possible extensions of the
standard model and their experimental signatures, the unification of
all or some of the fundamental forces, the origin of mass, the
possible violation of fundamental conservation laws, and the fermion
and gauge boson masses from the dynamics of four-fermi interaction
models. Phenomenological studies and model building for hadron-hadron
and electron-positron scattering at high energies are an important
component of this program. In particular, there is a close
collaboration with the experimental group in testing theoretical
predictions on production of weak vector bosons, heavy quarks, and
super-symmetric particles.
Another exciting area which is currently under rapid development
concerns the interplay between particle physics and
astrophysics. Using the methods of both these subjects, phenomena not
accessible using Earth-bound experiments can be studied. Presently, we
are concerned with understanding the properties of neutrinos using
this approach.
