Beyond the
Standard Model
Our present understanding of the structure of matter at its most
microscopic level is in terms of the socalled standard model of strong,
weak and electromagnetic interactions. The model prescribes that
all matter is built out of some fermions (called quarks and leptons)
that interact with spin1 fields (gluons, W, Z, and photon) which are
manifestations of gauge symmetries.
In spite of the success that the model has had in accounting
for phenomena that can be probed at the energies available with current
accelerators, it is nevertheless considered
incomplete for a variety of reasons. The model has too many unexplained,
arbitrary parameters, such as the masses of the fermions,
which take on a perplexing variety of values. In fact,
mass generation appears to indicate that some new physics
must manifest itself at or below energies of order 1 TeV.
The model also does not include dark matter or
take gravity into account.
The particle theorists working on physics beyond the standard model
investigate various
aspects related to these considerations, some leading to direct experimental
consequences and others providing deeper insights into the underlying
theoretical and mathematical structures, with possible connections
to other areas of physics.
Subjects of particular interest include:
extra spatial dimensions (some studies)
supersymmetry (some studies, and a
review)
electroweak symmentry breaking (some studies)
...
