Abstract	After an introduction recalling the theoretical motivation for low energy (100 GeV to TeV scale) supersymmetry, this review describes the theory and experimental implications of the soft supersymmetry-breaking Lagrangian of the general minimal supersymmetric standard model (MSSM). Extensions to include neutrino masses and nonminimal theories are also discussed. Topics covered include models of supersymmetry breaking, phenomenological constraints from electroweak symmetry breaking, flavor/CP violation, collider searches, and cosmological constraints including dark matter and implications for baryogenesis and inflation.

$mSUGRA/CMSSM parameter space exclusion plots taken from \cite{Ellis:2003cw}, in which \protect$ A_{0}=0\protect $ and other parameters are as shown. The darkest ``V'' shaped thin strip corresponds to the region with \protect$ 0.094\leq \Omega h^{2}\leq 0.129\protect $, while a bigger strip with a similar shape corresponds to the region with \protect$ 0.1\leq \Omega h^{2}\leq 0.3\protect $. (There are other dark strips as well when examined carefully.) The triangular region in the lower right hand corner is excluded by \protect$ m_{\widetilde{\tau }_{1}}<m_{\widetilde{\chi }^{0}}\protect $, since DM cannot be charged and hence is a neutralino \protect$ \widetilde{\chi }^{0}\protect $). Other shadings and lines correspond to accelerator constraints. In the lower figure ( \protect$ \mu <0\protect $), most of the DM favored region below \protect$ m_{1/2}<400\protect $ GeV is ruled out by the \protect$ b\rightarrow s\gamma \protect $ constraint. In the upper figure, the medium shaded band encompassing the bulge region shows that the region favored by dark matter constraints is in concordance with the region favored by \protect$ g_{\mu }-2\protect $ measurements. The Higgs and chargino mass bounds are also as indicated: the parameter space left of these bounds is ruled out. Unless excluded by accelerator constraints, the region below the darkest {}``V'' region is not excluded, but is not cosmologically interesting due to the small relic abundance.$ $mSUGRA/CMSSM parameter space exclusion plots taken from \cite{Ellis:2003cw}, in which \protect$ A_{0}=0\protect $ and other parameters are as shown.
