For each model line, one may add on R-parity-violating decays in various ways. Sample model points for each line are chosen only for comparison purposes. The model lines can be extended at will according to the purposes of the investigator.

A note on indirect constraints: In many cases, parts of these model lines might be claimed to be "excluded" based on calculations of dark matter relic abundance, b -> s gamma, or the Higgs mass. However, these constraints only apply with quite strong assumptions regarding the detailed nature of the models, including assumptions which are impossible to test at colliders. Dark matter constraints are easily evaded by cosmological models with late inflation or a small amount of R-parity violation. b -> s gamma constraints are subject to significant uncertainty, and are again easily evaded by introducing small flavor-mixing A-terms which again would have no significant effect on the collider signals. Such flavor-mixing is expected in generic supergravity, and is not included in benchmark parameter sets only for simplicity. There is still a significant uncertainty in calculation of the lightest Higgs mass, and it can be changed by slightly increasing m_top or by enlarging the Higgs sector in ways which may or may not have an effect on collider signals. These model lines should therefore be viewed as benchmarks of signatures, rather than as guesses at exact model parameters which would necessarily depend heavily on assumptions.

Model Line A: mSUGRA with gaugino mass dominance. This model line features relatively light scalars, with very tau-rich neutralino and chargino decays. Left-handed sleptons have several different decay modes with comparable branching fractions. It is motivated by models in which SUSY breaking is dominated by gaugino masses near the Planck scale, thus solving the SUSY flavor problem. (Please note that Model Line A has been tweaked very slightly as of July 23, 2001.)

Model Line B: Non-unified gaugino masses. In this model line, the bino mass parameter M_1 is larger than in the usual mSUGRA models by a factor of 1.6. A bino-like neutralino is still the LSP. However, the mass difference between the lightest chargino and the lightest two neutralinos and the sleptons is dramatically reduced compared to the typical mSUGRA case. Neutralino, chargino and slepton decays will feature less-energetic jets and leptons as a consequence.

Model Line C: mSUGRA with heavy scalars. This model line features relatively heavy scalars. Chargino and neutralino decays therefore go almost 100% through W and Z.

Model Line D: GMSB with stau NLSP. The NLSP is a stau, with allowed three body decays of right-handed selectrons and smuons into it. The stau -> tau Goldstino decay can be chosen prompt, delayed, or quasi-stable.

Model Line E: GMSB with neutralino NLSP. The NLSP is the lightest neutralino, with decays into photon+Goldstino, and Z+Goldstino. This decay can be chosen prompt, delayed, or quasi-stable. Squarks are relatively very heavy. The second lightest neutralino has a significant branching fraction into h when kinematically allowed.

Model Line F: Focus Point mSUGRA. This model line features squarks and sleptons that are both relatively very heavy.

Model Line G: Anomaly Mediated SUSY breaking The LSP and NLSP are a nearly degenerate neutral and charged wino, respectively. The NLSP chargino decays to the LSP neutralino and very soft pion with a macroscopic decay length as much as 10 cm. Squarks are relatively very heavy.

Model Line H: Coannihilation region mSUGRA This is a typical mSUGRA model line with m_0 rather small compared to m_1/2. It goes through the Battaglia et al Point C.
