Searches for BSM (non-SUSY) physics at the Tevatron

The discovery of anomalous behavior in data collected at high energy physics experiments could provide non-SUSY and non-Higgs explanations to questions associated with the Standard Model and provide deeper understanding to the fundamental particles and interactions in nature. Such questions include whether quarks and leptons are composite particles, the existence of extra dimensions, and the answer to the hierarchy problem in the Standard Model (SM). Generally, a search is approached by first understanding the SM prediction for a given signal and detector backgrounds which could mimic that signal. Analyses are optimized for signal, not according to model, prior to looking in the signal region of the data. If no anomalous behavior is found, the signal acceptances of various models can be used to set limits.
