A First Top Partner Hunter's Guide

Understand

We provide a systematic effective lagrangian description of the phenomenology of the lightest top-partners in composite Higgs models.

• Our construction is based on symmetry, on selection rules and on plausible dynamical assumptions.
• The structure of the resulting simplified models depends on the quantum numbers of the lightest top partner and of the operators involved in the generation of the top Yukawa.
• In all cases the phenomenology is conveniently described by a small number of parameters, and the results of experimental searches are readily interpreted as a test of naturalness.
