Abstract
We show that a new strongly interacting sector can produce large enhancements of the asymmetries at the Tevatron. The Standard Model is extended by a new vectorlike flavor triplet of fermions and one heavy scalar, all charged under a hypercolor gauge group . This simple extension results in a number of new resonances. The predictions of our model are rather rigid once a small number of UV parameters is fixed, since all the strong dynamics can be directly taken over from our understanding of QCD dynamics. Despite the rather low hypercolor confinement scale of , the new strongly interacting sector is stealth. It is shielded from present direct and indirect New Physics searches since the light resonances are QCD singlets, whereas the production of the heavier QCD colored resonances leads predominantly to high-multiplicity final states. Improved searches can potentially be devised using top tagged final states or decays into a small number of hypercolor pions.
