Description

Heavy quarks which mix with the Standard Model states appear in many new physics scenarios. We study signatures of such generic heavy quarks at hadron colliders as a function of their mass and mixing. We explore the interesting channel of single production of heavy quarks via electroweak processes. This channel has improved sensitivity compared to the kinematically suppressed QCD pair production at slightly large masses (where pair production falls rapidly). We find that the current run of the Tevatron with 2 fb-1 integrated luminosity has significant sensitivity for the production of such heavy quarks. One example of a new physics scenario where this analysis is applicable is models of warped extra dimensions with custodial symmetry. Such models have light Kaluza-Klein excitations of the fermions which could lead to possible direct detection of extra dimensions at the Tevatron.
