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.
