EXOTIC HEAVY-QUARK CONTRIBUTION IN HADRON-HADRON PRODUCTION OF W- PAIRS(W)

In this paper we study the contribution of new possible heavy quarks t o the process hadron-hadron -->W(+)W(-)X. We consider new exotic quark s as proposed in three extended electroweak models: the vector singlet model (VSM), the vector doublet model (VDM), and the fermion-mirror-f ermion model (FMFM). We discuss the high energy unitarity behavior for the elementary process and their implications. We present the predict ions of the exotic quark contribution for the CERN Large Hadron Collid er (LHC). We present some distributions that can separate the standard model contribution from the new exotic quark contribution.
