Abstract
Many extensions of the Standard Model include SU(2)L × U(1)Y singlet higgs bosons, h0, and also vectorlike fermions which couple to it. The production and detection possibilities of such singlet neutral scalars at hadron colliders are considered for different scenarios of vectorlike fermions. We find that for some values of masses and couplings, detection at the CERN Large Hadron Collider (LHC) appears to be a distinct possibility, while at the Fermilab Tevatron upgrade the h0 might be observed only in very favourable circumstances.
