摘要：

The first evidence for the top quark at the Tevatron may indicate a cross section higher than the QCD expectation. We consider the possibility that isosinglet heavy quarks may be contributing to the signal and discuss ways of testing this possibility. For example, a charge 2/3 singlet quark, approximately degenerate and mixing with the top quark, would effectively double the standard top signals. A similarly heavy charge -1/3 singlet quark mixing with the bottom quark would not affect top signals but would generate excess Z + multijet events with a b-tag.
