Abstract
The dimuon and dielectron data from the Tevatron collider are used to probe for heavy quarks, which decay dominantly via flavour changing neutral current. Depending on whether the decay occurs at the tree or loop level, one gets a lower mass limit of 85 or 75 GeV. The former applies to singlet, vector doublet and mirror type quarks while the latter applies to a lefthanded quark doublet of the fourth generation.
