Abstract
We present a study of rates and kinematical properties of lepton pairs contained in central jets with transverse energy ${E}_{T}\ensuremath{\ge}15\text{ }\text{ }\mathrm{GeV}$ that are produced at the Fermilab Tevatron collider. We compare the data to a QCD prediction based on the herwig and qq Monte Carlo generator programs. We find that the data are poorly described by the simulation, in which sequential semileptonic decays of single $b$ quarks ($b\ensuremath{\rightarrow}lcX$ with $c\ensuremath{\rightarrow}lsX$) are the major source of such lepton pairs.
