We present a study of rates and kinematical properties of lepton pairs contained in central jets with transverse energy E{sub T}{>=}15 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{yields}lcX with c{yields}lsX) are the major source of such lepton pairs.
