We present a study of rates and kinematical properties of lepton pairs contained in central jets with transverse energy ET 15GeV 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→lcX with c→lsX) are the major source of such lepton pairs. © 2005 The American Physical Society.
