“…We showed that in the absence of any excess of events CDF and DØ individually should be able to probe e ± u (e ± d) leptoquark masses up to 265 (245) GeV for Yukawa couplings of the electromagnetic strength and β = 1. In the case β = 0.5 these limits reduce to 250 (235) represent an improvement over the present bounds obtained at the Tevatron [5], however, the bounds are similar to the ones obtained by the HERA collaborations [7].…”

“…At the hadron colliders, leptoquarks can be pair produced by gluon-gluon and quark-quark fusions, as well as singly produced in association with a lepton in gluon-quark reactions. At the Tevatron, the CDF and DØ collaborations studied the pair production of leptoquarks which decay into electron-jet pairs [5]. The combined CDF and DØ limit on the leptoquark mass is M lq > 242 GeV [6] for scalar leptoquarks decaying exclusively into e ± -jet pairs.…”

We study single production of first generation leptoquarks in association with e Ϯ at the Fermilab Tevatron. We focus our attention on final states exhibiting an e ϩ e Ϫ pair and jets, and perform a detailed analysis of the signal and background. The single leptoquark production cross section depends on the leptoquark Yukawa coupling to lepton-quark pairs and we show that the study of this mode can extend considerably the leptoquark search for a large range of these couplings. In fact, for Yukawa couplings of electromagnetic strength, the combined results of the Tevatron experiments can exclude the existence of leptoquarks with masses up to 260-285 ͑370-425͒ GeV at the run I ͑run II͒, depending on their type.

“…Measurements of the b quark production cross section and bb correlations in pp collisions provide an important test of perturbative quantum chromodynamics (QCD) at next-toleading order (NLO). The measured b quark production cross section at √ s = 1.8 TeV [1][2][3][4] is systematically larger than the central values of the NLO QCD predictions [5,6].…”

“…In this article we choose to concentrate our attention on the cross section d 2 σ/dQ 2 dy with Q 2 being the mass squared and y the rapidity of the produced lepton pair. Most recently the CDF collaboration have studied the rapidity dependence of the Drell-Yan cross section in a limited rapidity range [3]. In fact from the experimental side there is a wealth of data on various rapidity distributions (see Ref.…”
