Title: Central exclusive dijet production at the Fermilab Tevatron

Abstract

We perform a phenomenological analysis of dijet production in double Pomeron exchange at the Tevatron. We find that the CDF-Run I results do not rule out the presence of an exclusive dijet component, as predicted by Khoze, Martin and Ryskin (KMR). With the high-statistics CDF-Run II data, we predict that an exclusive component at the level predicted by KMR may be visible, although the observation will depend on accurate modeling of the inclusive double Pomeron exchange process. We also compare to the predictions of the DPEMC Monte Carlo, which contains a nonperturbative model for the central exclusive process. We show that the perturbative model of KMR gives different predictions for the dijet E{sub T} dependence in the high dijet mass fraction region than nonperturbative models.

  • The authors present the first observation and cross section measurement of exclusive dijet production in {bar p}p interactions, {bar p}p {yields} {bar p} + dijet + p. Using a data sample of 310 pb{sup -1} collected by the Run II Collider Detector at Fermilab at {radical}s = 1.96 TeV, exclusive cross sections for events with two jets of transverse energy E{sub T}{sup jet} {ge} 10 GeV have been measured as a function of minimum E{sub T}{sup jet}. The exclusive signal is extracted from fits to data distributions based on Monte Carlo simulations of expected dijet signal and background shapes. Themore » simulated background distribution shapes are checked in a study of a largely independent data sample of 200 pb{sup -1} of b-tagged jet events, where exclusive dijet production is expected to be suppressed by the J{sub z} = 0 total angular momentum selection rule. Results obtained are compared with theoretical expectations, and implications for exclusive Higgs boson production at the pp Large Hadron Collider at {radical}s = 14 TeV are discussed.« less

  • We calculate several differential distributions for exclusive double-diffractive {chi}{sub c}(0{sup ++}) production in the proton-antiproton collisions at the Tevatron and in proton-proton collisions at RHIC and LHC. We use unintegrated gluon distributions (UGDFs) within the k{sub t}-factorization approach. The g*g*{yields}{chi}{sub c}(0{sup ++}) transition vertex is calculated as a function of gluon virtualities via the standard perturbative nonrelativistic QCD technique. The off shell effects are discussed and quantified. They lead to a reduction of the cross section by a factor of 2-5, depending on the position in the phase space and UGDFs. Different models of UGDFs are used and the resultsmore » are shown and discussed. The cross section for the diffractive component depends strongly on UGDFs. Transverse momentum distribution of {chi}{sub c}(0) shows a well localized minimum. We calculate also the differential distributions for the {gamma}*{gamma}*{yields}{chi}{sub c}(0{sup ++}) fusion mechanism. The integrated cross section for photon-photon fusion is much smaller than that of diffractive origin. The two components have very different dependence on the momentum transfers t{sub 1}, t{sub 2} in the nucleon lines as well as azimuthal-angle correlations between both outgoing nucleons.« less
  • In this paper, we discuss the observation of exclusive events using the dijet mass fraction as measured by the CDF Collaboration at the Fermilab Tevatron. We compare the data to Pomeron exchange inspired models as well as soft color interaction ones. We also provide the prediction on the dijet mass fraction at the CERN LHC using both exclusive and inclusive diffractive events.
  • We report a new measurement of dijet production by color-singlet exchange in p{ovr p} collisions at {radical}(s)=1.8 TeV at the Fermilab Tevatron. In a sample of events with two jets of transverse energy E{sup jet}{sub T}{gt}20 GeV , pseudorapidity in the range 1.8{lt}{vert_bar}{eta}{sup jet}{vert_bar}{lt}3.5 , and {eta}{sub 1}{eta}{sub 2}{lt}0 , we find that a fraction R=[1.13{plus_minus}0.12(stat){plus_minus} 0.11(syst)]{percent} has a pseudorapidity gap within {vert_bar}{eta}{vert_bar}{lt}1 between the jets that can be attributed to color-singlet exchnage. The fraction R shows no significant dependence on E{sup jet}{sub T} or on the pseudorapidity separation between the jets. {copyright} {ital 1998} {ital The American Physical Society}
