Abstract
We report on a study of diffractive dijet production in p̅p collisions at √s=1.96 TeV using the CDF II detector at the Fermilab Tevatron p̅p collider. A data sample from 310 pb[superscript -1] of integrated luminosity collected by triggering on a high transverse energy jet, E[subscript T[superscript jet]], in coincidence with a recoil antiproton detected in a Roman pot spectrometer is used to measure the ratio of single-diffractive to inclusive-dijet event rates as a function of x[superscript p̅] of the interacting parton in the antiproton, the Bjorken-x, x[subscript Bj][superscript p̅] , and a Q2≈(E[subscript T][superscript jet])[superscript 2] in the ranges 10[superscript -3]-4 GeV[superscript 2]. The t[subscript p̅] dependence is measured as a function of Q[superscript 2] and x[subscript Bj][superscript p̅] and compared with that of inclusive single diffraction dissociation. We find weak x[subscript Bj][superscript p̅] and Q[superscript 2] dependencies in the ratio of single diffractive to inclusive event rates, and no significant Q[superscript 2] dependence in the diffractive t[subscript p̅] distributions.
