A Search for Quark Compositeness with the CDF Detector at the Fermilab Collider
- Texas A & M Univ., College Station, TX (United States)
The inclusive jet cross section in $$p\bar{p}$$ collisions at $$\sqrt{s}$$ 1.8 TeV has been measured using jet clustering cone sizes of 0.4, 0.7 and 1.0. The cone size, R, is defined to be, $$R = \sqrt{{\Delta \eta^2 + \Delta \phi^2}}$$ where $$\eta$$ = In tan 0/2, 0 represents the polar angle and represents the azimuthal angle. A lower limit on the value of the composite scale parameter, A was determined lo be 1100 GeV at 95% confidence level using the cone size 1.0. Comparisons to both lea.ding order Quantum Chromo Dyna.mies (QCD) and next-lo-leading order QCD calculations have been made and no significant deviations from QCD observed. The dependence of the inclusive jet cross section on cone size ha.s also been compared to next-to-leading order QCD. The measured cross section was found to grow larger with increasing cone size, more quickly than next-to-leading order QCD predicts.
