The Ratio of the Direct Photon Production Cross Section at 630 GeV and at 1800 GeV
نویسنده
چکیده
We measure the ratio of the isolated direct photon prodution cross section at √ s = 630 GeV to that at √ s = 1800 GeV for the central (|η| < 0.9) and forward (1.6 < |η| < 2.5) rapidity regions. We compare the result with next to leading order QCD predictions using CTEQ parton distribution functions.

The Ratio of the Direct Photon
We measure the ratio of the isolated direct photon prodution cross section at p s = 630 GeV to that at p s = 1800 GeV for the central (jj < 0:9) and forward (1:6 < jj < 2:5) rapidity regions. We compare the result with next to leading order QCD predictions using CTEQ parton distribution functions.
متن کاملJets in p̄p Collisions at √ s = 630 and 1800 GeV
Results are presented from analyses of jet data produced in pp collisions at √ s = 630 and 1800 GeV collected with the DØ detector during the 1994–95 Fermilab Tevatron Collider run. We discuss details of detector calibration, and jet selection criteria in measurements of various jet production cross sections at √ s = 630 and 1800 GeV. The inclusive jet cross sections, the dijet mass spectrum, t...

We have made a precise measurement of the inclusive jet cross section at √ s=1800 GeV. The result is based on an integrated luminosity of 92 pb −1 collected at the Fermilab Tevatron pp Collider with the DØ detector. The measurement is reported as a function of jet transverse energy (60 GeV ≤ ET ≤ 500 GeV), and in the pseudo-rapidity intervals |η| ≤ 0.5 and 0.1≤ |η| ≤0.7. A preliminary measureme...
متن کاملRatio of Scaled
Results from the analysis of data collected at the Tevatron pp collider at center of mass energies p s = 630 and 1800 GeV collected by the DD and CDF experiments are presented. Measurements of the inclusive production jet cross section, the inclusive dijet mass spectrum, the triple diierential dijet cross section, and the dijet angular distribution are compared to order 3 s QCD predictions.
