PDF reweighting in the Hessian matrix approach

“…As the reweighting penalty P ≈ 21 is less than ∆χ 2 CTEQ6.6 (68%), we conclude that these data could have been added to the CTEQ6.6 fit without causing a significant disagreement with the original data. In this sense these data are compatible with the CTEQ6.6 PDFs despite the largish χ 2 /N data ≈ 1.75 which could hint, however, that some tension between the Tevatron Run-1 jet data [39,40] (used in CTEQ6.6 fit to constrain large-x gluons) and these new LHC measurements exist. 5 The line of red points in Figure 10 shows the spectrum of rescaled GK weights.…”

Universal parametrization of jet production based on parton and fragment rapidities

“…In high energy nuclear collisions experimental evidence [18][19][20][21][22] and theoretical arguments [23,24] indi- 5 cate that most jets are produced at low energies (near 3 GeV), and low-energy jets make substantial contributions to hadron production, especially in more-central A-A collisions. Full understanding of nuclear collisions then depends on an accurate description of jet-related 10 hadron production.…”

“…VII. COMPARISON WITH RECENT JET DATA 15 Figure 9 (left panel) shows a comparison between Tevatron jet cross sections [4][5][6] and the reference model. The 0.63 TeV data agree with the reference (dotted curve) and SppS data for higher jet energies near 100 GeV but shift to the left of the dotted curve for lower jet ener-20 gies.…”

“…The model curves terminate at normalized rapidity u = 0.9 or momentum fraction x ≈ 2/3. Left: Tevatron jet spectra for three energies (points, [4][5][6]) compared to the spectrum reference system (dashed and dotted curves). Right: LHC jet spectra for 7 TeV p-p collisions (points, [7-9]) compared to the spectrum reference system.…”

“…At the Tevatron, however, only a subset of analyses done with the k T jet algorithm [6][7][8][9] are collinear-and infrared-safe. Nonetheless, the inclusive jet measurements with jet size parameters R on the order of unity performed by the CDF [10][11][12] and D0 [13-15] Collaborations at 1.8 and 1.96 TeV center-of-mass energies are well described by NLO QCD calculations. Even though calculations at NLO provide at most three partons in the final state for jet clustering, measurements with somewhat smaller anti-k T jet radii of R = 0.4 up to 0.7 by the ATLAS [16,17], CMS [18][19][20], and ALICE [21] Collaborations are equally well characterized for 2.76 and 7 TeV center-of-mass energies at the LHC.…”
