* * Normalized top quark pair double-differential cross section as function of y(t) and pT(t) * The data are taken from arXiv:1703.01630, tables 5, 6 (Eur.Phys.J. C77 (2017) no.7, 459) [TOP-14-013] * "Measurement of double-differential cross sections for top quark pair production in pp collisions at sqrt(s) = 8 TeV and impact on parton distribution functions" * Treatment of asymmetric systematic uncertainties by splitting into two sources follows description in Section 8.1 of the paper (Eq. 6) * Following systematic uncertainties are omitted: * 1) model systematics due to PDFs (should not be considered in a PDF analysis) * 2) experimenatal systematics due to b tagging (consist of many negligible individual sources, skipping them does not affect the results) * The last bin will be skipped in the fit ('Flag' column), since this is normalised cross section; the results do not depend on which bin is skipped * This cross section is divided by the bin width of the 2nd variable only * * TECHNICAL COMMENT: below Reaction = 'pp jets APPLGRID' is used as a dummy name to enable theory expression treatment * &Data Name = 'CMS 8TeV ttbar [y(t),pT(t)] cross section' IndexDataset = 211 Reaction = 'pp jets APPLGRID' TheoryType = 'expression' TermName = 'A1','A2' TermType = 'virtgrid_normhyperbin','virtgrid_norm' TermSource = 'datafiles/lhc/cms/topProduction/1703.01630/virtgrid_yt_ptt.txt','datafiles/lhc/cms/topProduction/1703.01630/virtgrid_yt_ptt.txt', TheorExpr = 'A1/sum(A2)' NData = 16 NColumn = 31 ColumnType = 'Flag',4*'Bin','Sigma',25*'Error' ColumnName = 'binFlag','ytmin','ytmax','pttmin','pttmax','x-section','stat const','cmstop14013_JES_U:A','cmstop14013_JES_D:A','cmstop14013_JER_U:A','cmstop14013_JER_D:A','cmstop14013_kinRec_U:A','cmstop14013_kinRec_D:A','cmstop14013_pileup_U:A','cmstop14013_pileup_D:A','cmstop14013_trigger_U:A','cmstop14013_trigger_D:A','cmstop14013_backgrGamZ_U:A','cmstop14013_backgrGamZ_D:A','cmstop14013_backgrOther_U:A','cmstop14013_backgrOther_D:A','cmstop14013_luminosity_U:A','cmstop14013_luminosity_D:A','cmstop14013_mt_U:A','cmstop14013_mt_D:A','cmstop14013_mu_U:A','cmstop14013_mu_D:A','cmstop14013_matchingThreshold_U:A','cmstop14013_matchingThreshold_D:A','cmstop14013_Hadronization:A','cmstop14013_hardScattering:A' Percent = 25*true &End &PlotDesc PlotN = 4 PlotDefColumn = 'ytmin' PlotDefValue = -0.01, 0.34, 0.84, 1.44, 2.49 PlotVarColumn = 'pttmin' PlotOptions(1) = 'Experiment:#sqrt{s} = 8 TeV t#bar{t} @ExtraLabel:pp #rightarrow t#bar{t} @XTitle: p_{T}(t) @YTitle: #frac{1}{#sigma(t#bar{t})}#frac{d#sigma(t#bar{t})}{dp_{T}(t)dy(t)} @Title:0 < y(t) < 0.35 GeV' PlotOptions(2) = 'Experiment:#sqrt{s} = 8 TeV t#bar{t} @ExtraLabel:pp #rightarrow t#bar{t} @XTitle: p_{T}(t) @YTitle: #frac{1}{#sigma(t#bar{t})}#frac{d#sigma(t#bar{t})}{dp_{T}(t)dy(t)} @Title:0.35 < y(t) < 0.85 GeV' PlotOptions(3) = 'Experiment:#sqrt{s} = 8 TeV t#bar{t} @ExtraLabel:pp #rightarrow t#bar{t} @XTitle: p_{T}(t) @YTitle: #frac{1}{#sigma(t#bar{t})}#frac{d#sigma(t#bar{t})}{dp_{T}(t)dy(t)} @Title:0.85 < y(t) < 1.45 GeV' PlotOptions(4) = 'Experiment:#sqrt{s} = 8 TeV t#bar{t} @ExtraLabel:pp #rightarrow t#bar{t} @XTitle: p_{T}(t) @YTitle: #frac{1}{#sigma(t#bar{t})}#frac{d#sigma(t#bar{t})}{dp_{T}(t)dy(t)} @Title:1.45 < y(t) < 2.5 GeV' &End * Flag ytmin ytmax pttmin pttmax xsection stat JES_U JES_D JER_U JER_D krc_U krc_D PU_U PU_D trg_U trg_D bGZ_U bGZ_D bOt_U bOt_D lum_U lum_D mt_U mt_D mu_U mu_D mat_U mat_D hadr hscat * 1 yt bin 1 0.00 0.35 0.00 80.00 1.077e-03 4.4 1.9 -0.4 1.5 0.3 0.0 -0.0 0.0 0.0 0.1 -0.1 0.0 0.0 0.0 -0.0 0.1 -0.1 0.5 0.1 -1.9 3.0 2.0 0.6 -3.3 2.1 1 0.00 0.35 80.00 150.00 1.297e-03 3.6 -1.3 -0.7 -0.4 -0.6 0.0 -0.0 0.1 -0.1 0.1 -0.1 0.3 -0.3 0.1 -0.1 0.1 -0.1 -0.7 0.6 -3.0 -1.6 -1.4 -1.4 0.4 -3.2 1 0.00 0.35 150.00 250.00 4.745e-04 5.0 -0.1 -0.4 -0.9 -0.4 -0.0 0.0 -0.1 0.2 0.1 -0.1 0.3 -0.3 -0.1 0.1 -0.0 0.0 0.2 -0.1 0.1 0.5 1.1 2.7 2.7 0.5 1 0.00 0.35 250.00 600.00 3.898e-05 7.7 1.8 -1.0 0.0 -0.0 -0.0 0.0 -0.2 0.1 0.1 -0.1 0.1 -0.1 -0.1 0.1 -0.0 0.0 1.5 -2.3 -4.7 3.5 -4.0 -3.5 -5.9 3.3 * 2 yt bin 1 0.35 0.85 0.00 80.00 1.448e-03 3.2 0.6 -1.1 -0.6 -0.1 -0.0 0.0 -0.1 0.1 0.1 -0.1 -0.3 0.4 0.0 -0.1 -0.1 0.1 0.3 -0.4 0.0 -0.6 -0.4 1.6 1.7 0.1 1 0.35 0.85 80.00 150.00 1.585e-03 3.0 -1.0 0.2 -1.0 -0.4 -0.0 0.0 0.0 -0.1 0.1 -0.1 0.1 -0.1 -0.1 0.0 -0.1 0.1 -0.4 0.7 0.6 -1.2 -1.8 -1.4 -1.8 -0.1 1 0.35 0.85 150.00 250.00 5.834e-04 4.5 1.6 0.6 1.2 1.1 -0.0 0.0 -0.3 0.4 0.1 -0.1 0.1 -0.1 -0.1 0.2 -0.1 0.1 0.3 0.1 3.3 0.1 1.8 -0.4 -2.4 2.9 1 0.35 0.85 250.00 600.00 4.391e-05 8.1 0.2 -2.7 -2.1 0.3 -0.0 0.0 -0.3 0.3 0.1 -0.1 0.3 -0.3 -0.6 0.6 -0.0 0.0 1.6 -2.1 -1.6 1.2 1.0 1.5 2.2 -5.0 * 3 yt bin 1 0.85 1.45 0.00 80.00 1.351e-03 3.4 -1.3 -0.7 -1.0 -1.0 0.0 0.0 0.1 -0.1 -0.0 0.0 -0.1 0.1 0.1 -0.1 -0.1 0.1 0.1 -0.5 1.3 -2.4 -1.1 -1.0 1.5 -0.6 1 0.85 1.45 80.00 150.00 1.394e-03 3.3 -1.3 1.8 0.1 0.8 -0.0 0.0 0.3 -0.4 -0.1 0.1 0.1 -0.1 -0.1 0.1 -0.1 0.1 -0.6 0.8 1.3 0.6 1.8 0.6 0.6 1.4 1 0.85 1.45 150.00 250.00 5.308e-04 4.8 -1.9 -0.7 0.0 -1.2 0.0 -0.0 -0.3 0.4 0.1 -0.1 0.2 -0.3 0.2 -0.3 0.0 -0.0 -0.1 -0.3 -2.5 1.7 0.3 1.1 -5.2 2.6 1 0.85 1.45 250.00 600.00 3.349e-05 9.6 2.7 -1.3 -0.1 2.5 -0.0 0.0 -0.4 0.4 0.1 -0.1 0.4 -0.4 -0.3 0.4 0.0 -0.0 2.0 -1.6 2.2 4.2 2.9 2.6 -1.1 -9.4 * 4 yt bin 1 1.45 2.50 0.00 80.00 9.538e-04 5.6 1.5 2.1 1.9 0.7 0.0 -0.0 0.1 -0.1 -0.3 0.4 -0.4 0.5 0.0 -0.0 0.1 -0.1 0.2 -0.1 -1.0 1.5 -0.1 -0.2 0.0 4.4 1 1.45 2.50 80.00 150.00 1.086e-03 4.5 1.2 0.8 1.3 0.8 0.0 -0.0 0.0 -0.0 -0.2 0.2 -0.1 0.1 -0.0 0.1 0.1 -0.1 -0.4 0.4 2.3 -0.8 0.3 -1.1 4.9 -3.4 1 1.45 2.50 150.00 250.00 3.302e-04 7.9 0.4 -0.8 -2.1 -0.4 -0.0 0.0 0.1 -0.1 -0.3 0.4 0.2 -0.2 0.1 -0.0 -0.1 0.1 -0.2 -0.8 -0.9 0.6 -1.1 2.1 1.7 -5.0 0 1.45 2.50 250.00 600.00 1.632e-05 17.3 1.1 -3.5 1.3 -0.3 0.0 -0.0 -0.6 0.6 -0.1 0.1 0.4 -0.4 -0.1 0.1 0.1 -0.1 3.0 -3.0 1.1 -3.1 1.5 -6.3 -4.3 -10.5
