* * Normalized top quark pair double-differential cross section as function of M(ttbar) and delta_eta(t,tbar) * The data are taken from arXiv:1703.01630, tables 14, 15 (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 [M(ttbar),delta_eta(t,tbar)] 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_mtt_detatt.txt','datafiles/lhc/cms/topProduction/1703.01630/virtgrid_mtt_detatt.txt', TheorExpr = 'A1/sum(A2)' NData = 12 NColumn = 31 ColumnType = 'Flag',4*'Bin','Sigma',25*'Error' ColumnName = 'binFlag','mttmin','mttmax','detattmin','detattmax','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 = 'mttmin' PlotDefValue = 339.99, 399.99, 499.99, 649.99, 1499.99 PlotVarColumn = 'detattmin' PlotOptions(1) = 'Experiment:#sqrt{s} = 8 TeV t#bar{t} @ExtraLabel:pp #rightarrow t#bar{t} @XTitle: #Delta#eta(t,#bar{t}) @YTitle: #frac{1}{#sigma(t#bar{t})}#frac{d#sigma(t#bar{t})}{d#Delta#eta(t,#bar{t})dM(t#bar{t})} @Title:340 < M(t#bar{t}) < 400 GeV' PlotOptions(2) = 'Experiment:#sqrt{s} = 8 TeV t#bar{t} @ExtraLabel:pp #rightarrow t#bar{t} @XTitle: #Delta#eta(t,#bar{t}) @YTitle: #frac{1}{#sigma(t#bar{t})}#frac{d#sigma(t#bar{t})}{d#Delta#eta(t,#bar{t})dM(t#bar{t})} @Title:400 < M(t#bar{t}) < 500 GeV' PlotOptions(3) = 'Experiment:#sqrt{s} = 8 TeV t#bar{t} @ExtraLabel:pp #rightarrow t#bar{t} @XTitle: #Delta#eta(t,#bar{t}) @YTitle: #frac{1}{#sigma(t#bar{t})}#frac{d#sigma(t#bar{t})}{d#Delta#eta(t,#bar{t})dM(t#bar{t})} @Title:500 < M(t#bar{t}) < 650 GeV' PlotOptions(4) = 'Experiment:#sqrt{s} = 8 TeV t#bar{t} @ExtraLabel:pp #rightarrow t#bar{t} @XTitle: #Delta#eta(t,#bar{t}) @YTitle: #frac{1}{#sigma(t#bar{t})}#frac{d#sigma(t#bar{t})}{d#Delta#eta(t,#bar{t})dM(t#bar{t})} @Title:650 < M(t#bar{t}) < 1500 GeV' &End * Flag mttmin mttmax detattmin detattmax 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 mtt bin 1 340.00 400.00 0.00 0.40 2.008e-01 7.3 2.5 -0.1 -0.9 0.6 0.0 -0.0 0.3 -0.2 -0.0 0.0 -0.4 0.4 0.6 -0.6 0.3 -0.3 -0.7 0.4 -1.1 -0.1 2.0 3.7 6.8 -0.0 1 340.00 400.00 0.40 1.20 1.518e-01 3.2 1.7 -1.7 0.1 -0.5 -0.0 0.0 -0.0 -0.1 -0.1 0.1 -0.4 0.4 0.3 -0.3 -0.3 0.3 -1.6 1.2 -1.1 1.6 -1.3 0.5 -4.2 0.0 1 340.00 400.00 1.20 6.00 1.384e-02 8.4 -0.1 -1.1 0.8 -0.0 -0.0 0.0 0.1 -0.1 0.1 -0.1 -0.4 0.4 -0.3 0.3 -0.1 0.1 -2.5 2.5 3.4 2.3 1.6 -1.1 -3.3 5.1 * 2 mtt bin 1 400.00 500.00 0.00 0.40 1.601e-01 6.2 -2.1 0.4 -1.0 -0.8 0.0 -0.0 0.1 -0.1 0.1 -0.1 0.4 -0.4 -0.0 0.1 0.3 -0.3 0.4 -1.0 -0.8 0.5 0.2 -0.0 3.8 2.4 1 400.00 500.00 0.40 1.20 1.689e-01 3.3 -1.1 0.7 1.1 0.1 -0.0 0.0 -0.1 0.3 -0.1 0.1 0.2 -0.2 -0.1 0.1 -0.1 0.1 0.7 -0.4 1.6 -0.4 0.1 -0.5 -1.1 -1.8 1 400.00 500.00 1.20 6.00 3.869e-02 2.3 -0.9 1.4 -0.3 -0.0 0.0 -0.0 0.1 -0.1 0.1 -0.1 0.1 -0.1 -0.1 0.1 0.1 -0.1 -0.6 1.0 0.4 -1.4 -0.4 -0.5 1.9 -2.4 * 3 mtt bin 1 500.00 650.00 0.00 0.40 5.346e-02 10.7 2.1 0.2 0.8 1.6 0.0 -0.0 -0.2 0.1 0.2 -0.2 0.2 -0.3 -0.1 0.1 0.1 -0.1 2.2 -2.4 -5.6 3.7 2.4 1.8 -0.8 -2.3 1 500.00 650.00 0.40 1.20 5.332e-02 7.7 2.3 -0.1 0.4 -0.7 -0.0 0.0 -0.4 0.6 -0.1 0.1 0.2 -0.1 -0.2 0.2 -0.3 0.3 2.3 -1.6 6.5 3.3 3.9 2.3 -5.4 7.6 1 500.00 650.00 1.20 6.00 3.441e-02 2.4 -0.8 0.1 -0.3 -0.4 0.0 -0.0 0.1 -0.2 -0.0 0.0 0.0 -0.0 0.1 -0.1 -0.0 0.0 0.1 -0.5 -2.1 -2.9 -2.3 -0.6 1.0 -2.6 * 4 mtt bin 1 650.00 1500.00 0.00 0.40 1.768e-02 13.3 1.3 -1.5 -0.8 -1.0 -0.0 0.0 -0.1 0.1 0.0 -0.0 0.4 -0.4 -0.4 0.4 -0.1 0.1 2.0 -2.6 0.1 -3.3 -0.2 -3.3 -8.0 -0.2 1 650.00 1500.00 0.40 1.20 2.055e-02 8.6 1.8 -3.5 -1.7 0.9 0.0 -0.0 0.1 -0.1 0.2 -0.2 0.4 -0.4 0.3 -0.3 0.1 -0.1 2.3 -2.6 -4.6 3.3 -4.3 -1.1 2.2 -6.2 0 650.00 1500.00 1.20 6.00 1.964e-02 3.1 -0.0 -0.4 0.3 1.2 0.0 -0.0 -0.4 0.4 -0.1 0.1 0.1 -0.2 -0.5 0.6 0.0 -0.0 2.1 -1.6 0.1 1.8 2.1 -1.2 -1.3 4.9
