Measurements of the pseudorapidity gap and xi distributions for dijet production in diffractive events which are defined by large gaps devoid of activity seen in the ATLAS detector, based on a sample of proton-proton collisions at a centre-of-mass energy of 7 TeV of integrated luminosity of 6.8 nb-1 collected in 2010. The final state consists of two jets found by the anti-kt jet algorithm with transverse momentum greater than 20 GeV and empty regions in the acceptance of the ATLAS detector. The pseudorapidity gap variable, denoted here as DELTA(C=RAPGAP), is defined as the larger of the pseudorapidity regions extending to the limits of the ATLAS detector sensitivity at eta=+-4.8, in which no final state particles are observed above a (transverse) momentum threshold. The xi variable is calculated using M**2/S and for Single Diffraction DELTA(C=RAPGAP)~=-ln(xi). See PLBXX (2015) YY for more details.\n\nThe fiducial region is defined as:\nThe jet finding uses the anti-kt algorithm with radius R=0.6 or R=0.4 \n- all stable particles are used except for muons and neutrinos\n- at least 2 jets with ptJet1 > 20 GeV and ptJet2 > 20 GeV\n- at least 2 jets with |etaJet1| < 4.4 and |etaJet2| < 4.4\n\nThe selection of particles for the gap finding:\n- |etaParticle| < 4.8\n- pParticleNeutral > 0.2 GeV\n- pParticleCharged > 0.5 GeV .or. ptParticleCharged > 0.2 GeV\n- The gap finding: two gaps are formed defined as the regions without particles\nfrom the edge of the calorimeter at eta=4.8 or eta=-4.8. The larger of the two\nis the final gap. \n\nThe selection of particles for the xi calculation:\n- |etaParticle| < 4.8\n- pParticleNeutral > 0.2 GeV\n- pParticleCharged > 0.5 GeV \n- The xi value is calculated as Sum [ptParticle*exp(+-etaParticle)/sqrt(S)] where the sum loops over the particles selected above and the exponential function takes the positive (negative) sign if the gap starts at eta = +4.8 (-4.8).\n\nIn the tables the individual sources of systematic uncertainty are given in per cent and are described as follows:\ndJES = jet energy scale uncertainty\ndJER = jet energy resolution uncertainty\ndJAR = jet angular resolution uncertainty\ndJRE = jet reconstruction efficiency uncertainty\ndClustE = cluster energy scale uncertainty\ndCST = cell significance threshold uncertainty \ndJCE = jet cleaning efficiency uncertainty\ndUnf = unfolding procedure uncertainty\ndMod = model uncertainty\ndTrig = jet trigger efficiency uncertainty\ndtrack = tracking efficiency uncertainty\ndlum = luminosity uncertainty\ndmat = added material uncertainty.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.70762.v1/t1","@type":"Dataset","description":"The cross section differential in the forward rapidity gap size, DELTA(C=RAPGAP), for events with at least two jets of pt...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.70762.v1/t2","@type":"Dataset","description":"The cross section differential in the forward rapidity gap size, DELTA(C=RAPGAP), for events with at least two jets of pt...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.70762.v1/t3","@type":"Dataset","description":"The cross section differential in the fraction of the proton four-momentum carried by the Pomeron, LOG10(C=XI), for events with at...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.70762.v1/t4","@type":"Dataset","description":"The cross section differential in the fraction of the proton four-momentum carried by the Pomeron, LOG10(C=XI), for events with at...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.70762.v1/t5","@type":"Dataset","description":"The cross section differential in the fraction of the proton four-momentum carried by the Pomeron, LOG10(C=XI), for events with at...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.70762.v1/t6","@type":"Dataset","description":"The cross section differential in the fraction of the proton four-momentum carried by the Pomeron, LOG10(C=XI), for events with at...","name":"Table 6"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1402356?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/70762"}],"inLanguage":"en","name":"Dijet production in $\\sqrt{s}=7$ TeV $pp$ collisions with large rapidity gaps at the ATLAS experiment","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1402356?version=1","version":1}
