Abstract
Abstract: A study of events containing at least four high transverse momentum jets and a search for double parton scattering (DPS) have been performed using data collected with the UA2 detector at the CERN pp Collider (√s=630 GeV). The results are in good agreement with leading order QCD calculations. A value of σDPS<0.82 nb at 95% confidence level (CL) is obtained for the DPS cross section.

The results are in good agreement with leading order QCD calculations. A value of σDPS<0.82 nb at 95% confidence level (CL) is obtained for the DPS cross section.</div></front></TEI><istex><corpusName>elsevier</corpusName><keywords><teeft><json:string>phys</json:string><json:string>parton</json:string><json:string>collider</json:string><json:string>present address</json:string><json:string>physics letters</json:string><json:string>collab</json:string><json:string>october</json:string><json:string>partons</json:string><json:string>fisica</json:string><json:string>hadronic</json:string><json:string>calorimeter</json:string><json:string>monte carlo simulation</json:string><json:string>collider physics</json:string><json:string>calorimeter response</json:string><json:string>invariant mass</json:string><json:string>transverse energy</json:string><json:string>double parton</json:string><json:string>matrix elements</json:string><json:string>good agreement</json:string><json:string>matrix</json:string><json:string>simulation</json:string><json:string>carlo</json:string><json:string>exact calculation</json:string><json:string>structure functions</json:string><json:string>final state</json:string><json:string>esfag approximation</json:string><json:string>monte carlo simulations</json:string><json:string>systematic uncertainties</json:string><json:string>detector</json:string><json:string>approximate calculations</json:string><json:string>hadronic showers</json:string><json:string>total inelastic</json:string><json:string>topical workshop</json:string><json:string>effective structure function</json:string><json:string>effective structure function approximation</json:string><json:string>same bunch</json:string><json:string>final state partons</json:string><json:string>parton level</json:string><json:string>fisica nucleare</json:string><json:string>multilayer sandwiches</json:string><json:string>theoretical uncertainty</json:string><json:string>detector modelling</json:string><json:string>data samples</json:string><json:string>solid histogram</json:string><json:string>space angles</json:string><json:string>solid histograms</json:string><json:string>statistical errors</json:string><json:string>order calculation</json:string><json:string>full detector simulation</json:string><json:string>data points</json:string><json:string>absolute prediction</json:string><json:string>solid lines</json:string><json:string>systematic uncertainty</json:string><json:string>statistical error</json:string><json:string>france dipartimento</json:string><json:string>multiple interactions</json:string><json:string>double bremsstrahlung</json:string><json:string>systematic errors</json:string><json:string>absolute energy scale</json:string><json:string>final states</json:string><json:string>tree level contributions</json:string><json:string>approximate expressions</json:string></teeft></keywords><author><json:item><name>J.

The results are in good agreement with leading order QCD calculations. A value of σDPS>0.82 nb at 95% confidence level (CL) is obtained for the DPS cross section.</abstract><qualityIndicators><score>7.792</score><pdfWordCount>6606</pdfWordCount><pdfCharCount>30919</pdfCharCount><pdfVersion>1.2</pdfVersion><pdfPageCount>10</pdfPageCount><pdfPageSize>540 x 742 pts</pdfPageSize><refBibsNative>true</refBibsNative><abstractWordCount>66</abstractWordCount><abstractCharCount>394</abstractCharCount><keywordCount>0</keywordCount></qualityIndicators><title>A study of multi-jet events at the CERN pp collider and a search for double parton scattering</title><pii><json:string>0370-2693(91)90937-L</json:string></pii><corporate><json:item><name>UA2 Collaboration</name></json:item></corporate><genre><json:string>research-article</json:string></genre><host><title>Physics Letters B</title><language><json:string>unknown</json:string></language><publicationDate>1991</publicationDate><issn><json:string>0370-2693</json:string></issn><pii><json:string>S0370-2693(00)X1081-7</json:string></pii><volume>268</volume><issue>1</issue><pages><first>145</first><last>154</last></pages><genre><json:string>journal</json:string></genre></host><namedEntities><unitex><date><json:string>1988</json:string><json:string>1989</json:string><json:string>1991</json:string></date><geogName></geogName><orgName><json:string>University of California, Santa Cruz</json:string><json:string>Engineering Research Council</json:string><json:string>Australia CERN, CH</json:string><json:string>Australian Research Council</json:string><json:string>Nuclear Physics Laboratory, University of Oxford, Oxford OX</json:string><json:string>France Dipartimento</json:string><json:string>Italy Laboratoire</json:string><json:string>University of Tsukuba</json:string><json:string>Switzerland Laboratoriumj</json:string><json:string>University of Stockholm</json:string><json:string>Istituto Nazionale</json:string><json:string>C R A Pty Ltd</json:string><json:string>Lawrence Berkeley Laboratory, Berkeley, CA</json:string><json:string>Canvendish Laboratory, University of Cambridge, Cambridge CB</json:string><json:string>Italy School of Physics, University of Melbourne, Parkville</json:string></orgName><orgName_funder></orgName_funder><orgName_provider></orgName_provider><persName><json:string>C.

The results are in good agreement with leading order QCD calculations. A value of σDPS<0.82 nb at 95% confidence level (CL) is obtained for the DPS cross section.</abstract><note>Bern-Cambridge-CERN-Dortmund-Heidelberg-Melbourne-Milano-Orsay (LAL)-Pavia- Perugia-Pisa-Saclay (CEN)</note><relatedItem type="host"><titleInfo><title>Physics Letters B</title></titleInfo><titleInfo type="abbreviated"><title>PLB</title></titleInfo><genre type="journal" authority="ISTEX" authorityURI="https://publication-type.data.istex.fr" valueURI="https://publication-type.data.istex.fr/ark:/67375/JMC-0GLKJH51-B">journal</genre><originInfo><publisher>ELSEVIER</publisher><dateIssued encoding="w3cdtf">19911003</dateIssued></originInfo><identifier type="ISSN">0370-2693</identifier><identifier type="PII">S0370-2693(00)X1081-7</identifier><part><date>19911003</date><detail type="volume"><number>268</number><caption>vol.</caption></detail><detail type="issue"><number>1</number><caption>no.</caption></detail><extent unit="issue-pages"><start>1</start><end>154</end></extent><extent unit="pages"><start>145</start><end>154</end></extent></part></relatedItem><identifier type="istex">B3094658912FEFC5BBBF2F02B675C272C7009B11</identifier><identifier type="ark">ark:/67375/6H6-X2CX0Z0B-6</identifier><identifier type="DOI">10.1016/0370-2693(91)90937-L</identifier><identifier type="PII">0370-2693(91)90937-L</identifier><recordInfo><recordContentSource authority="ISTEX" authorityURI="https://loaded-corpus.data.istex.fr" valueURI="https://loaded-corpus.data.istex.fr/ark:/67375/XBH-HKKZVM7B-M">elsevier</recordContentSource></recordInfo></mods><json:item><extension>json</extension><original>false</original><mimetype>application/json</mimetype><uri>https://api.istex.fr/document/B3094658912FEFC5BBBF2F02B675C272C7009B11/metadata/json</uri></json:item></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
