Abstract
Abstract: The spin asymmetry in deep inelastic scattering of longitudinally polarised muons by longitudinally polarised protons has been measured in the range 0.01<×<0.7. The spin dependent structure function g1(x) for the proton has been determined and, combining the data with earlier SLAC measurements, its integral over x found to be 0.126±0.010(stat.)±0.015(syst.), in disagreement with the Ellis-Jaffe sum rule. Assuming the validity of the Biorken sum rule, this result implies a significant negative value for the integral of g1 for the neutron. These integrals lead to the conclusion, in the naïve quark parton model, that the total quark spin constitutes a rather small fraction of the spin of the nucleon. Results are also presented on the asymmetries in inclusive hadron production which are consistent with the above picture.

inelastic scattering of longitudinally polarised muons by longitudinally polarised protons has been measured in the range 0.01<×<0.7. The spin dependent structure function g1(x) for the proton has been determined and, combining the data with earlier SLAC measurements, its integral over x found to be 0.126±0.010(stat.)±0.015(syst.), in disagreement with the Ellis-Jaffe sum rule. Assuming the validity of the Biorken sum rule, this result implies a significant negative value for the integral of g1 for the neutron. These integrals lead to the conclusion, in the naïve quark parton model, that the total quark spin constitutes a rather small fraction of the spin of the nucleon. Results are also presented on the asymmetries in inclusive hadron production which are consistent with the above picture.</div></front></TEI><istex><corpusName>elsevier</corpusName><keywords><teeft><json:string>phys</json:string><json:string>polarisation</json:string><json:string>quark</json:string><json:string>polarised</json:string><json:string>radiative</json:string><json:string>muon</json:string><json:string>asymmetry</json:string><json:string>slac</json:string><json:string>nucleon</json:string><json:string>ashman</json:string><json:string>lett</json:string><json:string>present address</json:string><json:string>proton</json:string><json:string>nucl</json:string><json:string>photon</json:string><json:string>inelastic</json:string><json:string>hadron</json:string><json:string>unpolarised</json:string><json:string>ammonia</json:string><json:string>systematic errors</json:string><json:string>parameterisation</json:string><json:string>systematic error</json:string><json:string>radiative corrections</json:string><json:string>parton</json:string><json:string>dilution factor</json:string><json:string>longitudinally</json:string><json:string>bjorken</json:string><json:string>subsect</json:string><json:string>univ</json:string><json:string>preprint</json:string><json:string>structure function</json:string><json:string>target polarisations</json:string><json:string>target cell</json:string><json:string>slac data</json:string><json:string>neutron</json:string><json:string>structure functions</json:string><json:string>free protons</json:string><json:string>depolarisation factor</json:string><json:string>target material</json:string><json:string>naive quark parton model</json:string><json:string>deep inelastic</json:string><json:string>target cells</json:string><json:string>free proton asymmetry</json:string><json:string>corrections</json:string><json:string>final results</json:string><json:string>proton polarisation</json:string><json:string>valence quarks</json:string><json:string>quark flavours</json:string><json:string>polarised target</json:string><json:string>nuovo cimento</json:string><json:string>monte carlo simulation</json:string><json:string>beam flux</json:string><json:string>laboratory frame</json:string><json:string>beam polarisation</json:string><json:string>radiative effects</json:string><json:string>vacuum polarisation</json:string><json:string>total radiative correction</json:string><json:string>unpolarised correction</json:string><json:string>normalisation uncertainty</json:string><json:string>strange quarks</json:string><json:string>polarised protons</json:string><json:string>correction</json:string><json:string>total data sample</json:string><json:string>drift chambers</json:string><json:string>beam direction</json:string><json:string>beam region</json:string><json:string>target halves</json:string><json:string>virtual photon asymmetry</json:string><json:string>polarisation reversal</json:string><json:string>first order</json:string><json:string>false asymmetries</json:string><json:string>target proton</json:string><json:string>good representation</json:string><json:string>beam phase space</json:string><json:string>dependent structure function</json:string><json:string>highest hydrogen content</json:string><json:string>opposite directions</json:string><json:string>nitrogen nucleus</json:string><json:string>magnetic field</json:string><json:string>various sources</json:string><json:string>radiative correction</json:string><json:string>polarised proton correction</json:string><json:string>polarised nitrogen correction</json:string><json:string>muon beam direction</json:string><json:string>longitudinally polarised protons</json:string><json:string>target volume</json:string><json:string>experiment slac</json:string><json:string>lower values</json:string><json:string>good agreement</json:string><json:string>total error</json:string><json:string>total sample</json:string><json:string>smooth curve</json:string><json:string>dilution factors</json:string><json:string>integral converges</json:string><json:string>proton table</json:string><json:string>standard deviation</json:string><json:string>measurement region</json:string><json:string>unmeasured region</json:string><json:string>permanent address</json:string><json:string>triangle anomaly</json:string><json:string>longitudinally polarised muons</json:string><json:string>nuclear studies</json:string><json:string>virtual photon</json:string><json:string>kaur model</json:string><json:string>yale univ</json:string><json:string>schematic diagram</json:string><json:string>target polarisation</json:string></teeft></keywords><author><json:item><name>J.

The spin dependent structure function g1(x) for the proton has been determined and, combining the data with earlier SLAC measurements, its integral over x found to be 0.126±0.010(stat.)±0.015(syst.), in disagreement with the Ellis-Jaffe sum rule. Assuming the validity of the Biorken sum rule, this result implies a significant negative value for the integral of g1 for the neutron. These integrals lead to the conclusion, in the naïve quark parton model, that the total quark spin constitutes a rather small fraction of the spin of the nucleon. Results are also presented on the asymmetries in inclusive hadron production which are consistent with the above picture.</abstract><qualityIndicators><refBibsNative>true</refBibsNative><abstractWordCount>127</abstractWordCount><abstractCharCount>838</abstractCharCount><keywordCount>0</keywordCount><score>8.524</score><pdfWordCount>12565</pdfWordCount><pdfCharCount>58492</pdfCharCount><pdfVersion>1.2</pdfVersion><pdfPageCount>35</pdfPageCount><pdfPageSize>468 x 684 pts</pdfPageSize></qualityIndicators><title>An investigation of the spin structure of the proton in deep inelastic scattering of polarised muons on polarised protons</title><pii><json:string>0550-3213(89)90089-8</json:string></pii><corporate><json:item><name>The European Muon Collaboration</name></json:item></corporate><genre><json:string>research-article</json:string></genre><host><title>Nuclear Physics, Section B</title><language><json:string>unknown</json:string></language><publicationDate>1989</publicationDate><issn><json:string>0550-3213</json:string></issn><pii><json:string>S0550-3213(00)X0496-8</json:string></pii><volume>328</volume><issue>1</issue><pages><first>1</first><last>35</last></pages><genre><json:string>journal</json:string></genre></host><namedEntities><unitex><date><json:string>1989</json:string></date><geogName></geogName><orgName><json:string>University of Oxford</json:string><json:string>Appleton Laboratory, Chilton, Didcot OXI OQX, UK</json:string><json:string>Department of Phvsicw, University of Lancaster, Lancaster LA</json:string><json:string>University of Liverpool</json:string><json:string>Yale University</json:string><json:string>CERN</json:string></orgName><orgName_funder><json:string>CERN</json:string></orgName_funder><orgName_provider></orgName_provider><persName><json:string>J.

The spin dependent structure function g1(x) for the proton has been determined and, combining the data with earlier SLAC measurements, its integral over x found to be 0.126±0.010(stat.)±0.015(syst.), in disagreement with the Ellis-Jaffe sum rule. Assuming the validity of the Biorken sum rule, this result implies a significant negative value for the integral of g1 for the neutron. These integrals lead to the conclusion, in the naïve quark parton model, that the total quark spin constitutes a rather small fraction of the spin of the nucleon. Results are also presented on the asymmetries in inclusive hadron production which are consistent with the above picture.</p></abstract></profileDesc><revisionDesc><change

The spin dependent structure function <ce:italic>g</ce:italic><ce:inf>1</ce:inf>(<ce:italic>x</ce:italic>) for the proton has been determined and, combining the data with earlier SLAC measurements, its integral over <ce:italic>x</ce:italic> found to be 0.126±0.010(stat.)±0.015(syst.), in disagreement with the Ellis-Jaffe sum rule. Assuming the validity of the Biorken sum rule, this result implies a significant negative value for the integral of <ce:italic>g</ce:italic><ce:inf>1</ce:inf> for the neutron. These integrals lead to the conclusion, in the naïve quark parton model, that the total quark spin constitutes a rather small fraction of the spin of the nucleon.

The spin dependent structure function g1(x) for the proton has been determined and, combining the data with earlier SLAC measurements, its integral over x found to be 0.126±0.010(stat.)±0.015(syst.), in disagreement with the Ellis-Jaffe sum rule. Assuming the validity of the Biorken sum rule, this result implies a significant negative value for the integral of g1 for the neutron. These integrals lead to the conclusion, in the naïve quark parton model, that the total quark spin constitutes a rather small fraction of the spin of the nucleon. Results are also presented on the asymmetries in inclusive hadron production which are consistent with the above picture.</abstract><relatedItem type="host"><titleInfo><title>Nuclear Physics, Section B</title></titleInfo><titleInfo type="abbreviated"><title>NUPHB</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">19891211</dateIssued></originInfo><identifier type="ISSN">0550-3213</identifier><identifier type="PII">S0550-3213(00)X0496-8</identifier><part><date>19891211</date><detail type="volume"><number>328</number><caption>vol.</caption></detail><detail type="issue"><number>1</number><caption>no.</caption></detail><extent unit="issue-pages"><start>1</start><end>316</end></extent><extent unit="pages"><start>1</start><end>35</end></extent></part></relatedItem><identifier type="istex">2E06F2E8FB66D1C37B98172413B5C8DE7F4A991E</identifier><identifier type="ark">ark:/67375/6H6-KMQ59FLZ-Z</identifier><identifier type="DOI">10.1016/0550-3213(89)90089-8</identifier><identifier type="PII">0550-3213(89)90089-8</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/2E06F2E8FB66D1C37B98172413B5C8DE7F4A991E/metadata/json</uri></json:item></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
