Abstract
Abstract: We present results on inelastic J/ψ production from muon interactions with hydrogen and deuterium at an incident muon energy of 280 GeV. The measured cross section ratio per nucleon for muon-induced Jψ production in deuterium and hydrogen was found to be R(D2/H2) = 1.01±0.15. The colour singlet model is shown to provide a good description of the observed differential cross section apart from a normalisation factor. The comparison between the observed cross section and the colour singlet model prediction allows the extraction of the gluon structure function G(x) of the nucleon. The momentum fraction x of the nucleon carried by the gluon is measured in the range of x = [0.02, 0.30]. The normalised gluon distribution of free nucleons thus found can be parametrised as xG(x) = 12 (η+1) (1−x)η, withη=5+-9(sta.).

The measured cross section ratio per nucleon for muon-induced Jψ production in deuterium and hydrogen was found to be R(D2/H2) = 1.01±0.15. The colour singlet model is shown to provide a good description of the observed differential cross section apart from a normalisation factor. The comparison between the observed cross section and the colour singlet model prediction allows the extraction of the gluon structure function G(x) of the nucleon. The momentum fraction x of the nucleon carried by the gluon is measured in the range of x = [0.02, 0.30]. The normalised gluon distribution of free nucleons thus found can be parametrised as xG(x) = 12 (η+1) (1−x)η, withη=5+-9(sta.).</div></front></TEI><affiliations><list><country><li>Allemagne</li><li>Australie</li><li>Belgique</li><li>France</li><li>Italie</li><li>Japon</li><li>Royaume-Uni</li><li>Suisse</li><li>Suède</li><li>États-Unis</li></country><region><li>Bade-Wurtemberg</li><li>Californie</li><li>Canton de Neuchâtel</li><li>District de Cologne</li><li>District de Karlsruhe</li><li>Indiana</li><li>Pennsylvanie</li><li>Rhénanie-Palatinat</li><li>Rhénanie-du-Nord-Westphalie</li><li>Région de Bruxelles-Capitale</li><li>Victoria (État)</li><li>Virginie</li></region><settlement><li>Bruxelles</li><li>Cologne</li><li>Heidelberg</li><li>Juliers</li><li>Mayence</li><li>Melbourne</li><li>Neuchâtel</li></settlement><orgName><li>Université de Melbourne</li><li>Université de Neuchâtel</li></orgName></list><tree><noCountry><name sortKey="Badelek, B" sort="Badelek, B" uniqKey="Badelek B" first="B." last="Badelek">B.
