| الوصف: | Bose-Einstein correlations of like-sign charged hadrons produced in deep-inelastic electron and positron scattering are studied in the HERMES experiment using nuclear targets of H-1, H-2, He-3, He-4, N, Ne, Kr, and Xe. A Gaussian approach is used to parametrize a two-particle correlation function determined from events with at least two charged hadrons of the same sign charge. This correlation function is compared to two different empirical distributions that do not include the Bose-Einstein correlations. One distribution is derived from unlike-sign hadron pairs, and the second is derived from mixing like-sign pairs from different events. The extraction procedure used simulations incorporating the experimental setup in order to correct the results for spectrometer acceptance effects, and was tested using the distribution of unlike-sign hadron pairs. Clear signals of Bose-Einstein correlations for all target nuclei without a significant variation with the nuclear target mass are found. Also, no evidence for a dependence on the invariant mass W of the photon-nucleon system is found when the results are compared to those of previous experiments. ; Ministry of Education and Science of Armenia; FWO-Flanders; IWT, Belgium; Natural Sciences and Engineering Research Council of Canada; National Natural Science Foundation of China; Alexander von Humboldt Stiftung; German Bundesministerium fur Bildung und Forschung (BMBF); Deutsche Forschungsgemeinschaft (DFG); Italian Istituto Nazionale di Fisica Nucleare (INFN); MEXT; JSPS; G-COE of Japan; Dutch Foundation for Fundamenteel Onderzoek der Materie (FOM); Russian Academy of Science; Russian Federal Agency for Science and Innovations; Basque Foundation for Science (IKERBASQUE); UPV/EHU [UFI 11/55]; U.K. Engineering and Physical Sciences Research Council; Science and Technology Facilities Council; Scottish Universities Physics Alliance; U.S. Department of Energy (DOE); National Science Foundation (NSF); DESY management ; SCI(E) ; ARTICLE ; gunar.schnell@desy.de ; 8 ; 75 |
