Description
We have studied Bose-Einstein correlations for positive pions produced in DIS events with data from experiments carried out during the run period EG2 in Jefferson Lab, Virginia using different targets, such as D2, C, Fe and Pb, exposed to a 5.014 GeV electron beam. By comparing the pairs of π+ from same events to uncorrelated pairs, we can obtain information of the space-time structure and dynamics of the source of the produced bosons. The goal of the study was to measure the size of the π+ production source and its degree of coherence in one and two-dimensional approaches. No significant differences have been found, regarding the size of the pion source along solid targets and clear elongation of the source was found for all nuclear targets with dependence in nuclear number A.
