Abstract
An investigation of Bose-Einstein correlations amongst like-charged pi ons produced in muon-nucleon interactions at 490 GeV is presented. On top of a broader enhancement, a steep increase in the correlations at small four-momentum differences between the two pions is observed whic h may be explained by the contribution from decays of resonances (rho- mesons). A two-dimensional analysis discriminates between two differen t parametrizations of the Bose-Einstein effect, strongly favoring the Lorentz-invariant parametrization over a parametrization based on a Ga ussian source distribution in space and time.
