Abstract

Two-pion correlations are studied for pions of like charge in K+p and π+p collisions at 250 GeV/c. An enhanced production is observed at small momentum difference and is attributed to Bose-Einstein interference between identical particles. A systematic study is presented on the influence of parametrization and reference sample. Interpreted in terms of the Kopylov-Podgoretskii parametrization a size of the emitting region rK≈1.4 fm is found. The Lorentz invariant parametrization of Goldhaber gives rG≈0.8 fm. With fixed parametrization, similarity is found for hadronhadron, e+e- and lepton-hadron collisions. No multiplicity or angular dependence is found at our energy.
