Abstract
We critically reanalyze some recent experimental data on the Bose-Einstein (BE) correlations in pion production. We show that there is, in some cases, an experimental evidence for a peak height of the correlation function greater than two, contrarily to the predictions of the "canonical" theory of BE correlations. Although an explanation of such an "anomalous" value can be given by means of suitable phenomenological models, we show that this result is a straightforward consequence of the treatment of BE correlations within the framework of a description of strong interactions in terms of a deformed Minkowski metric.
