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.
