Query: Bose-Einstein Correlations in charged current muon-neutrino interactions
  in NOMAD   Bose-Einstein Correlations in one and two dimensions have been studied in
charged current muon-neutrino interaction events collected with NOMAD. In one
dimension the Bose-Einstein effect has been analyzed with the Goldhaber and the
Kopylov parametrizations. The two-dimensional shape of the source has been
investigated in the longitudinal co-moving frame. A significant difference
between the transverse and the longitudinal sizes is observed.
