Abstract
Scale invariant presentation of inclusive
spectra
in terms of light front variables is proposed.
The variables introduced go over to the well-known scaling
variables 
and 
in the high pz and high PT limits respectively.
Some surface is found in the phase space
of produced 
-mesons in the inclusive reaction
at 22.4GeV/c, which separates two groups of
particles with significantly different characteristics. In one of these
regions a naive statistical model seems to be in
a good agreement with data, whereas it fails in the second
region.
