  A statistical field theory of particle production is presented using a
gaussian functional in three dimensions. Identifying the field with the
particle density fluctuation results in zero correlations of order three and
higher, while the second order correlation function is of a Yukawa form. A
detailed scheme for projecting the theoretical three-dimensional correlation
onto data of three and fewer dimensions illustrates how theoretical predictions
are tested against experimental moments in the different dimensions. An example
given in terms of NA35 parameters should be testable against future NA35 data.
