(1) Observables involving products of four or more momenta arising from energy correlations between four or more detectors do not appear to have any immediate application [5].
(2) Note that the 
vanish for 
outside the range 
to 
(triangle inequality) or if the sum 
is odd and two of the 
are equal (symmetry property of the 3-
symbols).
(3) If the plane formed by the 
and 
axes is chosen to be in the plane of the event, the from (3) all the 
are real so that the deduced from (5) will also be real.
(4) 
denotes the sum of the processes 
and 
, calculated through 
. According to QCD, 
should be the dominant process away from resonances. Details are given in [1].
