Definition of the observable
One can consider all particles in a central rapidity region , and
determine the transverse thrust axis
as described in
eq. (2). One then separates the event into an
up region
consisting of all particles in with
and a down region
with all
particles in with
. One then
constructs the normalised sum of the invariant masses of the two regions

(14) 
where
is the total transverse energy in as
defined in eq. (6).
One then looks at the sum of the normalised invariant masses

(15) 
The hard scale (Q) is taken to be the Born partonic centerofmass energy.
Rapidity of the center of mass of the outgoing pair: 0.000
Cosine of the angle between outgoing jet and beam (in the partonic CM frame): 0.200

Since this observable is nonglobal, the analysis has not been continued.
Since this observable is discontinuosly global, multiple emission effects have not been computed.
