Thrust with respect to the thrust axis (normalized to E)


Definition of the observable

We consider one minus the thrust with respect to the thrust axis normalised to the current hemisphere energy

$\displaystyle \tau_{tE} \equiv 1- T_{tE} = 1- \max_{\vec{n}} \frac {\sum_{i \in...
...\cdot \vec{n}\vert} {\sum_{i \in {\cal H}_{\mathrm{C}}} \vert\vec{p_i}\vert}\,,$ (10)

This observable has been resummed in [4].

Born event used for the analysis

The hard scale (Q) is taken to be photon virtuality.

Elementary tests on the observable

Test result
check number of jets T
all legs positive T
globalness F

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