Mass (normalized to E)


Definition of the observable

We consider the invariant squared jet mass defined as

$\displaystyle \rho \equiv \frac {\left(\sum_{i \in {\cal H}_{\mathrm{C}}} p_i\r...
...2}{4 \left(\sum_{i \in {\cal H}_{\mathrm{C}}} \vert\vec{p}_i\vert\right)^2 }\>,$ (7)

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.
