Light-jet squared mass


Definition of the observable

The squared light jet mass is defined as

$\displaystyle M_l^2 \equiv \min\left\{M_R^2, M_L^2\right\}\>,$ (19)

where $ M_R^2$, $ M_L^2$ are the single hemisphere squared masses defined in (18).

The light jet mass has been studied in [11].

Born event used for the analysis

The hard scale (Q) is taken to be the center-of-mass energy.
Born parton energy fractions (2E/Q) are 0.800, 0.700 and 0.500.

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.
