Jade-E 3-jet resolution y3


Definition of the observable

$ y_3$ in the Jade algorithm in the E-scheme is defined by the procedure in 15.1, with the definition of $ y_{ij}$ in (22) is replaced by (27) and the recombination procedure in (23) is replaced by (25).

Born event used for the analysis

The hard scale (Q) is taken to be the center-of-mass energy.

opt. probe region exists F

Information regarding the presence of possible zeros

No zeroes or small values found. Since this observable does not exponentiate, multiple emission effects have not been computed.
