Geneva-E 3-jet resolution y3


Definition of the observable

$ y_3$ in the Geneva algorithm in the E-scheme is obtained following the algorithm described in Sec. 15.1, with the resolution parameter defined in (28) and the recombination defined in (25).

Born event used for the analysis

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

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.
