Cone thrust minor with exponentially suppressed forward term


Definition of the observable

The cone central thrust minor with exponentially suppressed term is defined as eq. (12), however the region $ {\cal C}$ is defined as in eq. (9).

Born event used for the analysis

The hard scale (Q) is taken to be the Born partonic center-of-mass energy.
Rapidity of the center of mass of the outgoing pair: 0.000
Cosine of the angle between outgoing jet and beam (in the partonic CM frame): 0.200
