Short description.

This benchmark is a challenge of reconstructing multi-jet final state with flavour tag and vertex charge. Main focus is currently on 6-jet (bbqqqq) and 4-jet (bbqqlv) final states.

bbbar final state is also being investigated with the same framework.

Main observables.

x-section measured with both beam polarizations, Polar angle (A_FB) measured with both beam polarizations

Control variables.

b-tag, c-tag, vertex charge, dEdx, M_top, M_W,

Physics quantities.

form factors, electroweak couplings, distinction between left- and right-handed couplings,
