Probing the Top Quark Flavour-Changing Neutral Current at a Future Electron-Positron Collider

Figure 4

The kinematic distributions of four significance variables used as inputs to BDT in addition to the boson and top mass distributions. (a) The transverse momentum of the charged lepton and (b) transverse momentum of the -jet . (c) The angular separation between charged lepton and -jet and (d) the difference of the azimuthal angle between the reconstructed boson and the -jet .
