A representation of a prompt D$^0$-tagged jet, with the three jet axes (Standard, Soft Drop, and Winner-Takes-All) and the D$^0$ axis. The dead cone is represented by the red cones around the charm quark at each splitting. i) The Standard jet axis is calculated as the sum of the jet constituent four-momenta. ii) The Soft Drop jet axis is determined from the first splitting which passes the Soft Drop condition. In this example, it is satisfied by the second splitting following the charm quark. The first splitting does not satisfy the Soft Drop condition, thus the softer branch is removed. iii) The Winner-Takes-All jet axis aligns with the hardest subjet in the hardest branch at each splitting.
