Figure Caption

The spin density matrix element (\rzz) for prompt and non-prompt \Dstar mesons as a function of \pt in the production (left panel) and helicity (right panel) frames in pp collisions at $\s=13.6~\TeV$. The measurements in the helicity frame are compared with previous results at $\s=13~\TeV$~. All the data points are compared with predictions from the PYTHIA 8 + EvtGen MC generators~.
