Pre-equilibrium charm quark dynamics and their impact on D-Meson observables

Key Points

• The aim is to investigate how pre-equilibrium evolution affects charm quark dynamics and D-meson observables in heavy ion collisions.
• Analyzed charm quark Raa and v2 in Pb+Pb collisions at √sNN = 5.02 TeV.
• Studied pre-equilibrium evolution and its diffusion characteristics.
• Significant diffusion observed in the charm quark during pre-equilibrium evolution.
• No measurable impact on final state observables was detected.
