Heavy quark diffusion in glasma and gluonic plasma

The research of the pre-equilibrium stage produced in the ultrarelativistic heavy-ion collisions and its evolution to quark-gluon plasma (QGP) is of great interest as it provides insights into the Quantum Chromodynamics (QCD) matter under extreme conditions. The early pre-equilibrium stage of high energy nuclear collisions can be described as a set of dense, colored fields called Glasma which affects the heavy quarks dynamics significantly. We observe the super diffusion of heavy quarks in the early stage of high energy collisions due to the strong, coherent gluon fields and memory effects become influential there
