Description

The momentum diffusion coefficient controls the Langevin dynamics of heavy quarks in the Quark Gluon Plasma (QGP). The perturbative calculations assume a trivial Polyakov loop, i.e., a fully deconfined QGP. However, RHIC and LHC probe the temperature windows where the Polyakov loop is significantly below unity, a regime termed the semi-QGP. To address this, we use the Holonomous Hard Thermal Loop (HHTL) framework, including the two-dimensional adjoint ghost fields. We present the theoretical framework and anticipated consequences of non-trivial holonomy for heavy-quark transport in the semi-QGP regime.
