Description
Heavy-ion collisions are an essential tool to better understand the deconfined phase of Quark-Gluon Plasma . Probes such as heavy particles are used indirectly to study its properties. In describing the propagation of heavy particles in a medium, non-relativistic effective field theories are employed. In doing so, correlators of chromoelectric fields appear and are important in the evolution of the probes inside the plasma; for example correlators in the adjoint representation are associated with heavy quarkonium physics. Moreover, such correlators are vital in determining some of the transport coefficients that characterise the propagation of heavy probes.
I will show results from a perturbative evaluation of chromoelectric correlators in adjoint representation at NLO in Imaginary-Time (Euclidean) QCD at finite temperatures. Euclidean space is extremely useful as it makes direct contact with Lattice QCD. We make use of recent advancements in thermal integration by parts methods to tackle the loop integrals present. This results in analytically more tractable integrals, allows automation and provides a clear path for potential extension to higher orders in perturbation theory. Finally, I will also discuss the steps needed to extract transport coefficients from these correlators and discuss their physical meaning.
