Abstract:
Measuring the temperature of the quark-gluon plasma is a central task that calls for close collaboration between experiment and theory. Understanding e.g. the dynamics of hard probes as they traverse the bulk, promises such insight into the surrounding thermal medium. Here we report on recent progress in the description of the in-medium real-time evolution of Bottomonium states, based on a complex valued effective field theory potential, extracted from first principles lattice QCD. The concept of open-quantum systems, well known in condensed matter theory, allows us to intuitively understand the role of the imaginary part of this potential as it provides a clear connection to the thermal fluctuations of the surrounding heat bath.
