Effective Field Theory and Lattice QCD approaches for hard probes in QCD matter

Understand

Hard Probes are an essential tool to discover the properties of the quark-gluon plasma created in heavy-ion collisions.

• The study of hard probes always involves taking into account very different energy scales, and this is precisely the situation in which Effective Fields Theories (EFTs) are useful.
• EFTs can be used to separate the short-distance and perturbative physics from the long-distance and non-perturbative.
• This method combined with Lattice QCD evaluations of the long-distance effects can provide accurate and first principles results.
