Session 2WLA: Probing the Quark-gluon Plasma with Jets and Heavy-flavor Particles I

Open and Hidden Heavy Flavor Production in p+p, p+A and A+A Collisions

We present a brief overview of recent open heavy and quarkonium theory advances in proton-proton (p+p), proton-nucleus (p+A) and nucleus-nucleus (A+A) collisions.  The talk will focus primarily on work done for collisions at the LHC.   

Probing the Quark-gluon Plasma with jet substructure techniques

In heavy ion collisions a dense state of matter called the quark-gluon plasma (QGP) is formed. High momentum partons that are also produced in these collisions interact with this plasma. The outgoing spray of particles originating from the high momentum partons, jets, can be studied in the experiment to constrain the properties of the QGP. Measurements in heavy ion collisions are compared to proton-proton collisions to quantify how large the modification due to the presence of the QGP is. In recent years jet substructure measurements have proven particularly powerful to disentangle the various effects occurring during the full evolution of the parton shower. Jet substructure measurements are compared to model calculations to further understand the mechanism of parton-medium interactions and the properties of the QGP.
