Ivan Vitev (Los Alamos),``<span>Effective field theories in reactions with nuclei: from jets to quarkonia''<br>
</span>
<div><u>Abstract</u>:<br>
</div>
<div>In this talk I will show how modern effective theories of QCD can be generalized to include parton interactions in nuclear matter. This allows us to develop a first principles framework for precise theoretical calculations in reactions with nuclei, such
as e+A, p+A, and A+A in current and future collider facilities. As a first example I will discuss Soft Collinear Effective Theory (SCET) and the derivation of a full set of in-medium branching processes to any order in the opacity of nuclear matter. Recent
application to b-jet production and jet charge modification in heavy ion collisions will be shown. As a second example I will discuss Non-relativistic Quantum Chromodynamics (NRQCD). NRQCD with Glauber gluons can provide for the first time a universal microscopic
description of the interaction of heavy quarkonia with a strongly interacting medium, consistently applicable to a range of phases, such as cold nuclear matter, dense hadron gas, and quark-gluon plasma. Its connection to quarkonium phenomenology in heavy ion
reactions will be elucidated.</div>

<div><u>Abstract:</u><br>
</div>
<div>In this talk I report recent results on the in-medium properties of heavy quarkonium from a combination of lattice QCD and the effective field theories NRQCD as well as pNRQCD. This includes the first robust determination of in-medium mass shifts consistent
among the different EFT approaches [1], as well as the in-medium potential on realistic lattices [2]. In addition, our latest results on the open-quantum-systems approach to heavy-quarkonium real-time dynamics will presented [3].<br>
