Hot QCD in heavy-ion collisions at the LHC

Sala 1.4.14, Ciências ULisboa

Por Carlota Andrés (LIP).

The Quark-Gluon Plasma (QGP) produced in high-energy collisions of heavy nuclei at the Large Hadron Collider (LHC) is an exotic state of matter made of deconfined quarks and gluons believed to have existed microseconds after the Big Bang. In this seminar, I will review our current understanding of this hot Quantum Chromodynamics (QCD) matter, including its collective behavior at "large" length scales and the study of its shorter length scales through jets. A particular emphasis will be placed on discussing the big open questions regarding hot QCD matter to be addressed within the next decade of heavy-ion collisions at the LHC. Finally, I will explore the connections between the QGP produced at the LHC and new astrophysics measurements related to neutron stars.

Short Bio: C. Andrés’ work is focused on Quantum Chromodynamics (QCD), the underlying theory describing the strong interaction. She is especially interested in QCD under extreme conditions as those attained in heavy-ion collisions at the LHC. She completed her PhD in theoretical physics in 2017 at the University of Santiago de Compostela. Then, she moved to Jefferson Lab for her first postdoctoral appointment (2018-2020). During the pandemics, she worked remotely as a postdoc for LIP (Lisbon) (9-2020/8-2021) and in 9/2021 she moved to the Paris area to work as a Marie Curie Individual fellow at the Center of Theoretical Physics in Ecole Polytechnique. Since last December she has been back at LIP, working with the Phenomenology group, this time in person.
