LIP at the Quark Matter 2025
"The XXXI edition of the International Quark Matter Conference took place in Germany, bringing together experts from all over the world, including members of LIP's Phenomenology group"
Last week, the XXXI edition of the Quark Matter International Conference took place in Frankfurt, Germany, bringing together global experts to discuss breakthroughs in ultra-relativistic nucleus-nucleus collisions.
Attendees were eagerly anticipating the latest experimental results from the LHC heavy-ion programme, which now boasts unprecedented statistics from both its second and third runs. These results critically examine the transport properties of the Quark-Gluon Plasma, providing novel insights into its thermalisation characteristics and revealing the medium’s response to highly energetic probes. Additionally, the first measurements of coincident ultra-peripheral collision events have enabled precise analyses of the structure of incoming nuclei.
The LIP Phenomenology group continues its active participation in this significant event. The previous week, a dedicated satellite workshop at CERN titled “High Energy Probes of the Initial Stages” set the stage for pivotal discussions. The group leader, Liliana Apolinário, opened the workshop with her talk on “Jets as Probes of the Initial Stages”. Additionally, Andrey Sadofyev delivered a well-received colloquium at CERN on “High-energy probes of the initial stages in heavy-ion collisions”, and João M. Silva presented his latest research on “Exploring Anisotropic QCD Matter with Jets”. Liliana was also invited to convene the final discussion session on Experimental and Phenomenological Opportunities.
At the main Quark Matter 2025, five LIP PhD students presented their most recent research contributions. André Cordeiro delivered a talk on “Gluon Emission by a Quark-Antiquark Antenna with Realistic Parton-Medium Interactions”, while João M. Silva presented his work on “Energy Correlators for Gluon Splitting to Heavy Quarks”.
In the poster sessions, João A. Gonçalves showcased his study titled “Apples to Apples in Jet Quenching: Underlying Event Considerations for Phenomenological Jet Studies in Heavy-Ion Collisions”. Marco Leitão discussed his progress through a poster on “Advancing Our Understanding of the In-Medium q → qg Splitting Function”, and Nuno Olavo Madureira presented his poster on “Improving Charge Ratio's Sensitivity to Hadronization via Jet Substructure”. Liliana Apolinário also presented a new proposal for “Uncovering Energy Loss in Small Systems via the Tau-Algorithm” in the poster sessions.
