Month: June 2024

Last week marked a significant achievement for Guilherme Calé, a student at the Faculty of Sciences of the University of Lisbon and member of the Pheno group at LIP. Guilherme successfully defended his master thesis, titled “Particle-Particle and Jet-Jet Angular Correlations at the Parton Level”.

Guilherme’s research, guided by supervisors Grigorios Chachamis and João Pires, was an in-depth exploration of partonic correlations and their manifestation at parton jet level. The study was based on simulations of high-energy collisions for multiple systems (proton-proton, proton-nucleus and nucleus-nucleus), whose angular correlations were analyzed and compared for two Monte Carlo codes (Pythia and BFKLex). In all of the examined cases, no connection was found between the high-energy QCD dynamics considered (i.e. BFKL evolution) and the enigmatic near-side, long-range correlations observed in data.

The jury for the thesis defense comprised Margarida Cruz (president), Liliana Apolinário (main arguer), and Grigorios Chachamis (as the supervisor representative).

Congratulations to Guilherme!

ISMD 2024 will be held from September 23 to 27, 2024, in Malargüe, Argentina. This event will bring together physicists from across particle, nuclear, and astrophysics for talks and discussions focused on all aspects and consequences of the strong nuclear force, as well as its complex final states. In order to encourage cross-talk between areas, all presentations at ISMD will be programmed in plenary sessions, organized into the following scientific tracks:

    •  Cosmic ray and astroparticle physics
    •  Multiparticle correlations and fluctuations
    •  Forward physics: Diffraction, Odderon and Pomeron
    •  Hadronic final states in high pT interactions
    •  Collectivity in high energy collisions: jets, flows, and other mechanisms
    •  Proton structure, small-x and large-x physics
    •  Hadronic issues in heavy-flavour physics
    •  Beyond Standard Model Physics and new developments in HEP

Registration deadline: Aug 30th, 2024. Abstract submission deadline: July 15th, 2024.

A significant volume of experimental data on jet observables has been accumulated through extensive analyses of heavy-ion collision experiments in the last decades. On the theoretical front, there have been comprehensive discussions regarding the jet structures and QGP medium effects on them, involving new proposals for additional possible observables guided by these experimental findings. Now a key challenge is to establish a coherent understanding of various observables across different momentum ranges and collision energies and systems, which is essential for deepening our insights into the dynamical jet-QGP interactions.

This workshop (satellite workshop of Hard Probes 2024) will take place at the University of Tokyo, from the 28th to the 29th of September 2024. Its main goal is to capturing a full picture of jet phenomena and related observables from theoretical and experimental perspectives. It is intended to identify the most pressing issues broadly significant in dynamical jet-induced phenomena at this time and to provide a pathway to understanding core mechanisms, which will make the next step towards comprehending the jet properties and the QGP medium.
