This summer school will take place from June 9th to June 15th at the IJCLab in Orsay, close to the city of Paris (France). The school welcomes all PhD students and young postdocs in the fields of QCD, hadron and/or heavy-ion physics, both experimentalists and theorists. The scientific program of this school will provide the participants with the tools to navigate from the multidimensional structure of the nucleon (quantum chromodynamics, modifications in nuclei and parton saturation) to the properties and influence of the hot and dense QCD medium created in heavy-ion collisions (HIC). The formation of the quark-gluon plasma (QGP), its thermodynamic properties and the phase transition to hadronic matter will be discussed. The origin and observation of collective effects will also be discussed. Attention will be paid to the interplay between theory, phenomenology and experiment, and interdisciplinary links to nuclear structure physics. 

Internationally recognized researchers will give introductory lectures on hydrodynamics, nucleon and nuclear structure, probes of the QGP such as jets and heavy flavors both from theory and experiment, the simulation of HIC via event generators, the modification of hadrons in the medium and the initial state of a HIC.

The deadline for application is April 30th 2024.

One of our researchers (Carlota Andres) was invited to deliver lectures on jet quenching.

Energy-energy correlators (EECs) are powerful tools for collider QCD. They simultaneously enable precision measurements of complex collider phenomena whilst retaining strong links with highly developed techniques from conformal field theory and light-ray operator product expansions. The last decade has seen substantial growth in the field of EECs and the deep connections among conformal theories, jet substructure, heavy-ion physics and analytic QCD have just started to be explored. The goal of this workshop is to enable researchers across these different fields to meet and elaborate concrete strategies to fully exploit the potential of the EEC framework for collider phenomenology.

Some keys areas of focus include:

• Identifying new/unique phenomenological applications
• Developing techniques for computations of energy correlators in QCD
• Extending the links between EECs in conformal theories and EECs in QCD.
• Finding synergy between jet physics and heavy-ion physics within the EEC framework.
• Identifying how recent EEC developments can feedback into broader collider phenomenology and Monte Carlo generators.

The workshop will take place in Mainz (Germany), at the Mainz Institute for Theoretical Physics (MITP), between the 8th and the 19th of July, 2024. Applications will be open until the 11th of March.

The QCD Master Class 2024 will take place on June 23-July 6, 2024 in Saint-Jacut-de-la-Mer, a small village in Brittany (west of France) close to the city of Saint-Malo and the world famous Mont Saint-Michel. Five lectures in QCD, of approximately 10 hours each, will be given to 35 young researchers and faculty staff members. The lectures will cover three different topics each week, from Monday to Friday. The week-end in between the two weeks is left free (a visit to the Mont Saint-Michel will be scheduled).

Interested candidates should apply via the pre-registration form given here. Deadline for application is fixed to March 15, 2024. The candidates are expected to apply for the complete duration of the school, with preferably arrival on June 23 (afternoon) and departure on July 6 (morning). The selected 35 participants will be contacted in order to process with the payment of the fee to confirm final registration.

The registration fee is fixed to 850 euros and includes the full board accommodation from June 23 (evening) to July 6 (morning) as well as a round-trip bus ticket from Saint-Jacut to Mont Saint-Michel.

The mini-school on Particle and Astroparticle Physics, organized jointly by CFTP (Centro de Física Teorica de Particulas) and LIP (Laboratório de Instrumentação e Física Experimental de Partículas), provides undergraduate students with an overview of the field, covering both theoretical and experimental aspects.

The school is primarily aimed at third-year undergraduate physics students and will be held fully in in-person mode in Oeiras (Lisbon, Portugal), from the 5th to the 6th of February, 2024.

In the first day there will be introductory lectures on different topics. The second day will consist of hands-on tutorials (morning) and a session in which research opportunities will be presented to the participants by CFTP and LIP researchers (afternoon). MSc and PhD students from both research centres will present posters on their current research work. This will be an oportunity for the undergraduate students to exchange views with more advanced colleagues.

The deadline for (regular) registration is January 25, 2024. The deadline for registration requesting a grant is January 15, 2024.

Several of our members will participate in this school: Liliana Apolinario and Dario Vaccaro will present a hands-on tutorial on QCD jets, Grigorios Chachamis will deliver a lecture on phenomenology, and Pablo Guerrero will discuss research opportunities within the Pheno group.

An illuminating exploration into QCD theory, phenomenology, and experiments amidst the vibrant Nordic summer nights. This comprehensive two-week program will take place in Saariselkä (Finland) from the 24th of June to the 6th of July.

The detailed program of the meeting will be established according to the latest experimental and theoretical results at the time of the meeting. Participants who wish to present new results are requested to send an abstract of their proposed presentation to one member of the program committee  as soon as possible. Due to limitation of time, only a restricted number of talks can be accepted.

Both calls for registration and abstracts are open. Registration deadline: January 31, 2024. Abstract submission deadline: January 14, 2024.

This workshop aims to bring together several communities studying the dynamics of jets in Heavy Ion Collision experiments, the response of the matter to these probes, and the matter evolution itself. These communities study different but highly entangled subjects and would benefit from the combined developments and new opportunities to utilize the available tomographic tools jointly. The main goals of the workshop are to review and analyze the recent experimental and theoretical results, discuss the short term needs of each sub-field to be prioritized in the near future, and facilitate the cross-talk between them.

The main questions to be addressed in this workshop are the following:

• Could we utilize the existing theories of probe-matter interactions to access the real-time matter evolution and its differential properties?
• Can we provide a self-consistent description for the hard probes in QCD matter produced in HIC during all the stages of its evolution?
• Which novel measurements would be needed to extract the information about the evolution of the underlying nuclear matter?
• What is the current status of the tomographic toolkit for different hard probes on the experimental side?
• Can the new developments in jet quenching and initial stages physics help understand the evolution of jets in smaller systems?

The workshop will take place in Trento (Italy) between the 12th and the 16th of February, 2024. Applications will be open until the 19th of January.

The Pheno group is involved in the organization of this event. In addition, several of our members (André Cordeiro, Guilherme Milhano, João Gonçalves, João Silva, Nuno Olavo and Pablo Guerrero) will attend and deliver talks.

Marco Leitão, MEFT student at IST, is our most recent MSc. His thesis, QGP effects on Energy Correlators inside jets’ was defended on 6 December. Marco’s work, supervised by Guilherme Milhano, examined the unique potential of energy correlators to isolate the effect of the QGP response to the passage of a jet and to determine the critical temperature for existence of QGP. The jury members were Mário Pimenta, Liliana Apolinário, and Guilherme Milhano.

Congratulations to Master Marco!
