Journée des Nouveaux Entrants du Pôle Théorie (JNE)

jeudi 2 févr. 2023, 14:00 → 19:00 Europe/Paris

Amphithéatre 1 (Bat. 210, Université Paris-Saclay)

The Journée des nouveaux entrants du Pôle Théorie" is the theory division freshman day. The goals of the event is twofold:

1. Welcome PhD students, Postdocs and new staff scientists by providing a friendly venue where we can first meet and present ourselves;
2. Provide all the relevant information to the newcomers in terms of administrative, IT and HR operations in CNRS and at the lab/IN2P3.

For the latter, we have identified a few points that will be discussed during this meeting:

1. HR process for i) hosting internship students, ii) visiting scholar, which will cover how to request ZRR access;
2. AGATE-tempo - CNRS applications for taking vacations;
3. (pour les étrangers) Accueil en France: maintenir son statut légal (VISA préfecture), assurances, mutuelle et impôts;
4. Business travel (with example of the IJCLab intranet request and CNRS simbad portail for booking tickets);
5. NSIP, Ositah;
6. Quesaco SSH/certificat RSA/computing stations/login node at IJCLab/gitlab;
7. CCIN2P3, Ruche and other local cluster facilities;
8. Good IT practice (backup, zimbra, phishing...);
9. Walk-through IJCLab intranet services;
10. Compiler/librairies at IJClab and shared storage services;
11. CNRS and IN2P3 clouds services.

11 Curing high-energy instability of quarkonium production cross sections with High-Energy Factorization

The problem of negative NLO cross sections of heavy quarkonium production at high collision energies is considered[1]. It arises due to unphysical behaviour of the high partonic energy asymptotics of NLO partonic coefficient function in collinear factorisation, which can be cured via matching of the NLO calculation with Leading-Logarithmic resummation of partonic center-of-mass energy logarithms. The latter resummation is done using the formalism of High Energy Factorisation.

13 SAN JOSE PEREZ Miguel Teseo

During this brief talk, I will outline my trajectory so far, from my hometown of Logroño, to my PhD in Mainz, and I might even take the chance to discuss my hobbies.
Focusing on the present, during my postdoc in Orsay I study charmonium states and their properties via Lattice QCD simulations. My work is divided in two projects, both with my supervisor in Orsay, Benoît Blossier. For the first one, we are interested in computing the decay width of the charmonium state $\psi(3770)$ employing an alternative technique to the mainstream Lüscher analysis. For the second, we work on the so-called pseudo-distribution amplitudes approach to study the structure of the $\eta_c$ and $J/\psi$ states.

20 Physique Nucléaire

We develop state-of-the-art theoretical methods in nuclear structure and reactions, nuclear astrophysics and dynamics. Our group specializes in many-body theories (from nuclear density functional to ab initio methods coupled to effective field theory) and related numerical and formal techniques. We are particularly fond of interdisciplinary connections and emerging technologies, e.g. ultra-cold gases of bosonic or fermionic atoms, machine learning technologies and quantum computing. At the same time, we work in close connection with IJClab experimentalists, particularly on the microscopic interpretation and prediction of nuclear physics data.
