Analyse de systèmes quantiques relativistes
09 jan 2023 - 13 jan 2023 • CIRM (Marseille Luminy), France
Organisateur:
CIRM – Centre International de Rencontres Mathématiques
Résumé:
Relativistic Quantum Mechanics is central in Physics and Mathematical Physics. It plays a very important role in the analysis of many relevant topics in that field. The basic operator for relativistic models is the Dirac operator. Contrary to the case of the non-relativistic Schrödinger operator, the Dirac operator is not semi-bounded, its spectrum being real and unbounded in both directions, for positive and negative values having a gap (−m, m), m the mass of the particle, in the middle of the essential spectrum. This property has many consequences, both for the physical interpretation of the solutions of the models based on the Dirac operator as for the much more difficult mathematical analysis of those models. These difficulties arise already at the level of one-particle systems. For N-particle systems, the difficulties arising from the total unboundedness of the operator together with the usual difficulties for N-particle systems in Quantum Mechanics are very stimulating mathematically, since they are the source of a large number of very interesting and difficult problems that are far from being understood at the moment. Various groups of mathematicians and mathematical physicists have specialized on these topics in the past two or three decades and have produced already a good amount of important results. But much remains to be understood and proved. The aim of this workshop is to stimulate the interaction of researchers in all those groups, researchers who have different approaches, points of view and methodologies. Also many of them have so far specialized on a part of the theory, and open discussions about the models, the difficulties to analyze them, the existing methods, the new perspectives to tackle more difficult problems out of reach at the moment, among all of them should be a great opportunity for making progress and opening new perspectives for the future.

QCD evolution Workshop 2023
22 mai 2023 - 26 mai 2023 • IJCLab, Orsay, France
Organisateur:
Université Paris-Saclay in Orsay
Résumé:
A main objective of QCD Evolution Workshop is to provide a forum to discuss the recent scientific accomplishments in areas such as Transverse Momentum Distributions (TMDs), Generalised Parton Distributions (GPDs), and small-x physics, together with advances in perturbative and non-perturbative techniques within QCD, such as lattice QCD and effective field theory techniques. In doing so this workshop also aims to support and guide the physics programs at facilities such as Jefferson Lab, the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab, Fermi National Accelerator Laboratory, and the Large Hadron Collider (LHC) complex at CERN. The workshop is also central to the building of the next-generation nuclear physics facility in the US, the Electron Ion Collider (EIC).

FPCP — 21st Conference on Flavor Physics and CP Violation
29 mai 2023 - 02 jui 2023 • Lyon, France
Organisateur:
IP2I - University of Lyon
Résumé:
The Flavor Physics and CP Violation (FPCP) conferences are intended for the exchange of new ideas, for presentation of the latest experimental and theoretical results in the areas included in the conference title, and for discussions about future projects in the field. The conference is open to all experimental and theoretical physicists interested in the field. This conference series results from the merging of the Heavy Flavor Physics Conference and the International Conference on B Physics and CP Violation in 2002.
