Séminaire de Carlota Andres-Casas, 21/11/2024, 11h, au CPHT, Salle JEAN LASCOUX

Probing the Quark-Gluon Plasma with Energy Correlators

Recent advances in conformal field theory have led to the reformulation of collider jet substructure as the study of correlation functions of the energy flux, known as energy correlators, and their associated light-ray operator product expansion (OPE). Multi-point energy correlators have been measured in proton-proton collisions at the Large Hadron Collider (LHC), offering experimental validation of the light-ray OPE. In this talk, I will highlight the advantages of using energy correlators to probe the quark-gluon plasma produced in heavy-ion collisions, for which the first energy correlator measurement has recently been unveiled. Building on the unique properties of energy correlators, I will introduce a novel observable that stands as the first heavy-ion jet substructure observable where energy loss (or selection bias) is not the leading effect.

 

Mathematical physics seminar, on Monday november 18, 2024, 2 pm, in the lecture room Louis Michel at CPHT

Jürg Fröhlich (ETH Zürich)

"The stochastic evolution of isolated systems in quantum mechanics"

Abstract: In this talk I describe a Law of Dynamics for non-relativistic Quantum Mechanics (QM). The time evolution of physical systems consisting of charged matter interacting with the quantized electromagnetic field, e.g., electrons in the shell of an atom coupled to the radiation field, is non-linear, dissipative and stochastic, featuring isolated random events sometimes called “quantum jumps”. We discuss the equations describing it ! They involve a new type of stochastic process, dubbed “quantum Poisson jump process." An application to the phenomenon of fluorescence will be sketch

 

The CPHT Young Researchers Seminar will be held on Thursday the 14th of November at 14h00 in room Jean Lascoux.
