Speaker: Kawtar El Bouzaidi (Mohammed V U. Rabat)

Title: Exploring the Quantum Nature of Neutrinos Oscillations.

Abstract: Neutrino oscillations, a macroscopic quantum phenomenon, are traditionally viewed through the lens of flavor conversion probabilities. However, this perspective often understates the rich tapestry of underlying quantum correlations, such as coherence and entanglement, inherent in the neutrino state. This work thoroughly investigates these quantum correlations within both idealized plane-wave and realistic wave-packet descriptions of neutrino oscillations. For the mixed states that emerge from wave-packet propagation, our analysis reveals a complex and dynamic interplay between various quantum information measures, including predictability, local coherence, mutual information, and quantum discord. Using experimental parameters from Daya Bay, KamLAND, and MINOS, we demonstrate a significant finding: these crucial quantum correlations can persist even when the characteristic flavor oscillations are washed out at long propagation distances. These results offer a deeper understanding of neutrino quantum dynamics, highlighting neutrinos not just as fundamental particles but as unique systems for exploring and potentially leveraging quantum information principles.

Title: The polarized photon distribution function.

Abstract: The parton distribution functions (PDFs) are a fundamental component of hard scattering processes. At leading order, they represent the probability of finding a parton with a momentum fraction x in a hadron target. With the increase in the accuracy of experimental measurements over the last few decades, it has become necessary to enhance the precision of theoretical calculations. To achieve this goal, precise fits of PDFs are indispensable.
In this presentation, I will discuss the LuxQED method for computing the polarized photon PDF. This method allows us to express the photon PDF in terms of the structure functions g1 and g2. The difficulty arises from the necessity of knowing the structure functions across the entire parameter space. I will discuss some models and assumptions available for modeling g1 and g2 in the different regions of the parameter space.
