*_Cake Seminar:_ *Monday, June 23, 2025 *at 1pm EDT*

*_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.
