<b><u>Abstract:</u></b> 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.</div>

<b><u>Abstract:</u></b> 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.<br>
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.</div>
