A crazy picture of the #occultation of the #Pleiades by the #Moon right now ... shot with a handheld camera through a window and a hole in the clouds from Bochum, Germany.

But hey, I kinda got it. ;-)

Statistical conservation laws for scalar model problems: Hierarchical evolution equations
The probability density functions (PDFs) for the solution of the incompressible Navier-Stokes equation can be represented by a hierarchy of linear equations. This article develops new hierarchical evolution equations for PDFs of a scalar conservation law with random initial data as a model problem. Two frameworks are developed, including multi-point PDFs and single-point higher-order derivative PDFs. These hierarchies capture statistical correlations and guide closure strategies.

This fascinates me. Probably part of the same brain structures that inform my love of history, and my love of figuring out how to get certain old guitar tones

Impact of new measurements of light quarks at hadron colliders
Recently a series of new measurements with both the neutral and charge current Drell--Yan processes have been performed at hadron colliders, showing deviations from the predictions of the current parton distribution functions (PDFs). In this article, the impact of these new measurements is studied by using their results to update the PDFs. Although these new measurements correspond to different boson propagators and colliding energies, they are found to have a similar impact to the light quark …

Towards next-gen parton distribution and fragmentation functions
The interest into parton distribution functions (PDFs) and fragmentation functions (FFs) in current high energy physics research is twofold. On the one hand, they are fundamental objects to conduct precision phenomenology studies, e.g. at the Large Hadron Collider (LHC), to determine the Standard Model parameters and search for new physics. On the other hand, they are also a means to understand the inner structure and dynamics of hadrons, e.g. in regards to the proton spin decomposition at the …

Determination of the pion generalized parton distributions at zero skewness
We perform a global QCD analysis of the pion electromagnetic form factor (FF) data from pion electroproduction and elastic pion scattering to extract the valence pion generalized parton distributions (GPDs) at zero skewness. The analysis uses three different sets of pion parton distribution functions (PDFs), namely xFitter, JAM21, and MAP23, to construct the GPD ansatz. Through a $χ^2$ minimization and a careful parametrization scan, we determine the profile function parameters and find that o…
