Unbiased Data-Driven Determination of the Nuclear Dipole Amplitude in the Color Glass Condensate

This paper presents a physics-informed neural-network framework that embeds the Balitsky-Kovchegov evolution equation to unbiasedly extract the nuclear dipole amplitude for 208^{208}Pb directly from experimental data, revealing a saturation scale consistent with geometric scaling and successfully predicting transverse-momentum ratios in various collision systems without system-dependent parameters.

Laplace-Space Analysis of xF3xF_3 Including Nuclear Effects and Gegenbauer-Polynomial Parton Distributions

This paper presents a next-to-leading and next-to-next-to-leading order QCD analysis of the non-singlet structure function xF3xF_3 using a Gegenbauer-polynomial parameterization for parton distributions and Laplace-space DGLAP evolution to systematically incorporate nuclear effects, thereby improving the extraction of valence quark distributions and the consistency of sum rules with data from CCFR, NuTeV, and CHORUS experiments.

Charge-exchange reactions with pion and kaon beams in the NA64h experiment at CERN

This paper presents a new approach for the NA64h experiment at CERN to search for dark sector particles via invisible decays and oscillations of neutral mesons produced in charge-exchange reactions with pion and kaon beams, focusing on the accurate evaluation of the necessary cross sections to estimate the experiment's sensitivity.

GGI Lectures on Large-Scale Structure Perturbation Theory (Effective Field Theory)

This paper provides a pedagogical introduction to non-linear perturbation theory for cosmological large-scale structure, specifically developing the Effective Field Theory framework from scratch to model galaxy clustering, address the limitations of Standard Perturbation Theory, and incorporate galaxy bias and redshift-space distortions for undergraduate and beginning graduate students.

Estimating amplitude of matter density fluctuations in solar and supernova models using neutrino flavor evolution

This paper demonstrates that statistical data assimilation can effectively estimate the amplitude of matter density fluctuations in solar and core-collapse supernova models by analyzing neutrino flavor evolution, with the method showing particular reliability in solar scenarios.

Schwinger Current in de Sitter Space

This paper demonstrates that by imposing a physically consistent renormalization condition and accounting for the required tachyonic photon mass in de Sitter space, the Schwinger current for charged fermions and scalars is finite and positive even in the massless limit, thereby resolving previous issues of negative infrared divergence and offering new insights into magnetogenesis and inflationary dark matter production.
