ANN for Diffractive J/ψ Production at HERA

Published:Dec 25, 2025 14:56
1 min read
ArXiv

Analysis

This paper uses an Artificial Neural Network (ANN) to analyze data from the HERA experiment on coherent diffractive J/ψ production. The authors aim to provide a model-independent analysis, overcoming limitations of traditional model-dependent approaches. They predict differential cross-sections and extend the model to include LHC data, extracting the exponential slope 'b' and analyzing its dependence on kinematic variables. This is significant because it offers a new, potentially more accurate, way to analyze high-energy physics data and extract physical parameters.
Reference

“The authors find that the exponential slope 'b' strongly depends on $Q^2$ and $W$.”

Elemental Spectral Index Variations in Cosmic Rays

Published:Dec 25, 2025 13:38
1 min read
ArXiv

Analysis

This paper investigates discrepancies between theoretical predictions and observed cosmic ray energy spectra. It focuses on the spectral indices of different elements, finding variations that contradict the standard shock acceleration model. The study uses observational data from AMS-02 and DAMPE, and proposes a Spatially Dependent Propagation (SDP) model to explain the observed correlations between spectral indices and atomic/mass numbers. The paper highlights the need for further observations and theoretical models to fully understand these variations.
Reference

“Spectral indices show significant positive correlations with both atomic number Z and mass number A, likely due to A or Z-dependent fragmentation cross-sections.”
