Azimuthal Asymmetry in Quarkonium Production in Heavy-Ion Collisions

Published:Dec 29, 2025 08:50
1 min read
ArXiv

Analysis

This paper explores the production of $J/ψ$ mesons in ultraperipheral heavy-ion collisions at the LHC, focusing on azimuthal asymmetries arising from the polarization of photons involved in the collisions. It's significant because it provides a new way to test the understanding of quarkonium production mechanisms and probe the structure of photons in extreme relativistic conditions. The study uses a combination of theoretical frameworks (NRQCD and TMD photon distributions) to predict observable effects, offering a potential experimental validation of these models.
Reference

“The paper predicts sizable $\cos(2φ)$ and $\cos(4φ)$ azimuthal asymmetries arising from the interference of linearly polarized photon states.”

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 $W$.”
