Pion Structure in Dense Nuclear Matter

Published:Dec 31, 2025 15:25
1 min read
ArXiv

Analysis

This paper investigates how the internal structure of a pion (a subatomic particle) changes when it's inside a dense environment of other particles (like in a nucleus). It uses a theoretical model (Nambu--Jona-Lasinio) to calculate these changes, focusing on properties like the pion's electromagnetic form factor and how its quarks are distributed. Understanding these changes is important for understanding how matter behaves under extreme conditions, such as those found in neutron stars or heavy-ion collisions. The paper compares its results with experimental data and other theoretical calculations to validate its approach.
Reference

“The paper focuses on the in-medium electromagnetic form factor, distribution amplitude, and the parton distribution function of the pion.”

Dilepton Emission as a Probe of QCD Critical Point

Published:Dec 31, 2025 05:41
1 min read
ArXiv

Analysis

This paper proposes using dilepton emission rates (DER) as a novel probe to identify the QCD critical point in heavy-ion collisions. The authors utilize an extended Polyakov-quark-meson model to simulate dilepton production and chiral transition. The study suggests that DER fluctuations are more sensitive to the critical point's location compared to baryon number fluctuations, making it a potentially valuable experimental observable. The paper also acknowledges the current limitations in experimental data and proposes a method to analyze the baseline-subtracted DER.
Reference

“The DER fluctuations are found to be more drastic in the critical region and more sensitive to the relative location of the critical point.”

Jet Quenching in Anisotropic Holographic QCD

Published:Dec 30, 2025 13:05
1 min read
ArXiv

Analysis

This paper investigates jet quenching in an anisotropic quark-gluon plasma using gauge-gravity duality. It explores the behavior of the jet quenching parameter under different orientations, particularly focusing on its response to phase transitions and critical regions within the plasma. The study utilizes a holographic model based on an Einstein-dilaton-three-Maxwell action, considering various physical conditions like temperature, chemical potential, magnetic field, and spatial anisotropy. The significance lies in understanding how the properties of the quark-gluon plasma, especially its phase transitions, affect the suppression of jets, which is crucial for understanding heavy-ion collision experiments.
Reference

“Discontinuities of the jet quenching parameter occur at a first-order phase transition, and their magnitude depends on the orientation.”

Spin Fluctuations as a Probe of Nuclear Clustering

Published:Dec 30, 2025 08:41
1 min read
ArXiv

Analysis

This paper investigates how the alpha-cluster structure of light nuclei like Oxygen-16 and Neon-20 affects the initial spin fluctuations in high-energy collisions. The authors use theoretical models (NLEFT and alpha-cluster models) to predict observable differences in spin fluctuations compared to a standard model. This could provide a new way to study the internal structure of these nuclei by analyzing the final-state Lambda-hyperon spin correlations.
Reference

“The strong short-range spin--isospin correlations characteristic of $α$ clusters lead to a significant suppression of spin fluctuations compared to a spherical Woods--Saxon baseline with uncorrelated spins.”

Temperature Fluctuations in Hot QCD Matter

Published:Dec 30, 2025 01:32
1 min read
ArXiv

Analysis

This paper investigates temperature fluctuations in hot QCD matter using a specific model (PNJL). The key finding is that high-order cumulant ratios show non-monotonic behavior across the chiral phase transition, with distinct structures potentially linked to the deconfinement phase transition. The results are relevant for heavy-ion collision experiments.
Reference

“The high-order cumulant ratios $R_{n2}$ ($n>2$) exhibit non-monotonic variations across the chiral phase transition... These structures gradually weaken and eventually vanish at high chemical potential as they compete with the sharpening of the chiral phase transition.”

Hadronic Matter's Impact on Jet Energy Loss

Published:Dec 29, 2025 18:51
1 min read
ArXiv

Analysis

This paper investigates how the properties of hadronic matter influence the energy loss of energetic partons (quarks and gluons) as they traverse the hot, dense medium created in heavy-ion collisions. The authors introduce a modification to the dispersion relations of partons, effectively accounting for the interactions with the medium's constituents. This allows them to model jet modification, including the nuclear modification factor and elliptic flow, across different collision energies and centralities, extending the applicability of jet energy loss calculations into the hadronic phase.

“The paper introduces a multiplicative $(1 + a/T)$ correction to the dispersion relation of quarks and gluons.”

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.”

ArXiv

Analysis

This paper investigates how jets, produced in heavy-ion collisions, are affected by the evolving quark-gluon plasma (QGP) during the initial, non-equilibrium stages. It focuses on the jet quenching parameter and elastic collision kernel, crucial for understanding jet-medium interactions. The study improves QCD kinetic theory simulations by incorporating more realistic medium effects and analyzes gluon splitting rates beyond isotropic approximations. The identification of a novel weak-coupling attractor further enhances the modeling of the QGP's evolution and equilibration.
