An Overview of Scale Invariance in Proton Structure With Holographic Insights

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The concept of self‐similarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering (DIS).

Extraction of Effective Parameters From Transverse Momentum Spectra of Heavy Quarkonia in Proton–Proton Collisions at the LHC

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The effective string tension (κ) in the Schwinger mechanism and the effective temperature (T) in Bose–Einstein statistics are extracted from the transverse momentum (pT) spectra of heavy quarkonia produced in proton‐proton (p + p) collisions at the Large Hadron Collider (LHC).

Superselection rules, quantum error correction, and quantum chromodynamics

Journal of High Energy Physics
We investigate the relationship between superselection rules and quantum error correcting codes. We demonstrate that the existence of a superselection rule implies the Knill-Laflamme condition in quantum error correction.

Mass Spectra, Radii, and Decay Widths of Toponium

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
In this work, the radial Schrodinger equation with a nonrelativistic quark potential model (NRQPM) is solved numerically by employing the shooting method. Calculated numerical wave functions (or solutions) are used to compute the masses, root mean square (RMS) radii, E1, M1 radiative transition widths, annihilation decay widths, and branching ratios of

Discoveries in ultra-peripheral collisions: Past, present, future [PDF]

EPJ Web of Conferences
Ultra-relativistic heavy-ion collisions produce extremely strong electromagnetic field which provide a uniquely intense and energetic source of photons. The photons manifest from such ultra-Lorentz contracted electromagnetic fields have, in recent years,

Polarization rotation of chiral fermions in vortical fluid

Physics Letters B, 2021
The rotation of polarization occurs for light interacting with chiral materials. It requires the light states with opposite chiralities interact differently with the materials.

Free energy expansions of a conditional GinUE and large deviations of the smallest eigenvalue of the LUE

Communications on Pure and Applied Mathematics, Volume 78, Issue 12, Page 2247-2304, December 2025.
Abstract We consider a planar Coulomb gas ensemble of size N$N$ with the inverse temperature β=2$\beta =2$ and external potential Q(z)=|z|2−2clog|z−a|$Q(z)=|z|^2-2c \log |z-a|$, where c>0$c>0$ and a∈C$a \in \mathbb {C}$. Equivalently, this model can be realised as N$N$ eigenvalues of the complex Ginibre matrix of size (c+1)N×(c+1)N$(c+1) N \times (c+1)

Active Learning in Physics: From 101, to Progress, and Perspective

Advanced Quantum Technologies, Volume 8, Issue 12, December 2025.
In this review, the concept of active learning is introduced to the physicists at the level of beginner without requirement on background in machine learning. It includes most of the latest applications of active learning in branches of physics, covering but not being limited to quantum information, high energy physics, and condensed matter physics. It

Round table: What can we learn about confinement and anoma-lous effects in QCD using analog systems?

EPJ Web of Conferences, 2017
We discuss an number of examples for recent connections between emergent phenomena in many-body systems in atomic and condensed matter physics, and confinement and other non-perturbative phenomena in quantum chromodynamics.
