Landau-Khalatnikov-Fradkin Transformations in Reduced Quantum Electrodynamics: Perturbative and Nonperturbative Dynamics of the Fermion Propagator

This paper presents a comprehensive analysis of Landau-Khalatnikov-Fradkin transformations in reduced quantum electrodynamics to derive the fermion propagator in arbitrary covariant gauges, identifying $\xi=1/3$ as the optimal reference gauge for simplifying perturbative calculations and numerically confirming the gauge invariance of the chiral condensate and fermion pole mass.

Double Metric Learning for Building Directed Graphs with Chain Connections for the ATLAS ITk Detector

This paper proposes a "Double Metric Learning" approach that learns two distinct node representations to resolve conflicts in constructing directed graphs with chain connections for the ATLAS ITk detector, demonstrating improved performance in graph construction and edge direction prediction for high transverse momentum particles compared to simple metric learning.

Kapitza Dynamics as a New Stabilization Mechanism for Heavy Tetraquarks

This paper proposes a Kapitza-inspired stabilization mechanism, where rapid oscillations in heavy-quark interactions generate a repulsive $1/r^4$ term that prevents collapse and successfully predicts the masses and properties of various heavy tetraquarks, including $X(3872)$ , $T_{bb}$ , and fully heavy $bb\bar{b}\bar{b}$ states, within a unified diquark–antidiquark framework.

Reconciling TM $_2$ Mixing with LMA and Dark-LMA Data based on Minimal Corrections from Charged-Lepton Sector

This paper demonstrates that minimal corrections from the charged-lepton sector, parameterized by the Wolfenstein mixing angle $\lambda$ and phase $\delta$ , can successfully reconcile the TM $_2$ neutrino mixing framework with both standard and dark-LMA oscillation data while predicting sizeable CP violation and testable effective Majorana mass ranges for neutrinoless double beta decay.

Scattering and depletion in a flying focus from conformal transformations

This paper demonstrates that photon emission and scattering amplitudes in flying focus fields can be derived from plane wave results via conformal transformations and Gaussian averaging, effectively allowing strong-field QED calculations to include focusing effects without additional computational cost.

Radiative correction to the charge asymmetry in $e^{+}e^{-}\to\mu^{+}\mu^{-}$ process

This paper presents the calculation of next-to-next-to-leading order (NNLO) QED radiative corrections to the $C$ -odd part of the differential cross section for the $e^{+}e^{-}\to\mu^{+}\mu^{-}$ process, thereby completing the analytical determination of the full NNLO differential cross section when combined with the authors' previous work.

AI-Driven Discovery of Information-Efficient Collider Observables for Interference Measurements

This paper demonstrates that AI-driven symbolic evolution can discover compact, interpretable event-level observables for collider interference measurements that retain substantially more statistical information than standard angular baselines by leveraging matrix-element reweighting scores.

Unified study of scalar, vector and tensor two-meson form factors in $U(3)$ resonance chiral theory

This paper systematically calculates and unitarizes scalar, vector, and tensor two-meson form factors within $U(3)$ resonance chiral theory by combining one-loop pseudoscalar contributions with tree-level resonance exchanges to predict distinct resonance structures across strangeness-conserving and strangeness-changing channels.

CP asymmetries in $D\to K^0_{S,L}P$ and $D\to K^0_{S,L}V$ decays

This paper derives time-dependent and time-integrated CP asymmetry formulas for $D\to K^0_{S,L}P$ and $D\to K^0_{S,L}V$ decays by incorporating $D^0-\overline D^0$ mixing and $K^0_L$ modes, uses a global fit of branching fractions to extract hadronic parameters, and demonstrates that these effects can reach $\mathcal{O}(10^{-3})$ while mitigating theoretical tensions in specific $D^0$ decay channels.
