Dispersion relations of deeply virtual Compton scattering: investigating twist-4 kinematic power corrections

This paper demonstrates that including twist-four kinematic power corrections modifies the subtracted constants in deeply virtual Compton scattering dispersion relations, causing the helicity-conserving amplitude to depend on double distributions in addition to the $D$ -term, a mixing effect that significantly impacts the extraction of pressure forces from Jefferson Lab data.

Constraining the Energy Momentum Tensor through DVCS Dispersion Relation beyond Leading Power

This paper demonstrates that kinematic power corrections in deeply virtual Compton scattering dispersion relations provide a novel experimental constraint on nucleon momentum, pressure, and total angular momentum distributions, with continuum and lattice-QCD predictions indicating that momentum distributions account for approximately one-third of the signal at $Q^2 = 2\textrm{GeV}^2$ .

Fair Universe Higgs Uncertainty Challenge

This paper describes the "Fair Universe Higgs Uncertainty Challenge," a pioneering competition in high-energy physics and machine learning that focused on developing analysis techniques to accurately measure uncertainties and provide credible confidence intervals for the $H \rightarrow \tau^+\tau^-$ cross-section, with results now publicly available on Zenodo.

High Quality QCD Axion in the Standard Model

This paper proposes a minimal framework utilizing the discrete gauge symmetry $\mathbb Z_4 \times \mathbb Z_3$ , motivated by the Standard Model's internal structure, to naturally resolve the axion quality problem while simultaneously explaining neutrino masses, baryon asymmetry, and dark matter.

Local gauge invariant operator on isometry breaking background

This paper proposes constructing local gauge invariant operators on isometry-breaking backgrounds via the Stückelberg mechanism—effectively introducing physical clocks and rods—but argues that suppressing the resulting spacetime fluctuations to reliably define operators in localized regions (such as black hole islands) requires strong isometry breaking, potentially achieved through transitions to higher-dimensional black holes.

Beyond Leading Logarithms in $g_V$ : The Semileptonic Weak Hamiltonian at $\mathcal{O}(α\,α_s^2)$

This paper presents the first next-to-leading-logarithmic QCD analysis of electromagnetic corrections to the semileptonic weak Hamiltonian, calculating mixed $\mathcal{O}(\alpha\alpha_s^2)$ corrections to the vector coupling $g_V$ to yield a refined radiative correction value that enhances the consistency of first-row CKM unitarity tests.

Probing Azimuthal Alignment in Heavy-Ion Collisions: Clusterization Effects

This study utilizes the HYDJET++ model to demonstrate that the high degree of azimuthal alignment observed in cosmic-ray experiments is also present at the level of energetic particle clusters, highlighting how clustering procedures and momentum conservation jointly shape these correlations in high-multiplicity heavy-ion collisions.

Axial-vector molecules $ΥB_{c}^{-}$ and $η_{b}B_{c}^{\ast-}$

Using QCD sum rules, this study calculates the mass and width of the axial-vector hadronic molecules $\mathcal{M}_{\mathrm{AV}}$ and $\widetilde{\mathcal{M}}_{\mathrm{AV}}$ with quark content $bb\overline{b}\overline{c}$ , predicting a mass of approximately 15.8 GeV and an unstable width of about 114 MeV to guide future experimental searches for fully heavy molecular structures.

Trigonometric continuous-variable gates and hybrid quantum simulations of the sine-Gordon model

This paper introduces a new universality paradigm for hybrid qubit-qumode quantum computing based on trigonometric continuous-variable gates, demonstrating their effectiveness through a deterministic ancilla-based implementation and a successful simulation of the lattice sine-Gordon model, including ground state preparation, real-time dynamics, and kink profile extraction.

Constructing Dimension-8 SMEFT from Conserved Currents

This paper introduces the Kinematically Diagonalized Current Basis (KDCB), a generative framework that constructs dimension-8 SMEFT operators from conserved Noether currents to resolve kinematic mixing, ensure unique energy scaling in scattering amplitudes, and facilitate the application of positivity bounds and global fits for interpreting new physics.
