Soft-Dimuon Signature from Two-Component Scalar Dark Matter at the LHC

This paper investigates the Large Hadron Collider's potential to detect a two-component scalar dark matter model within a 3-Higgs Doublet framework via a soft opposite-sign dimuon plus missing energy signature, finding that while the signal shows promising statistical significance at high luminosity, the distinctive double-bump structure in the dimuon mass spectrum is insufficient to conclusively prove the two-component nature of the dark matter.

Classifying the hidden-charm pentaquarks via a flavor mixing scheme

This paper proposes a flavor mixing scheme to classify molecular hidden-charm pentaquarks formed by ground single-charm baryons and anti-charmed mesons, successfully explaining observed $P_c$ and $P_{cs}$ states while predicting the existence and mass spectra of new single- and double-strange bound states driven by specific channel mixings.

Spin Femtoscopy: A Framework for Revealing Genuine Spin Correlations

This paper proposes "spin femtoscopy," a novel framework that utilizes spin-resolved femtoscopic correlation functions of particle pairs (such as $\Lambda\Lambda$ ) to experimentally access and disentangle genuine two-particle spin correlations from quantum statistical and final-state interaction effects in relativistic heavy-ion collisions.

Gradient Flow Renormalization Schemes for Composite Fermion Operators

This paper introduces nonperturbative gradient flow renormalization schemes for composite fermion operators using partially conserved axial and conserved vector currents to simplify lattice calculations and enable the determination of renormalization factors and the strange quark mass without requiring backward-flow constructions.

Isospin-breaking effects in inclusive hadronic $\tau$ data for the muon $(g-2)$ from first principles

This paper presents a first-principles Lattice QCD+QED strategy to calculate isospin-breaking effects in inclusive hadronic $\tau$ decays, essential for improving the precision of the muon $(g-2)$ determination, by separating radiative corrections into infrared-safe classes and addressing challenges in Euclidean-to-Minkowski analytic continuation and renormalization.

The Negative- $\Sigma\bar{\Sigma}$ Angular-Parameter Puzzle in $J/\psi$ and $\psi(2S)$ Decays

This paper resolves the negative $\Sigma\bar{\Sigma}$ angular-parameter puzzle in $J/\psi$ and $\psi(2S)$ decays by demonstrating that a model incorporating $SU(3)_F$ -breaking octet contributions and common final-state interactions mixing S- and D-wave amplitudes successfully fits the data, whereas an exact $SU(3)_F$ singlet description fails decisively.

QCD sum-rule determination of the axial-vector mixing angle in the \texorpdfstring{ $B_c(1P)$ }{Bc(1P)} sector

Using QCD sum rules, this paper determines the mixing angle between the $1^1P_1$ and $1^3P_1$ axial-vector states in the $B_c(1P)$ sector to be $(43.3\pm0.2)^\circ$ , indicating significant mixing between these two states.

Charmonium-nucleon femtoscopy as a possible probe of the nucleon gravitational form factor

This paper proposes using charmonium-nucleon femtoscopy as a probe of the nucleon's gravitational form factors by constructing an effective potential from lattice-QCD data and HAL QCD constraints to evaluate correlation functions sensitive to the nucleon's $D$ -form factor.

KineticXGPU: A Tensorized Collision Operator for Dark-Sector Self-Scattering

This paper introduces KineticXGPU, a PyTorch-based, GPU-accelerated implementation of a tensorized $2\to 2$ elastic collision operator for dark-sector self-scattering, which demonstrates how strong interactions drive bimodal freeze-in distributions toward Maxwell-Boltzmann equilibrium while offering significant computational advantages over CPU-based methods.

70 years of Doubly-Logarithmic Approximation

This paper commemorates the 70th anniversary of the Doubly-Logarithmic Approximation (DLA) by reviewing its historical development from Sudakov's 1956 discovery to its modern applications in describing high-energy processes within QED, QCD, and electroweak theory.
