Multi-Field Dilaton Screening Beyond the Thin-Shell Mechanism

This paper demonstrates that in multi-field scalar-tensor theories, the interaction between a dilaton and an axion can achieve robust screening of cosmologically light scalars through a "BBQ mechanism" that cancels exterior gradients, thereby decoupling the thin-shell localization effect from force suppression and reopening viable parameter space for strongly coupled dilatons that evade single-field no-go arguments.

Light double-gluon hybrid states

Using QCD sum rules with nonperturbative effects up to dimension twelve, this paper investigates light double-gluon hybrid mesons to determine the masses and current couplings of various qˉGGq\bar{q}GGq, qˉGGs\bar{q}GGs, and sˉGGs\bar{s}GGs configurations with specific quantum numbers, providing theoretical predictions to guide future experimental searches.

Fine Structure and Decays of Hidden-Strangeness Tetraquarks in the Dynamical Diquark Model

This paper analyzes the fine structure and decay patterns of hidden-strangeness tetraquarks within the dynamical diquark model, identifying several established and potential resonances as tetraquark candidates while providing predictions for 28 states and their experimentally accessible decay channels to guide future searches at facilities like GlueX and BESIII.

An End-to-end Architecture for Collider Physics and Beyond

This paper introduces ColliderAgent, the first language-driven, multi-agent system that autonomously executes end-to-end collider phenomenology workflows—from theoretical Lagrangians to detector-level analyses and exclusion limits—by leveraging a decoupled architecture and the Magnus execution backend to enable scalable, reproducible, and package-agnostic research in high-energy physics.

Calculation for Electric Dipole Moments of Lepton and Neutron in the N-B-LSSM via the Mass Insertion Approximation

This paper calculates the one-loop electric dipole moments of leptons and the neutron within the N-B-LSSM framework using the Mass Insertion Approximation, deriving analytical expressions that reveal their dependence on specific CP-violating phases and demonstrating that the model's predictions can satisfy current experimental limits across a reasonable parameter space.

Residual group-like symmetries in selection rules without group actions

This paper demonstrates that loop-induced group-like symmetries, termed "groupification," remain exact in theories with fusion algebras derived from finite group conjugacy classes, thereby ensuring the naturalness of non-invertible selection rules and revealing approximate discrete symmetries that control coupling magnitudes in heterotic string theory.

Higher order perturbative and nonperturbative QCD corrections on the proton structure functions and parity violating electron asymmetry

This paper investigates the impact of higher-order perturbative (up to NNLO) and nonperturbative (target mass and higher-twist) QCD corrections on proton structure functions and parity-violating electron asymmetry, providing numerical results for JLab energies to aid future analyses at the Electron Ion Collider and EicC.

Spectroscopic Properties of the Molecular Tcc+T_{cc}^{+} Meson in a Thermal Medium

This study utilizes Thermal QCD Sum Rules to investigate the Tcc+T_{cc}^{+} molecular state, revealing that its mass, decay constant, and width remain stable up to approximately 120 MeV before undergoing significant changes near the deconfinement temperature, thereby offering critical insights into QCD phase transitions and the behavior of exotic mesons in hot, dense matter.

b→cb \to c semileptonic sum rule: exploring a sterile neutrino loophole

This paper investigates whether a massive sterile neutrino could explain the discrepancy between BB-meson and Λb\Lambda_b-baryon decay anomalies by revisiting the b→cb \to c semileptonic sum rule, concluding that the induced effects are too small to resolve the tension and thus the sum rule remains a robust consistency check for experimental data.
