This paper presents a nonperturbative analytic framework for multifield inflation that resums strong curvature-isocurvature mixing to all orders, deriving exact bispectrum expressions that reveal dramatic enhancements and distinctive scaling laws in the strong-mixing regime where conventional perturbation theory fails.
This paper systematically investigates -wave interactions between ground-state bottom baryons and antibottom mesons using a one-boson-exchange model with coupled-channel effects, predicting a rich spectrum of positive-parity hidden-bottom molecular pentaquark candidates in both isospin and sectors to guide future experimental searches at LHCb and Belle II.
By fitting a leading-twist hotspot model to exclusive production data from HERA, this study precisely determines the proton's gluon cloud shape as a perturbative Gaussian core of 0.105 fm surrounded by a non-perturbative exponential halo of 0.220 fm, achieving an excellent fit with .
This paper proposes a model-independent, data-driven method to extract the photon distribution function at the Electron--Ion Collider by utilizing a cross-section-ratio-based inversion technique that transforms the standard factorization convolution into a multiplicative form while accounting for soft-photon radiation, finite-bin-width effects, and experimental acceptance.
This paper investigates the exclusive electroproduction of heavy quark-antiquark pairs off unpolarized nucleons by calculating structure functions in terms of gluon Generalized Transverse Momentum Dependent distributions (GTMDs) and Generalized Parton Distributions (GPDs) at leading order, introducing a new Lorentz-basis decomposition of the gluon-gluon correlation matrix to clarify helicity contributions relevant for future Electron Ion Collider experiments.
This paper proposes a self-consistent single-fluid relativistic mean-field framework for dark matter-admixed neutron stars using a Higgs-portal model with a massive mediator, demonstrating how the resulting repulsive interaction dynamically couples baryonic and dark matter sectors to systematically soften the equation of state, reduce maximum stellar mass, and establish a direct link between collider-motivated WIMP models and multimessenger astrophysical constraints.
This paper computes the relativistic correction to the high-energy resummed coefficient function for exclusive heavy quarkonium photoproduction, finding that while the correction itself is negligible at the physical mass scale, it significantly improves prediction robustness by partially canceling the factorization scale dependence of the leading-order relativistic correction.
The paper introduces LQCDMaster, an agentic scientific computing system that automates the conversion of natural-language lattice QCD research tasks into executable PyQUDA workflows, significantly reducing implementation time while maintaining numerical precision and enabling the exploration of novel scientific calculations.
This paper introduces radiative corrections within an effective field theory framework for neutral-current (anti)neutrino-nucleon elastic scattering at GeV energies, demonstrating that these corrections are comparable in magnitude to strange quark contributions and yield excellent agreement with BNL E734 and MiniBooNE experimental data.
This paper investigates the impact of the from Supersymmetric Standard Model on the rare inclusive decay by identifying dominant Wilson coefficient contributions, validating them against experimental constraints, and demonstrating that and interference terms primarily govern the forward-backward asymmetry.
