This paper reviews recent progress in the hadronic light-by-light contribution to the muon and presents new holographic QCD predictions, particularly regarding tensor-meson contributions, which offer a potential resolution to the tension between lattice and data-driven results by yielding a sizable positive contribution consistent with short-distance constraints.
This paper investigates the parameter space for a vanishing effective Majorana mass in a sterile neutrino framework, demonstrating that while cosmological bounds on the sum of neutrino masses constrain the sterile mixing angle and lightest active neutrino mass, the resulting cancellation mechanism renders the sterile mixing angle insensitive to the high-precision solar oscillation measurements expected from the JUNO experiment.
This paper analyzes 7 TeV LHCb Collaboration data on two- and three-pion Bose-Einstein correlations by combining the Glauber-Lachs formula with a two-component pion production model, utilizing specific pion exchange functions extended into four-dimensional Euclidean configuration space.
This paper analyzes the production of doubly heavy quarkonia ( and charmonia) via the top-quark decay channel within the NRQCD framework, revealing significant decay widths that could yield thousands of events annually at the LHC and offering a sensitive probe for validating the narrow-width approximation.
This paper presents a systematic classification of general static solutions to the source-free SU(2) Yang-Mills equations by employing a vector potential extraction approach that explicitly incorporates spin operators, yielding a comprehensive ansatz that recovers known solutions and reveals new configurations for non-perturbative studies.
This paper provides an updated overview of the symmetry-preserving Contact Interaction model, demonstrating its effectiveness in describing the mass spectra and elastic form factors of forty mesons and their diquark partners while evaluating its performance against recent literature and lattice QCD, and highlighting its potential for future applications in light of upcoming experimental data from FAIR, Jefferson Lab, and the Electron Ion Collider.
This paper assesses the detectability and constraints on global cosmic strings and their resulting Nambu-Goldstone bosons by employing semi-numerical methods to model their energy density and matter power spectrum, then comparing these predictions against observations from the cosmic microwave background, Lyman- forest, large-scale structure, and UV luminosity functions to derive limits on the boson mass and symmetry-breaking scale.
This paper proposes a unified tachyonic AdS/QCD framework, utilizing a color dielectric function driven by a tachyon field, to determine the strong running coupling and its -function across both ultraviolet and infrared regimes, successfully reproducing perturbative and nonperturbative QCD behaviors respectively.
This paper presents a 63-day cosmic-ray scattering experiment using Resistive Plate Chambers to simultaneously measure secondary cosmic-ray composition with high precision and establish stringent constraints on muon-philic dark matter scattering cross-sections.
Using the gradient expansion formalism, this paper presents a detailed parameter scan of gravitational wave production in pure axion inflation and finds that detectable signals require strong backreaction regimes that conflict with current constraints on dark radiation (), thereby defining a critical target for future lattice studies.
