Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper demonstrates that while the Krauss-Nasri-Trodden (KNT) model can satisfy low-energy experimental constraints, a significant portion of its viable parameter space is ruled out by vacuum stability conditions when renormalization group effects are considered, leaving most of the remaining region testable through future charged lepton flavor violating experiments.
This paper reviews the current status and future prospects of axion superradiance, a phenomenon where light bosonic fields amplify around rotating compact objects to constrain axion masses and probe non-gravitational interactions, while emphasizing the necessity of accounting for complex astrophysical environments.
This paper proposes and validates via lattice simulations a novel Grand Unified Theory-scale first-order phase transition within Starobinsky inflation, featuring a dynamically evolving potential barrier that suppresses early bubble nucleation while triggering massive nucleation at the end of inflation to successfully resolve the graceful exit problem and produce a distinctive gravitational-wave spectrum.
This paper derives a fluctuation-dissipation relation for an energetic light quark in a non-perturbative thermal gluon plasma by connecting the longitudinal drag coefficient to longitudinal and transverse diffusion coefficients and the thermal gluon condensate through complex-valued transport functions and contour-integration techniques.
This paper introduces FIONA, an efficient code that leverages Fast Fourier Transform and non-uniform fast Hankel transform techniques to rapidly evaluate Fresnel integrals for gravitational-wave lensing, achieving speedups of 2–3 orders of magnitude over existing methods for dense source grids.
This paper presents a new lattice QCD determination of the tetraquark binding energy using relativistic heavy-quark actions, yielding results of approximately $-79$ MeV that are consistent with prior NRQCD findings but exhibit reduced magnitude due to the exclusive use of symmetric correlation matrices with local four-quark operators.
Using lattice-derived quark-antiquark potentials, this study demonstrates that strong magnetic fields induce anisotropic confinement that significantly lowers the masses of radially excited quarkonium states, particularly for longitudinal spin eigenstates, thereby offering a distinct signature for future lattice verification.
This paper investigates how different holographic implementations of axial-anomaly effects, constrained by vacuum - phenomenology, critically influence the chiral phase structure and the nature of the finite-temperature transition in a -extended soft-wall holographic QCD model.
This paper investigates the potential formation of and molecular states as superflavor partners of the tetraquark using the one-boson exchange model, predicting numerous bound and resonant states whose mass spectra are significantly dependent on the uncertain coupling constant.
This paper investigates purely baryonic weak decays of heavy baryons, specifically calculating the branching fraction for the unobserved channel within the Skyrme model to test the Standard Model and potential CP violation sources.
