This paper theoretically demonstrates that the isospin-violating reaction dynamically generates the resonance while suppressing the , a prediction that aligns with current BESIII experimental data and warrants further investigation with improved statistics.
This study demonstrates that Lorentz invariance violation, particularly through CPT-violating SME coefficients like , , , and , significantly degrades the DUNE experiment's sensitivity to CP violation by introducing parameter-specific correlations and degeneracies that reduce discovery significance below the threshold.
This paper presents updated predictions for -baryon lifetimes and their ratios within the heavy quark expansion framework by incorporating next-to-next-to-leading-order QCD corrections to free -quark decay and complete next-to-leading-order corrections to dimension-five contributions, resulting in significantly reduced theoretical uncertainties and excellent agreement with experimental data.
This paper revisits graviton production via inflaton decay during reheating to correct previous differential decay rate calculations, derive the resulting high-frequency stochastic gravitational wave background, and establish constraints from cosmological observations while projecting detection prospects for future microwave and space-based detectors.
This paper proposes a minimal gauge extension of the Standard Model featuring a two-component singlet-doublet fermionic dark matter candidate stabilized by a discrete symmetry, which successfully evades stringent direct-detection constraints while offering testable predictions for collider, indirect, and gravitational wave experiments.
This paper proposes a diagnostic method using null-response channels in space-based gravitational wave interferometers like LISA and Taiji to distinguish monochromatic signals caused by ultralight dark matter from those generated by gravitational waves.
This paper establishes constraints on dimension-six four-heavy-quark operators in the Standard Model Effective Field Theory by combining LHC top-quark and single-Higgs production data with electroweak precision observables, while highlighting the significant impact of the scheme choice on the resulting fits.
This paper validates a computationally efficient effective action approach for calculating holographic bubble nucleation by demonstrating its good agreement with direct gravity dual computations in a scalar field probe limit setup.
The paper challenges the interpretation of LEDA 1313424's nine rings as the result of a recent galaxy collision due to implausible kinematic and structural inconsistencies, and instead proposes that these rings are caustic imprints of axion dark matter forming a Bose-Einstein condensate.
This Letter proposes that the observation of a prominent Jacobian peak in the transverse momentum distribution of mesons in reactions serves as a definitive criterion to confirm the existence of the resonance and distinguish it from interference effects.
