This study utilizes a sample of 120 localized Fast Radio Bursts combined with DESI DR2 Baryon Acoustic Oscillation data and artificial neural networks to constrain the cosmic curvature parameter in a model-independent manner, finding results consistent with a spatially flat Universe while demonstrating the growing potential of FRBs as a precision cosmological probe.
This paper demonstrates that the Supersymmetric Georgi-Machacek model can explain the 95 GeV diphoton excesses observed by ATLAS and CMS through a light custodial singlet Higgs boson, but fails to simultaneously account for the LEP excess due to its highly constrained Higgs potential, which also yields sharp predictions for the remaining mass spectrum and offers distinct signatures to differentiate it from the non-supersymmetric GM model at future colliders.
This paper proposes a singlet Majoron model with an enhanced electromagnetic anomaly that simultaneously explains neutrino masses, the baryon asymmetry of the Universe, dark matter, and the formation of high-redshift supermassive black holes through the decay of eV-scale Majorons into photons.
This paper demonstrates a remarkable convergence between Basis Light-Front Quantization and Dyson-Schwinger equations in predicting charmonium light-front wave functions and associated observables, thereby validating both Hamiltonian and Lagrangian approaches for studying non-perturbative QCD structure.
This paper proposes a new QCD thermal history scenario where a heavy axionlike particle with a mass of approximately 5 MeV induces a Coleman-Weinberg type chiral phase transition via supercooling, potentially leading to unique cosmological phenomena such as mini-inflation, nonperturbative reheating, and the production of gravitational waves and primordial black holes.
This paper employs the QCD sum rule method to calculate the form factors and decay widths for the semileptonic transition of the spin-3/2 bottom baryon to the spin-3/2 charmed baryon , providing theoretical predictions to test the Standard Model against future experimental data.
This paper presents a fast and accurate detector simulation framework using Vision Transformers, Conditional Flow Matching, and Normalising Flows to emulate Geant4 results on CaloChallenge datasets, achieving minimal deviation from high-fidelity simulations while significantly improving generation speed.
This paper investigates the feasibility of extracting baryon-antibaryon generalized distribution amplitudes from the process using QCD factorization and numerical estimates, demonstrating that such a measurement is achievable at the Belle II experiment.
This paper introduces the data-driven ARGOS metric, a theoretically grounded and empirically robust tool for selecting the most sensitive anomaly detection models in a model-agnostic way, demonstrating its superiority over existing metrics like binary cross-entropy loss in tasks such as hyperparameter tuning and feature selection.
This paper updates a previously proposed strategy by incorporating charged current Drell-Yan final states alongside neutral current inputs to significantly reduce Parton Distribution Function uncertainties in high-mass Drell-Yan spectra, thereby enhancing the sensitivity of Beyond the Standard Model searches at the LHC.
