This paper demonstrates that Nelson-Barr models utilizing vector-like quark doublets offer a phenomenologically viable solution to the strong CP problem by leveraging an accidental symmetry to delay leading contributions to until three loops, thereby naturally suppressing hadronic CP violation.
This paper investigates the collider phenomenology of feebly interacting dark matter produced via a spin-2 portal, demonstrating that machine learning-enhanced searches at the High-Luminosity LHC can effectively probe cosmologically viable freeze-in parameter space through Vector Boson Fusion channels.
The paper proposes a non-redundant, ordered, and family-unified quark flavor structure derived from hierarchical quark masses that offers a potential replacement for the Standard Model's unclear Yukawa interactions by revealing new insights into both the mass matrix and CKM mixing.
This paper proposes using gravitational tidal effects, such as apsidal motion and orbital precession, to constrain the internal chemical and structural compositions of low-eccentricity, short-period pulsar companions, thereby shedding light on their unique formation histories.
This paper argues that the non-trivial topological structure of the Euclidean Schwarzschild black hole manifold supports non-trivial electromagnetic configurations that, through the electromagnetic -term, induce $CP$-asymmetric Hawking radiation manifested as an imbalance between left- and right-polarized photons.
This paper introduces a Physics-Guided Neural Network that integrates Holographic QCD principles with deep learning to accurately model the proton structure function across non-perturbative and transition regimes, achieving a high-precision fit to SLAC data while dynamically identifying the kinematic crossover between hadronic resonances and holographic Pomeron exchange.
This paper investigates quantum correlations in top quark-antiquark pairs produced via QCD processes by employing measures such as quantum mutual information and coherence to establish their dependence on kinematic variables and initial mixing probabilities, thereby offering new insights into systemic quantumness in high-energy physics.
This paper derives quantum gravity contributions to the beta functions of gauge and Yukawa couplings using the Schwinger proper-time flow equation, analyzing their dependence on unphysical parameters and evaluating their potential to generate observable low-scale predictions in the Standard Model and beyond.
This paper proposes a type-I seesaw model with a keV-scale scalar mediator that resolves the tension between cosmological hints for neutrino self-interactions and terrestrial constraints by having active neutrinos resonantly convert into self-interacting dark radiation after Big Bang Nucleosynthesis, thereby mimicking the desired cosmological signal while evading laboratory limits.
Using precise data from the BESIII collaboration, this paper presents compelling evidence for a subthreshold pole in the process with a mass of approximately 3896 MeV, suggesting its identification as the state.
