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.
This paper highlights the potential of discovering radio pulsars orbiting Sagittarius A* to test fundamental physics, while addressing the challenge of mass perturbations in the Galactic center by developing a numerical timing model to accurately probe spacetime and dark matter.
This paper introduces a novel Log Gaussian Cox Process (LGCP) method for modeling smooth backgrounds in high energy physics that minimizes assumptions about the underlying shape by utilizing a Gaussian process for the intensity function and Markov Chain Monte Carlo for optimization, demonstrating its effectiveness through synthetic experiments against traditional analytic functional forms.
This paper establishes the equivalence between the parametric resonance and coherent state -matrix approaches to scalar condensate decay by modifying the latter to eliminate unwanted diagrams and explicitly demonstrating their agreement at lower orders in a double expansion.
This paper demonstrates that primordial black holes retaining electric charges from the early universe, particularly near-extremal ones, can significantly alter Hawking radiation evaporation limits and thus reshape constraints on their viability as dark matter candidates.
This paper systematically classifies dimension-six baryon-number-violating SMEFT operators under various flavor-symmetry assumptions, demonstrating how their interplay with neutrino masses can allow for multi-TeV BNV scales consistent with proton decay constraints, while also identifying UV completions where the effective field theory description may be insufficient.
