Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.
At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
Using a holographic AdS/QCD model, this paper demonstrates that introducing an energy scale in anti-de Sitter space alters the topological class of black holes, thereby mapping the confined-deconfined phase transition to a change in topological charge that occurs at a finite critical temperature via the Hawking-Page transition.
This paper proposes that six-dimensional primordial black holes with masses ranging from sub-gram to grams, stabilized by the memory burden effect or near-extremality in a TeV-scale extra dimension framework, can serve as dark matter candidates while offering distinctive signatures for detection at future colliders and atmospheric neutrino experiments.
This paper provides direct experimental evidence for quark confinement within the proton by demonstrating that the force between quarks is attractive and constant across a wide range of positions, derived from available data and Quantum Chromodynamics.
This paper employs the local operator-product-expansion method to independently derive twist-2 relations, specifically a Wandzura-Wilczek-like relation and a Burkhardt-Cottingham-like sum rule, for the twist-3 tensor-polarized distribution function of spin-1 hadrons, thereby providing a robust theoretical foundation for upcoming electron-deuteron deep inelastic scattering experiments at JLab.
By employing a Bayesian weighting framework that integrates multimessenger observations (including GW170817, NICER, and candidate compact objects) with hybrid equations of state, this study determines that the maximum neutron star mass is robustly constrained to approximately 2.2–2.3 solar masses while the corresponding radius depends more strongly on the underlying hadronic model, typically falling near 12 km.
This paper presents predictions for coherent and incoherent J/ψ production in oxygen and neon ultra-peripheral collisions using an impact-parameter-dependent color glass condensate framework, demonstrating that these measurements can constrain small-x nuclear structure and reveal systematic saturation effects that increase with nuclear mass and energy.
This paper reinterprets existing and projected limits on axion-like particles coupling to photons as novel constraints on massive spin-2 graviton-like particles, revealing that future experimental setups could achieve unprecedented sensitivity to light graviton-like dark matter and offering a complementary search strategy for TeV-scale resonances.
The absence of predicted multimessenger signals, such as pre-burst gamma rays and lower-energy neutrinos, strongly disfavors the hypothesis that the KM3-230213A event originated from the evaporation of a nearby primordial black hole in a minimal 4D Schwarzschild scenario.
This paper proposes a non-supersymmetric baryogenesis mechanism where nonlinear dynamics of a complex scalar field with -breaking potentials dynamically generate a baryon asymmetry from symmetric initial conditions, with one specific potential model offering a mass-independent, predictive framework capable of explaining the observed baryon-to-photon ratio.
This paper presents a comprehensive formulation for calculating the angular power spectrum of cosmic background photons from dark matter decay or annihilation, emphasizing the critical role of detector energy resolution, and applies this framework to observational data across infrared, optical, X-ray, and gamma-ray wavelengths.
