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.
This paper proposes that future gamma-ray observatories can detect and distinguish asteroid-mass primordial black holes as dark matter candidates by identifying unique spectral signatures from the trident decay of dark photons (with mass 1 MeV) produced via Hawking radiation.
This paper proposes that the appropriate initial condition for hydrodynamic evolution in small collision systems is characterized by the Wehrl entropy derived from the coarse-grained Husimi distribution of the partonic Wigner function, thereby bridging the gap between the quantum nature of hadronic structure and the classical requirements of hydrodynamics.
This paper proposes a framework for creating a portable, community-maintained agentic harness for High Energy Physics by promoting stable workflow components into versioned scientific operations with common protocols and machine-readable contracts to overcome interoperability challenges across different models and tools.
This paper presents the first computation of solar capture and evaporation rates for spin-dependent dark matter-neutron scattering, demonstrating that the resulting constraints on annihilation channels can surpass direct detection limits and, in models with long-lived mediators, probe below the neutrino fog.
This paper demonstrates that Belle II can precisely measure neutrino electroweak couplings and separate their chiral structures using the mono-photon process, while also identifying this interaction as an irreducible background for dark boson searches at high luminosities.
This paper proposes a novel laboratory strategy to detect axion-like particles by utilizing third-harmonic generation from colliding high-intensity laser beams, which enables resonant enhancement of the axion-photon conversion rate through beam angle tuning to probe previously unexplored regions of axion parameter space.
This paper identifies two late-time evolutionary regimes for accreting axion clouds around compact objects—a collapse-driven "Bosenova" and a saturation regime—and demonstrates that the latter produces distinct, stable spectral lines that can be used to probe the global structure of the axion potential and its ultraviolet completion through terrestrial detection.
This paper demonstrates that combining the recursive soft drop technique from jet substructure physics with the CATHODE anomaly detection method enables the simultaneous detection of physics beyond the Standard Model signals with an arbitrary number of jets, overcoming previous limitations that restricted such searches to two-jet resonances.
This paper proposes a machine learning-based surrogate model to efficiently approximate the computationally intensive nonlinear QCD evolution of dipole-nucleus scattering amplitudes, thereby enabling rigorous global analyses of dense nuclear matter and small-x gluon distributions across diverse experimental datasets.
This paper presents a data-driven model explaining -process production patterns in metal-poor stars as mixtures of two distinct components, suggesting that Pattern 2 arises from regular neutron star mergers while Pattern 1 results from a superposition of various events, thereby offering new theoretical insights into stellar classification and highlighting the need for further observational verification.
