hep-ph papers | Gist.Science

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.

Paucity of downward UHE neutrino tracks in IceCube versus unexpected huge KM3-230213A event: solving the puzzles?

This paper proposes that the KM3-230213A event's extreme energy and the scarcity of similar downward tracks in IceCube may result from detector geometry distortions misidentifying atmospheric muons as ultra-high-energy neutrinos, while also suggesting that future re-observations could validate new Tau neutrino astronomy and Z-boson resonance models for distant cosmic sources.

Heavy Quarkonium Spectrum and Decay Constants from a Neural-Network-Based Holographic Model

This paper introduces a neural-network-based holographic model that learns the dilaton field directly from experimental data to successfully reproduce both the heavy quarkonium mass spectrum and the monotonic suppression of leptonic decay constants, overcoming limitations of traditional analytic ansätze.

PeV neutrons as origin of separated SS433 TeV signals

This paper proposes that the distant, separated TeV gamma-ray signals observed from the SS433 binary system originate from a century-old eruption of PeV relativistic neutron beams, whose beta decay produced high-energy electrons that subsequently generated gamma rays via Inverse Compton Scattering.

The next-to-leading order of the differential cross-section of the subprocess of Compton scattering of quark-gluon of prompt photon production in proton-proton collisions at NICA energies

This paper presents a next-to-leading-order calculation of the differential cross-section for prompt photon production via quark-gluon Compton scattering in proton-proton collisions at NICA energies, demonstrating that higher-order corrections contribute approximately 15% to the cross-section and are more sensitive to proton polarization than leading-order results.

LeWRON: Agentic Analysis of Electroweak Phase Transitions

The paper introduces LeWRON, an agentic framework that automates the complex, convention-sensitive pipeline for analyzing electroweak phase transitions—from Lagrangian input to gravitational-wave predictions—while ensuring reproducibility and supporting both the verification of published results and the discovery of new beyond-the-Standard-Model scenarios.

Cooling, conduction, compact objects: Gravothermal evolution of dissipative self-interacting dark matter halos

This paper extends the N-body formalism for self-interacting dark matter to include energy dissipation, revealing that radiative cooling qualitatively alters gravothermal evolution by suppressing isothermal core formation and enabling the explanation of compact objects like the JVAS B1938+666 lens perturber with shorter evolution times or smaller cross sections.

Partial-wave unitarity and long-range interactions

This paper resolves the obstruction to partial-wave unitarity bounds in theories with massless particles by developing a modified perturbation theory that incorporates off-shell Coulomb modes, thereby rendering partial-wave amplitudes well-defined, renormalization scale independent, and free of spurious infrared regulator dependence.

Eppur non si trovano Vol. 3: Phoebe -- a Mirage of a Primordial Black Hole

This paper refutes the claim that the star "Phoebe" in the Large Magellanic Cloud was a microlensing event caused by a primordial black hole, demonstrating instead that its observed brightenings are characteristic of an ordinary variable star, thereby resolving tensions with previous constraints on dark matter composition.

Reheating as a variational probe of cosmological observables

This paper proposes a variational framework that treats reheating as a constrained optimization problem to identify equation-of-state histories that extremize specific cosmological observables, demonstrating that different signals like gravitational waves and primordial black holes select distinct regions of post-inflationary expansion histories without relying on microscopic models.

Vistas: A Visualization Interface for Particle Collision Simulations

The paper introduces Vistas, an interactive, browser-based 3D visualization tool built on the Phoenix framework that enables intuitive exploration of high-energy particle collision simulations from Pythia by allowing users to toggle, filter, and inspect distinct computational stages such as parton showers and hadronization for educational purposes.
