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.

Effects of dispersion parity-violating interaction in electron scattering and atoms

This paper proposes that a long-range parity-violating interaction mediated by the exchange of two neutrinos effectively acts as a contact term in atomic systems, producing a correction that resolves the existing discrepancy between the Standard Model prediction and experimental measurements of cesium parity violation while yielding weak mixing angle and weak charge values consistent with the Standard Model.

Strangeness neutrality and the QCD phase diagram

Using the functional renormalization group to systematically improve upon previous studies, this paper maps the QCD phase diagram at strangeness neutrality, predicting a critical end point at (92, 696) MeV and confirming consistency with both functional QCD and lattice QCD benchmarks.

Projected Sensitivity of Paleo-Detectors to Dark Matter Effective Interactions with Nuclei

This paper projects the sensitivity of paleo-detectors to various non-relativistic effective field theory dark matter-nucleus interactions, demonstrating that they offer superior or comparable discovery potential to current conventional direct detection experiments across a wide range of dark matter masses and interaction types.

history: A tool for fully-differential cross sections at next-to-next-to-leading order

The paper introduces $\texttt{history}$ , a process-independent software tool based on a fully-local nested soft-collinear subtraction scheme that calculates fully-differential cross sections for colour-singlet production in hadronic collisions up to next-to-next-to-leading order in QCD, with initial implementations for Higgs production via gluon fusion and Higgs-Strahlung.

New nonet scalar mesons and glueballs: the mass spectra and the production yields in relativistic heavy ion collisions

This paper proposes a new nonet scheme for scalar mesons ( $f_0(980)$ , $a_0(980)$ , $K_0^*(1430)$ , and $f_0(1770)$ ) as $P$ -wave quark-antiquark states while identifying $f_0(1500)$ as a glueball, supporting this classification through statistical and coalescence model calculations of their production yields in relativistic heavy ion collisions.

Electromagnetic structure of Bc and heavy quarkonia in the light-front quark model

This paper investigates the electromagnetic structure of heavy quarkonia and the $B_c$ meson using a light-front quark model with variational wave functions, finding that the electromagnetic radii of $2S$ and $3S$ states are approximately 1.5 and 1.9 times larger than their $1S$ counterparts, respectively, in agreement with lattice QCD data and other model predictions.

Multi-Field Dilaton Screening Beyond the Thin-Shell Mechanism

This paper demonstrates that in multi-field scalar-tensor theories, the interaction between a dilaton and an axion can achieve robust screening of cosmologically light scalars through a "BBQ mechanism" that cancels exterior gradients, thereby decoupling the thin-shell localization effect from force suppression and reopening viable parameter space for strongly coupled dilatons that evade single-field no-go arguments.

Light double-gluon hybrid states

Using QCD sum rules with nonperturbative effects up to dimension twelve, this paper investigates light double-gluon hybrid mesons to determine the masses and current couplings of various $\bar{q}GGq$ , $\bar{q}GGs$ , and $\bar{s}GGs$ configurations with specific quantum numbers, providing theoretical predictions to guide future experimental searches.

Fine Structure and Decays of Hidden-Strangeness Tetraquarks in the Dynamical Diquark Model

This paper analyzes the fine structure and decay patterns of hidden-strangeness tetraquarks within the dynamical diquark model, identifying several established and potential resonances as tetraquark candidates while providing predictions for 28 states and their experimentally accessible decay channels to guide future searches at facilities like GlueX and BESIII.

An End-to-end Architecture for Collider Physics and Beyond

This paper introduces ColliderAgent, the first language-driven, multi-agent system that autonomously executes end-to-end collider phenomenology workflows—from theoretical Lagrangians to detector-level analyses and exclusion limits—by leveraging a decoupled architecture and the Magnus execution backend to enable scalable, reproducible, and package-agnostic research in high-energy physics.
