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.

Out-of-equilibrium contributions to charm hadrons in a fluid-dynamic approach

This paper extends the fluid-dynamic description of charm quarks in the quark-gluon plasma by incorporating out-of-equilibrium corrections from both the initial free-streaming phase and the freeze-out surface, enabling precise calculations of charm hadron yields and momentum distributions to systematically determine transport coefficients while validating the model against experimental data and defining its kinematic limits.

The Potential of HEFT and the scale of New Physics

This paper employs a geometric framework to derive closed-form expressions for high-energy scattering amplitudes in theories with Nambu-Goldstone bosons and a Higgs-like scalar, using these results to characterize the relationship between HEFT and SMEFT and identify a dilaton-based model that offers a unique decoupling limit connecting HEFT directly to the Standard Model.

Neutron Star Equation of State with Nucleon Short-Range Correlations: A Concise Review and Open Issues

This concise review examines how nucleon short-range correlations and their resulting high-momentum tails modify the kinetic and interaction contributions to the neutron star equation of state, thereby influencing macroscopic observables such as mass-radius relations and tidal deformabilities, while summarizing current constraints and outlining open questions for future research.

Quantitative Understanding of PDF Fits and their Uncertainties

This paper establishes a theoretical framework based on the Neural Tangent Kernel to analytically describe the training dynamics and uncertainty propagation of neural network-based Parton Distribution Function fits, thereby providing a powerful diagnostic tool to assess the robustness of current methodologies and bridge particle physics with machine learning theory.

Radiative return at NLOPS accuracy

This paper presents a next-to-leading order (NLO) calculation matched to a Parton Shower (PS) for the radiative return processes e+e−→X+X−γe^+e^-\to X^+X^-\gamma (with X=π,μX=\pi, \mu), implemented in the updated BabaYaga@NLO Monte Carlo generator to enable precision measurements of the pion form factor for the muon anomalous magnetic moment.

Putting Jet Substructure on Track(s)

This paper presents the first complete theoretical calculations of jet substructure observables on tracks at the Large Hadron Collider, utilizing factorization theorems and renormalization group techniques to compute projected energy correlators up to four points at next-to-leading collinear logarithmic accuracy, thereby enabling precise comparisons between experimental tracking data and theory.

Production of Magic States via ZZ Bosons and Dark Photons

This paper investigates the production of magic states in both the electroweak sector of the Standard Model and a dark sector extension, revealing how high-energy regimes and new massive mediators generate distinct magic distribution functions and reorganize stabilizer state classes, with specific processes exhibiting maximal magic at particular mass ratios.
