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.

PDFxTMDLib: A High-Performance C++ Library for Collinear and Transverse Momentum Dependent Parton Distribution Functions

This paper introduces PDFxTMDLib, a modern, high-performance C++ library that overcomes the customization and uncertainty analysis limitations of existing tools like LHAPDF and TMDLib by providing a flexible framework for both collinear and transverse momentum dependent parton distribution functions, which is validated through integration with the PYTHIA event generator and comparative studies.

Exploring the BSM parameter space with Neural Network aided Simulation-Based Inference

This paper demonstrates that likelihood-free Simulation-Based Inference, particularly the Neural Posterior Estimation method, offers a computationally efficient and accurate alternative to traditional MCMC for exploring high-dimensional Beyond the Standard Model parameter spaces, successfully inferring posterior distributions for both 5-parameter and 9-parameter pMSSM scenarios including dark matter constraints.

Light Vector Dark Matter via a Magnetic Dipole Portal: Bridging Direct Detection and Fixed-Target Searches

This paper proposes a sub-GeV vector dark matter model mediated by a magnetic dipole portal arising from a broken non-Abelian SU(2)DSU(2)_D symmetry, demonstrating that a significant parameter space consistent with thermal relic abundance and current constraints remains viable and highlights the necessity of combining fixed-target, direct detection, and cosmological searches for comprehensive discovery.

Linear realization of SU(3) parity doublet model for octet baryons with bad diquark

This paper constructs a linear SU(3)L×SU(3)RSU(3)_L \times SU(3)_R parity doublet model for octet baryons that, by incorporating the (3,6)+(6,3)(3,6) + (6,3) representation containing "bad" diquarks alongside the dominant (3,3ˉ)+(3ˉ,3)(3,\bar{3}) + (\bar{3},3) representation, successfully reproduces the ground-state mass hierarchy (including the Σ\Sigma-Ξ\Xi ordering) and predicts the spectrum of excited states up to 2.5 GeV.

Symmetric Gapped States and Symmetry-Enforced Gaplessness in 3-dimension

This paper establishes a comprehensive framework in three spatial dimensions that classifies fermionic quantum anomalies into two distinct classes—those permitting symmetric gapped phases and those enforcing gaplessness—thereby providing concrete predictions for the infrared behavior of (3+1)-dimensional gauge theories and demonstrating that discrete chiral anomalies cannot be trivialized by adding bosonic degrees of freedom.

Lazarides-Shafi axion models as Dijkgraaf-Witten theories

This paper formulates Lazarides-Shafi axion models as Dijkgraaf-Witten topological quantum field theories to derive a master formula for the domain wall number and clarify how higher-form symmetries and higher-group structures enable vacuum identification, revealing that even domain-wall-number-one scenarios exhibit nontrivial four-group structures and symmetry-protected topological phases.
