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.

Holographic Open/Closed Exchange in Double Deeply Virtual Compton Scattering: Fixed--jj Structural Matching to the ±\pm-Basis Wilson Coefficients

This paper demonstrates that in the collinear regime, holographic double deeply virtual Compton scattering (DDVCS) amplitudes derived from Witten diagrams structurally match the ±\pm-basis Wilson coefficients of perturbative QCD at a fixed scale, with the open and closed string channels corresponding to the (+)(+) and ()(-) eigenchannels respectively, governed by a universal hypergeometric hard kernel and distinct branch-point structures.

The 3-3-1 Model: a natural framework for sub-MeV dark matter

This paper demonstrates that the SU(3)C × SU(3)L × U(1)N model with right-handed neutrinos naturally provides a testable TeV-scale framework for sub-MeV dark matter, where a pseudo-Goldstone boson acquires a tiny mass via gravitational effects and achieves the observed relic abundance through freeze-in in a low-reheating temperature scenario without requiring tiny couplings.

Probing Collapsed Dark Matter Halos with Fast Radio Bursts

This paper proposes that strong gravitational lensing of Fast Radio Bursts (FRBs) by core-collapsed Self-Interacting Dark Matter (SIDM) subhalos can effectively probe small-scale dark matter structures and constrain self-interaction cross-sections, leveraging the enhanced lensing cross-sections and longer time delays predicted for these collapsed halos compared to standard Cold Dark Matter models.

Cross-Domain Transfer with Particle Physics Foundation Models: From Jets to Neutrino Interactions

This paper demonstrates that the OmniLearned particle physics foundation model, pre-trained on high-energy collision data, can be effectively transferred to low-energy fixed-target neutrino experiments to outperform models trained from scratch on tasks like energy regression and pion classification, thereby validating the potential for detector-agnostic inference across vastly different energy scales and physics processes.

Deciphering the nature of PψsΣP^{\Sigma}_{\psi s} pentaquarks in the light of their electromagnetic multipole moments

This paper utilizes QCD light-cone sum rules to calculate the electromagnetic multipole moments of Σ\Sigma-type strange hidden-charm pentaquarks, revealing distinct magnetic dipole, electric quadrupole, and magnetic octupole signatures that depend on diquark structure and provide key discriminants to differentiate between compact pentaquark and molecular interpretations.

Open-flavor threshold effects on quarkonium spectrum in the BOEFT

This paper utilizes Born-Oppenheimer effective field theory (BOEFT) to systematically quantify open-flavor threshold effects on the quarkonium spectrum by solving coupled Schrödinger equations with lattice-constrained static potentials, successfully reproducing experimental data and providing a field-theoretical interpretation of the phenomenological 3P0^3P_0 model's pair-creation constant.

Graviton Production from Inflaton Condensate: Boltzmann vs Bogoliubov

This paper systematically compares Boltzmann and Bogoliubov frameworks for graviton production from an oscillating inflaton condensate, demonstrating that while both methods agree for quadratic potentials at short wavelengths, the Bogoliubov formalism is essential for capturing significant non-adiabatic transition effects in steeper potentials (n>2n>2) that the perturbative Boltzmann approach misses.
