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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper introduces FASTColor, a machine learning toolkit that accelerates the reweighting of leading-color to full-color QCD matrix elements by approximately a factor of two using modern neural networks, including transformers that leverage underlying symmetries to improve generalization and potentially eliminate the need for final unweighting steps.
This paper proposes that neutron stars can detect elusive lepton-flavor-violating dark matter by utilizing "flavor blocking" to prevent thermalization, thereby sustaining -wave annihilations that heat the stars to observable infrared temperatures.
This paper demonstrates that the scalar sector of a Higgs Triplet Model extended with a complex singlet strictly forbids spontaneous CP violation, as minimization conditions and global symmetries enforce a real vacuum for both non-zero and vanishing trilinear couplings.
This paper analyzes the latest LZ 2025 data to demonstrate that cosmic-ray-boosted light dark matter provides a powerful probe for sub-MeV electrophilic dark matter, yielding constraints that significantly surpass previous XENONnT limits and extend into previously unexplored regions of the light-mediator parameter space.
This paper investigates a fermionic dark matter candidate interacting via dark dipole operators mediated by a massive dark photon, finding that while cosmological observations already constrain most of the parameter space, future low-threshold semiconductor experiments like skipper-CCDs are crucial for probing sub-GeV dark matter masses that remain viable against current direct detection limits.
This paper employs QCD light-cone sum rules to calculate the static electromagnetic properties of three charm-strange molecular tetraquark candidates, revealing that their magnetic moments are dominated by light quarks while their small quadrupole moments suggest nearly spherical charge distributions, thereby providing quantitative benchmarks to distinguish molecular structures from compact multiquark interpretations.
This paper introduces a generalized framework to calculate nonperturbative effects in minimal dark matter models with Higgs-coupled multiplets, revealing that certain mixed multiplet scenarios can evade direct-detection limits below the neutrino floor, thereby demonstrating that such models cannot be fully excluded by direct-detection experiments alone.
This paper investigates how next-to-leading order radiative corrections in the MSSM can suppress Higgsino-nucleon scattering cross-sections below the neutrino floor through a specific cancellation mechanism, identifying regions where spin-independent interactions effectively vanish.
This paper proposes that at asymptotic limits of quantum gravity moduli spaces, the masses of lightest particle towers correspond to eigenfunctions of the moduli-space Laplacian with quantized eigenvalues dictated by the Emergent String Conjecture, a relationship supported by diverse supersymmetric examples and linked to instanton spectra.
The authors demonstrate that the self-correcting memory in 3d Wegner gauge theory remains stable against arbitrary small perturbations through a novel "gauge averaging" method, which reveals that the phase is fluctuation-stabilized with robustness that increases with temperature up to a critical point.
