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.
This paper demonstrates that one-loop quantum corrections significantly enhance the effective self-interaction coupling of ultralight dark matter, thereby establishing tighter cosmological constraints and underscoring the necessity of accounting for these corrections in detection efforts.
This paper develops a microscopic quantum membrane paradigm for black holes by modeling the horizon as a fuzzy sphere populated by half-filled Fermi sea partons, demonstrating how their coupling to a Berry monopole generates Lowest-Landau-Level currents that dynamically lock to external fields, thereby replacing the classical fictitious membrane with a dynamical quantum structure that yields frequency- and helicity-dependent corrections to horizon boundary conditions.
Using 2+1 flavor domain wall fermion lattice QCD ensembles and a novel method involving a background electric field with single time-slice topological charge sampling to mitigate statistical noise and excited-state contamination, the authors calculate the neutron electric dipole moment to be fm after extrapolation to the physical point.
This paper proposes and investigates a comprehensive set of , , and Regge trajectory relations for the quadruply heavy pentaquark within a diquark-triquark framework, demonstrating that accounting for internal substructures is essential for defining these trajectories and providing mass estimates for various excited states.
This paper investigates low-energy scattering and femtoscopic correlations of deuteron--hyperon systems using a microscopic folding approach based on HAL-QCD potentials, predicting no bound states but significant momentum enhancements for specific channels and demonstrating that feed-down decays substantially modify observable correlations.
The paper proposes that the 220 PeV neutrino event KM3-230213A can be explained by the decay of a relic particle with a mass of GeV, where the inferred decay rate and energy scale suggest a connection to grand unification physics at approximately GeV.
This paper demonstrates that within a -symmetric Inert Doublet + Singlet Model, all four symmetry-protected scalar portals for interacting dark energy fail to simultaneously resolve the tension and satisfy technical naturalness due to extreme fine-tuning requirements, implying that viable solutions necessitate either multi-field cancellations or explicit symmetry breaking.
Using 14 years of Fermi-LAT gamma-ray data and DES Y3/DECADE galaxy shapes to perform a model-independent cross-correlation analysis over 12,000 deg², this study finds null results that constrain wino-like dark matter and thermal annihilation scenarios, while a template-based approach reveals a moderate 3σ signal with deviations from standard background expectations.
This paper demonstrates that introducing an additional derivative interaction in non-minimally coupled Proca theories can eliminate the zero-speed strong-coupling problem by restoring non-degenerate scalar dynamics, thereby identifying a stable de Sitter fixed point with a non-vanishing temporal vector condensate where no-ghost and stability conditions are satisfied.
This paper presents a LO QED Monte Carlo calculation of heavy lepton pair production cross sections in ultraperipheral gold and lead collisions at RHIC and LHC energies, incorporating neutron emission probabilities to categorize results into specific neutron classes and comparing them with experimental data from STAR, ALICE, ATLAS, and CMS under detector-specific fiducial constraints.
