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 study combines 14 years of Fermi-LAT and 10 years of H.E.S.S. observations of the galactic center to establish stringent constraints on dark matter annihilation into gamma-ray lines, demonstrating that Fermi-LAT provides the tightest limits for masses below 300 GeV while H.E.S.S. dominates for masses above 1 TeV, collectively probing energy scales up to 10–20 TeV.
This paper generalizes soft and collinear factorization in perturbative QCD to multi-collinear configurations, demonstrating how generalized splitting amplitudes encode the breaking of strict collinear factorization in space-like limits and the failure of naive multiplicative factorization in simultaneous soft-collinear regimes.
By analyzing 2693 rotation-curve measurements from 153 SPARC galaxies within a unified radial framework defined by baryonic acceleration, the study reveals a galaxy-independent dark-matter halo structure characterized by a universal density profile (), a linear mass growth with radius, and a constant rotation velocity beyond a specific scaled distance.
This paper introduces an iterative, algorithmic framework that utilizes Dyck paths and Stieltjes-Rogers polynomials to systematically generate all self-energy Feynman diagrams for the single-polaron problem with arbitrary linear coupling, thereby enabling efficient, unbiased diagrammatic Monte Carlo simulations by eliminating stochastic weighting across topologies.
This paper investigates charged lepton flavor violating interactions with a pair of light dark matter particles within an effective field theory framework, deriving kinematic distributions to distinguish operator structures and dark matter masses, establishing stringent limits from current experimental data, and demonstrating that future observations of muonium invisible decays could serve as a compelling signature for these flavored dark matter interactions.
This paper demonstrates that imposing the CP-violation constraint, specifically the Jarlskog invariant, on a nearly democratic quark mass matrix ansatz reduces the number of free parameters from six to five, thereby establishing an explicit interdependence among the six up- and down-quark mass eigenvalues.
This paper honors Henry Primakoff by reviewing his legacy and recent experimental tests of Chiral Perturbation Theory via Primakoff reactions at CERN and Jefferson Laboratory, which confirm two-flavor predictions while highlighting the need for future measurements with kaons and eta mesons to validate three-flavor theories involving strange quarks.
This paper investigates the scattering of non-relativistic finite-size particles using the partial wave method to demonstrate how particle size significantly alters interaction potentials and cross sections, revealing non-perturbative effects in puffy dark matter direct detection that depend on the size-to-range ratio and offering stability-based constraints for nugget-type dark matter.
This paper investigates the feasibility of observing the muon trident process, including the first potential detection of electromagnetic pair production and QED bound states, at the LHC's far-forward FASER and FASER2 detectors through -tungsten collisions.
This paper constrains the process with in the low-mass region by recasting Standard Model measurements, establishing cross-section limits between 0.12 and 0.62 pb while identifying a notable preference for a new physics signal around GeV and GeV that can be accommodated within a top-philic two-Higgs-doublet model.
