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 investigates the internal structure of light pseudoscalar mesons (pion and kaon) using spin-improved power-law wave functions to calculate various distribution functions and form factors, finding that quarks and antiquarks carry only 41% of the longitudinal momentum at 16 GeV² while the predicted electromagnetic charge radii and vector form factors align well with experimental data.
This paper evaluates pion-induced QED radiative corrections to the inverse beta decay cross section using heavy baryon chiral perturbation theory, demonstrating that these effects are small enough to enable sub-permille theoretical precision for antineutrino energies above 10 MeV.
This paper demonstrates that incorporating vector-like bottom quarks into the Type-II Two-Higgs-Doublet Model introduces hidden heavy Higgs decay channels that significantly weaken current LHC mass constraints, lowering the exclusion limit for singlet and doublet configurations from approximately 1.5 TeV to as low as 0.98 TeV.
This paper presents a symmetry-preserving approximation for computing light meson spectra that incorporates fully-dressed quark-gluon vertices and demonstrates significantly improved agreement with experimental masses compared to the traditional rainbow-ladder approximation.
This paper utilizes a two-zone photohadronic model to explain the July 2014 VHE flaring of Markarian 501, attributing the observed narrow peak-like feature around 3 TeV on July 19 to a spectral cutoff at 3.18 TeV rather than an anomalous emission mechanism.
This paper derives a universal formula for the anomalous scaling of multipole moments in classical general relativity using effective field theory methods, demonstrating that this scaling is determined by gravitational wave phase shifts and proposing a novel resummation of universal short-distance logarithms to improve gravitational waveform modeling for compact binary systems.
Using the largest sample to date of nearly 100 Milky Way-like galaxies from the TNG50 simulation and a novel phase-space scaling procedure, this study demonstrates that astrophysical uncertainties in dark matter velocity distributions result in cross-section limits varying by only ~60%, a level comparable to or smaller than the systematic uncertainties of current ton-scale direct detection experiments.
This paper derives a closed formula for 5D Schwarzschild-Tangherlini black hole scalar wave scattering using the Nekrasov-Shatashvili function and computes non-vanishing, renormalization group running tidal Love numbers up to by matching effective field theory with ultraviolet solutions.
This paper calculates next-to-leading order nuclear matrix elements for two-neutrino double-beta decay to excited states in key isotopes using the nuclear shell model, finding that while NLO corrections are typically small, they can become significant due to leading-order cancellations, and that nuclear deformation and seniority structure critically influence the predicted half-lives.
This paper analytically derives the concurrence for mixed qubit states in relativistic scattering, demonstrating that the leading-order entanglement depends on the real part of the inelastic forward amplitude and the initial state, while also revealing a connection between this amplitude and the reduction of linearized entropy.
