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.

Temporary EHBL-like behavior of Markarian 501 during July 2014 VHE flaring

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.

Resummation of Universal Tails in Gravitational Waveforms

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.

Dark Matter Velocity Distributions for Direct Detection: Astrophysical Uncertainties are Smaller Than They Appear

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.

5-Dimensional Gravitational Raman Scattering: Scalar Wave Perturbations in Schwarzschild-Tangherlini Spacetime

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 O(G2)O(G^2) by matching effective field theory with ultraviolet solutions.

Two-neutrino ββββ decay to excited states at next-to-leading order

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.

DD-Dimensional Modular Assembly of Higher-Derivative Four-Point Contact Amplitudes Involving Fermions

This paper introduces a robust, DD-dimensional modular framework that systematically constructs higher-derivative four-point contact amplitudes involving fermions by combining gauge-invariant kinematic blocks with permutation-invariant polynomials, thereby ensuring manifest compatibility with the double-copy program and facilitating the generation of operator towers for gauge and gravity theories.
