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 proposes that spinning black holes in the Milky Way can act as persistent "scalar sirens" by ejecting light scalar particles via superradiant instability, thereby generating a detectable, high-velocity scalar background that offers a novel, independent probe of isolated black hole populations and scalar field properties.
This paper demonstrates that the RES-NOVA experiment, utilizing archaeological lead crystals, can probe neutrino non-standard interactions (NSI) at levels comparable to current global fits in its nominal configuration and potentially surpass them with improved energy thresholds or increased exposure, particularly in the electron and tau sectors.
This paper presents a comprehensive study of heavy flavor baryon spectroscopy using a quark-diquark effective mass formalism under two interaction scenarios, successfully predicting the masses of various states that align well with experimental and lattice QCD data by incorporating constituent masses, hyperfine interactions, and a mass-dependent binding energy term.
This paper demonstrates that for shift-symmetric scalars in de Sitter space, a quantum anomaly in renormalization forces the late-time wavefunction to acquire an imaginary part that is entirely determined by its renormalization scale dependence to all loop orders, thereby establishing an infinite set of relations among correlators of massless fields and their conjugate momenta.
This paper compares explicit symmetry encoding (L-GATr) and implicit structure learning (OmniLearn) in particle physics, finding that both approaches achieve comparable performance across challenging tasks like unfolding and anomaly detection, suggesting that efficiency gains from encoding known physics structures are largely method-independent.
This paper develops a general formalism for computing physical observables in the background field approach by representing propagators as path-ordered exponents, applying it to DIS dijet production to derive a cross section valid in arbitrary kinematics and demonstrating its consistency with known results in both back-to-back and small- limits while providing a quantitative matching between these regimes.
This paper investigates axion-neutrino interactions within Type-I and inverse seesaw models, finding that while the effective coupling is constrained by astrophysical limits on axion-electron couplings, the resulting optical depths for axion-mediated neutrino scattering are too small to produce observable signatures with current sensitivities.
Using 3D neutrino-magnetohydrodynamic simulations of a magnetorotational collapse, this study reveals that neutrino flavor conversion is driven by both matter effects and magnetic interactions, leading to significant orientation-dependent event rates at neutrino telescopes that are crucial for interpreting joint neutrino and gravitational wave detections.
This paper presents a streamlined method for constructing exact black hole solutions in non-commutative gauge theory using the Seiberg-Witten map, revealing that non-commutativity resolves temperature divergences during evaporation, induces phase transitions, and suppresses particle emission correlations.
This paper systematically investigates the scalar sector contributions to the electroweak oblique parameters , , and within the 3-3-1 model with right-handed neutrinos, demonstrating that the parameter imposes stringent constraints on the model's scalar masses and energy scales.
