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 calculates the magnetic moments of decuplet baryons in asymmetric magnetized nuclear matter by combining the chiral SU(3) quark mean field model for effective masses with an extended chiral constituent quark model that incorporates Landau quantization and decomposes contributions from valence, sea, and orbital angular momenta.
This paper presents a Mathematica code named StableWein and a machine-learning tool to assess the boundedness from below of the -symmetric three-Higgs-doublet model by iteratively applying necessary conditions and achieving over 99% classification accuracy.
Using heavy-nucleus effective field theory, this paper derives a universal "double-weak Sirlin function" for two-neutrino double-beta decay that significantly distorts electron energy and angular spectra, necessitating the inclusion of these radiative corrections in high-precision Standard Model tests and nuclear structure extractions.
This paper investigates unexpected anomalies in CMS experiment data identified by the OmniLearned foundation model, finding that while background estimates perform well in validation regions, they fail to accurately model the signal region, prompting a call for further scrutiny.
This paper introduces a velocity-dependent two-scale model to demonstrate that cosmic string networks with small-scale structure generally attain a linear scaling regime through gravitational backreaction, albeit with significantly reduced energy density and root-mean-squared velocity compared to smooth strings.
This paper establishes a general, relativistically covariant theoretical framework for the semi-inclusive deep-inelastic scattering cross section and spin observables on a polarized spin-1 target, expressed in terms of invariant structure functions and valid across all deep-inelastic final-state regions.
This paper develops a light-front theoretical framework for semi-inclusive deep-inelastic scattering on a polarized deuteron with spectator nucleon tagging, deriving tagged structure functions and spin asymmetries that highlight the role of the deuteron's D-wave component and provide essential tools for future experiments at Jefferson Lab and the Electron-Ion Collider.
This paper demonstrates that in holographic light-front QCD, a tower of hard exclusive amplitudes with a Poisson-distributed Fock expansion generates a spectral function that encodes the full Regge spectrum and provides an analytic representation of physical form factors invariant under continuous deformations of the average parton multiplicity.
This paper demonstrates the feasibility of simulating the thermalization dynamics of minimally truncated SU(2) lattice gauge theory on current noisy quantum hardware by successfully matching error-mitigated results from IBM quantum computers with classical simulations for chains of up to 101 plaquettes.
This paper presents a fully analytical framework for calculating spin density matrices in cascade decays of baryon-antibaryon pairs produced in electron-positron annihilation, revealing that maximal parity violation yields fully polarized but non-entangled final states, while $CP$-conserving charge-conjugate decays of polarized pairs generically exhibit quantum entanglement amplification.
