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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper identifies and proposes a numerical procedure to eliminate nonphysical infrared oscillations in gravitational wave spectra from domain wall simulations, ensuring accurate predictions of the infrared slope critical for observational tests like NANOGrav while demonstrating that naive long-time extensions using the PRS prescription yield incorrect results.
This paper presents a unified holographic QCD framework that resums even-spin gluonic exchanges, anchored by lattice QCD gravitational form factors, to accurately describe exclusive heavy quarkonium photoproduction across the full energy range from near-threshold to high energies while revealing the limitations of fixed-spin approximations for extracting gravitational form factors.
Using hard-dense-loop perturbation theory, this study computes the longitudinal pressure and magnetization of strongly magnetized cold isospin-asymmetric quark matter, revealing that pressure increases monotonically with chemical potentials, the system exhibits paramagnetic behavior, and strong magnetic fields induce pressure anisotropy by suppressing transverse pressure relative to longitudinal pressure.
This paper demonstrates that in an GUT with an adjoint and complex symmetric Higgs sector, two distinct parameter choices can yield identical effective potentials for symmetry-preserving vacuum configurations yet exhibit fundamentally different transverse stability, with one forming a local minimum and the other a saddle point with six negative modes.
This paper proposes a three-flavor chiral quark-diquark model where the parity doublet structure and chiral-invariant mass of baryons originate from scalar and pseudoscalar diquarks bound via gluon dynamics, successfully reproducing the baryon spectrum and predicting a distinctive inverted mass hierarchy for nucleons and hyperons as a signature of chiral symmetry restoration.
This paper presents state-of-the-art predictions for heavy jet mass distributions in hadronic Higgs decays by computing next-to-next-to-next-to-leading logarithmic resummation in the dijet limit and next-to-next-to-leading logarithmic resummation including Sudakov shoulder effects in the trijet limit, matched to next-to-next-to-leading order within Soft-Collinear Effective Theory.
This paper proposes a quantum electrodynamics model for massive dyons based on a gauge group that abandons the Dirac quantization condition, and rigorously demonstrates its quantum consistency by proving it is free of anomalies and multiplicatively renormalizable at all orders using BRS algebraic renormalization and the BPHZL procedure.
This paper presents a novel framework that combines Gaussian Process priors with invertible neural networks to reconstruct parton distribution functions (PDFs) from synthetic matrix-element data, effectively preserving physical constraints and extrapolation properties while learning a posterior distribution consistent with limited Ioffe-time data.
This paper employs a semi-relativistic hybrid quark potential model to systematically investigate the spectra and fall-apart decays of singly-heavy tetraquarks, concluding that while most predicted states are compact and lie above meson-meson thresholds, specific experimental resonances like and cannot be explained as compact tetraquarks, whereas others such as and are consistent with the tetraquark interpretation.
This paper investigates the thermodynamics of a photon gas within the Magueijo-Smolin formulation of doubly special relativity, deriving and numerically evaluating key thermodynamic quantities that smoothly recover standard special relativistic results at low energies while exhibiting systematic suppression near the Planck scale due to the invariant energy cutoff.
