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 investigates the internal structure of the and hadronic states by modeling various molecular and bare-state scenarios to predict and correlation functions, demonstrating that these observables are highly sensitive to coupled-channel effects, short-range dynamics, and the degree of compositeness.
This paper investigates helicity correlations and topological structures in electron-positron pairs created by time-dependent electric fields using Dirac equation solutions, demonstrating how pulse parameters influence momentum distributions and enable the generation of maximally entangled helicity states.
This paper demonstrates that the Cosmic Neutrino Background significantly alters dark matter self-interactions mediated by neutrino forces through a screening effect arising from the interplay of vacuum and background potentials, thereby reshaping viable coupling ranges and suppressing Sommerfeld enhancement for dark matter annihilation.
This paper investigates the phenomenological implications of non-standard momentum dependencies in a -symmetric Higgs portal, particularly within Composite Scalar Dark Matter models, demonstrating how future lepton colliders like FCC-ee can probe these hidden sector interactions through precision measurements of Higgs correlations and radiative corrections.
Motivated by recent BESIII data, this study employs QCD light-cone sum rules to calculate the form factors, branching fractions, and various angular observables for the semileptonic decay , finding results that are in good agreement with experimental measurements from BESIII and CLEO.
This paper investigates how deviations from unitarity in the leptonic mixing matrix, arising from either heavy or light sterile neutrinos, modify coherent elastic neutrino-nucleus scattering and elastic neutrino-electron scattering, presenting sensitivity projections for a future upscaling of the CONUS+ experiment that demonstrate its potential to probe TeV-scale new physics.
This paper strengthens the case for an ultraviolet fixed point in asymptotically safe dilaton quantum gravity using gauge invariant flow equations, demonstrating that the resulting scaling solution can simultaneously describe early-universe inflation and late-time dynamical dark energy.
This paper presents a complete calculation of -meson decay widths up to corrections within and beyond the Standard Model by deriving analytic expressions for all matching coefficients of two-quark operators and previously missing weak-annihilation contributions, thereby finalizing the theoretical framework for non-leptonic -quark decays relevant to -meson lifetimes and addressing tensions in QCD factorization.
This paper introduces a constructive asymptotic regularization method for quantum field theory that isolates and subtracts ultraviolet divergences by decomposing integrand asymptotics, thereby preserving covariance and gauge symmetry while offering a novel derivation of logarithmic terms independent of standard renormalization-group flows.
This paper utilizes NuSTAR solar X-ray observations from the 2020 solar minimum to derive significantly improved 95% confidence level limits on axion-nucleon and axion-electron couplings for axion masses below eV, establishing solar X-ray monitoring as a powerful method for axion searches.
