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 computes next-to-leading order radiative corrections to the process by incorporating the non-perturbative pion structure via the generalized vector meson dominance model, comparing these results with the naive scalar QED approach to quantify model uncertainties for radiative return experiments at flavor factories.
This paper utilizes the Hidden Gauge Formalism to predict six bottom-strange molecular states, identifying specific mass values for and partners of known charmed mesons and interpreting recent LHCb observations around 6100–6160 MeV as and molecular states.
This paper derives master formulae for tree-level and one-loop scattering amplitudes of arbitrary photon numbers in scalar and spinor QED within non-null background electromagnetic fields using the worldline formalism, thereby extending previous constant-field results to account for realistic laser-plasma dispersive properties through a systematic expansion in the non-null parameter.
This paper demonstrates that a universal Hagedorn temperature derived from string dynamics successfully describes the hadron spectra and thermodynamics of all quark flavors, including heavy charmed hadrons, without requiring additional parameters beyond current quark masses.
This paper investigates the detection prospects of gravitational-wave displacement memory signals using future space-based interferometers, demonstrating that such soft signals from compact binary mergers and scattering events can be independently measured by a single LISA-like detector and precisely constrained by a LISA-Taiji network.
This study utilizes the string-melting AMPT model to demonstrate that in symmetric nuclear collisions at 200 GeV, charge-dependent directed flow splitting exhibits a distinct baryon-meson dichotomy driven by transported quarks during the partonic phase, with significant system-size dependence at high transverse momentum that establishes a baseline for interpreting electromagnetic field effects.
This paper proposes a non-perturbative analytical framework for QCD based on a mass gap derived from tadpole/seagull terms, which yields a singular gluon propagator that explains color confinement, linear quark potentials, and scale violations by revealing a more complex dynamical and gauge structure in the QCD ground state than suggested by standard Lagrangian symmetries.
This paper proposes that the cusp-core problem in dark matter halos can be resolved within the standard cold dark matter paradigm by suggesting that fermionic dark matter forms degenerate cores in subhalos, which collectively deplete the surrounding density to create observed core profiles without requiring strong baryonic feedback.
This paper proposes a unified, ultraviolet-finite framework based on Holomorphic Unified Field Theory and nonlocal regulators that derives the complete Standard Model mass spectrum, mixing parameters, and gauge coupling unification from a single holomorphic action with minimal free parameters.
This paper proposes a method to assess theoretical uncertainties in Effective Field Theories by leveraging the invariance of physical observables under field redefinitions to validate power-counting schemes and generalize uncertainty estimation from the Standard Model to non-renormalisable interactions, demonstrated through a case study in Higgs Effective Field Theory.
