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 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.
This paper develops a consistent field-based perturbation framework to analyze the impact of oscillating generalised axion-like quintessence fields on cosmic structure growth, demonstrating that the standard effective fluid description fails during this dynamical phase.
This paper presents a theoretical analysis of the decay using the chiral unitary approach, demonstrating that the inclusion of a dynamically generated resonance alongside other intermediate states successfully reproduces recent Belle experimental data and supports the interpretation of as a meson-baryon coupled-channel state.
This paper benchmarks three exclusive nuclear ground-state shell models implemented in the NEUT neutrino event generator against recent JSNS measurements of missing energy from a monoenergetic neutrino beam, finding that spectral function models outperform relativistic mean field models and that accounting for missing energy thresholds allows all tested nuclear models to be statistically accepted.
This paper demonstrates that operating the Short-Baseline Near Detector (SBND) at Fermilab in off-target or beam-dump configurations significantly suppresses neutrino-induced backgrounds, thereby substantially extending its sensitivity to probe various new physics scenarios such as light dark matter, axion-like particles, heavy neutral leptons, and meson-portal models.
